Thank you for igniting my own passion in science. 2.1K History of the Universe Reply 149 replies icepool02 icepool02 1 month ago in the last several years of watching physics and cosmology lectures on youtube, this is the first one that explained the logical leaps that lead to our current theories of the universe. the impression i've gotten before is that einstein and all the others were some sort of crazy geniuses that came up with fantastical assumptions that happened to be correct. it was very refreshing and grounding to actually be able to follow the how and why these ideas came about 91 Reply 5 replies Paul Caple Paul Caple 2 months ago These videos, along with the History of the Earth ones, are probably the best produced and highest quality on YouTube. Not only beautifully presented and narrated, it has this almost poetic quality. Then there is the shocking mind-expanding content, like undergoing a form of deep meditation. Bravo! 154 Reply 7 replies Johannah Underwood Johannah Underwood 2 months ago I came to this by chance (or was it predetermined?) when it began to play after something completely unrelated ended. I looked at my tablet and saw its subject matter, and being interested in science fact and fiction I let it play. This is one that I know I will come back to again and again. It's genuinely fascinating, well explained, and the narration and music are relaxing to take in. I'm going to subscribe now and listen to your other videos. 51 Reply 3 replies Chris Chris 1 month ago The immediate existential dread upon hearing the last line... Masterclass writing!

And of all this channel's videos I liked this one the most. With its stellar amount of content, perfectly executed presentation and calm narration it is a joy to watch. Even though I already knew about many of the things it touches, there was not a moment I was not on the edge of my seat. Everything is so nicely embedded into the history of discoveries. I wish there were videos like these 30 years ago. Had I watched them back then when I was young I very well might have chosen a different career path...

Bravo. 16 Reply 2 replies Bobby Winston Bobby Winston 2 months ago (edited) I can grasp many of the theories and functions of the universe/reality when explained well, like this, and even a little deeper/more complex and described in a less rudimentary, "user freindly" fashion. But i cant understand the math or working out any equations at all. I took 1 physics class in high school, then 1 semester in college (despite how i barely scraped by in HS) because i find it interesting and wish i was smart enough to pursue this field, but i withdrew from the class at the deadline, i had 0 chance and was so lost and overwhwlmed. I really cant do mathematics of any sort sadly. My professor would still answer my questions very nicely despite it revealing to him that i wasnt gonna make it in that class. He politely told me twice to withdraw while assuring me that it waa ok & i wasnt dumb. He waa really cool. He also said i was smart and could understand theories and the universes functionality, reality, & the sheer scaling or size of the numbers and infinity, but my brain wasnt mathmaticaaly gifted. He told me to pursue philosophy and 6 years later i am a philosophy teacher in HS, which is hard to find. He was My favorite professor, and i only had his class for like. 7 or 8 weeks 9 Reply 1 reply Federico AE Federico AE 5 months ago Once this series is finished, you should start a Kickstarter or something like that and release it on a Bluray box set.

Forged right in the supernovae of the production of this series. Can't wait to see next episode as usual. Thank You !!! 95 Reply 5 replies Eva Lopez Eva Lopez 8 days ago Loved how some specific subjects can destroy your brain, like: time, gravity (and what is a "force"), visualizing an object in "higher" dimensions, conceiving infinity, the end of your own perception. Compare to those, understanding how our own brain works seems like a peace of cake, yet we still don't know that one either. Reply Richard Paxford Richard Paxford 2 weeks ago "What happens at the boundary between expanding, and non-expanding space?" Holy crap, I hadn't even thought about that! I just accepted that the universe expands but some bits stick together, now I'm baffled 😅 Reply Goran Mancevski Goran Mancevski 2 months ago Any thought, word and animation in this video is on its place. True, beautiful creation. I was feeling something was missing in all videos across tube I have seen so far. You filled that gap with honnest questions. It seems smooth when you speak, but I recognize the effort and deepth assembling this. 1 Reply Isidari Isidari 1 month ago This sounds a lot like the way the book The Fabric of the Cosmos explains things- but this is still pretty well done and of course, the information is true anyway, so it's great that you basically turned it into a video :) 3 Reply 2 replies Talymo Talymo 2 months ago No one explains the complexities of our universe quite like this channel.

Good job! 35 Reply John Kim John Kim 2 months ago This is what truly matters. I’m sure the answers to most ,if not all, the questions we have about anything can be found by looking out to the stars. Imagine the wonders humanity could achieve if we could just come together and reach out. 2 Reply We Love Weekends We Love Weekends 1 month ago (edited) WoW Firstly, thank you for taking the TIME to put this very easy to follow and understand esamble of brilliance together. It is so greatly broken down into simple forms of each dynamic and put together with very well chosen graphics making the overall story easier to take in. This is coming from a person who once avoided things like quantum dynamics/mechanics& physics because it hurt the hed to understand but now find myself in a place where i am writing my own theories based on nothing more than desire and slowed down by my own "education" i never felt qualified to even speak loudly about my discoveries, never mind write them down. This video is a trully brilliand gathering of every field i am interested in and manages one to continue to think about all things RELATIVE without having to be an expert in all of the fields required. It must have taken alot of thought and alot editing/re-editing and difficult to prodoce. Kudos and again... Thank you! Reply 1 reply chris kelly chris kelly 2 months ago Your scripting is fabulous. I want to imagine you labour for long hours musing over the right phrase, the right word. I often think everyone does thing the same way as I do. Skirting philosophy and history and the ideas and processes that bind them into one story. Like James Berk, you sir are a steely eyed missile man. Letting us all know about that day the universe changed. thank you. 5 Reply open left open left 2 months ago (edited) These videos are like crack to my mind.

If I remember correctly, time slows the closer you get to a BH, but that means, it slows for you. From your point of reference, everything "outside" the influence of this effect would seem to accelerate in time. So from your perspective, the end would come even faster now. Getting near to a BH is like pushing the fast forward button on the universe, from your point of view. It makes no sense, if extending your time was your goal. 1 Reply 1 reply Stephen Walton Stephen Walton 2 months ago (edited) When these questions overwhelm me late at night and keep me from sleep, I just remember the words of the doctor, it explains one thing anyway: “People assume that time is a strict progression from cause to effect, but actually from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly, timey-wimey stuff.” 2 Reply Samrat Chattopadhyay Samrat Chattopadhyay 5 months ago I am happy to have discovered this astounding channel...one of the best on YouTube in the astronomy category. 👍🏻👍🏻 48 Reply Anvy Anvy 1 month ago The weaving together of scientific exploration and the destiny of consciousness is awe-inspiring! Reply Aidan Brumsickle Aidan Brumsickle 13 days ago The thing about the big bang introducing low entropy and that creating an arrow of time made me think of our conception of our universe as a stripe or enclosed area of spacetime almost topologically closed from other areas Reply Norman Gensler Norman Gensler 1 month ago Well done. I would be interested in a video that adds, to these thoughts, the concept of purpose. Almost endless complication, I'm sure, but what would be the why of the universe? Is it possible that there is no purpose to everything around us, or does its existence provide the framework upon which to understand purpose? 1 Reply 1 reply John Divver John Divver 2 months ago Astonishingly good - I wish I’d discovered these earlier! 1 Reply Carl Bernroth Carl Bernroth 2 months ago "For a brief moment you exist as a knot in the fabric of eternity", I don't find that disconcerting, I find that incredibly humbling and inspiring.

Reply GIANT INTERNET NAME GIANT INTERNET NAME 1 month ago Since black holes only have the properties of particles (speed and direction), scientists are now beginning to equate wormholes to entanglement.

A "tiny" affect is the reason we have mostly matter vs antimatter and also why we exist and have clusters of stars, life, etc Tiny on the scale of time or size cannot be overlooked as that means reversing time does mean something major Reply MAG320 MAG320 7 days ago Not even Oxford University can sum things up like this within a hour.

But mechanical systems aren't all reversible because when running forward, energy is lost over time in various ways. Therefore, the simulated behavior won't return a system to its previous state. The energy being reinserted into the system is not simulated, and as a thought experiment, it would be returned if time actually ran backward.

Thank you Reply Chipmasters Online Chipmasters Online 5 months ago (edited) I usually never comment on any video with YouTube. And personally I like watching this channel as my top channel. Helps me learn alot too! But of all the videos this channel ever produced. This by far is probably the best episode of any program I have ever seen in my 45 years of interest in this topic. In fact it is so good, and if you are a science person, it will make you shed a tear at the very end until the credits roll. I have never experienced that ever in a science program. Maybe close with Carl Sagan. And you truly can be compared to Carl Sagan today, over any other person who tries to express or explain Einstein's Theory of Relativity. Or Space and Time. It is one thing that makes you sit back and wonder about the God of the Gaps. Is it truly possible, there is a God in how we have been created from nothing? Only with this episode, I had that thought pass in my mind. Weird. I never expected it. And I'm not some religious guy either I can tell you that for sure. But as Proximo said in the movie Gladiator. "We are shadows and dust"! How true this will be in our future. And to understand that even the hint of space and time may not even exist, but only from our perspective. Is intriguing. Hmm? And even better yet. Your explanation of Relativity, and Space and Time, is now meaningful to me. I always had a tough time grasping the full concept and piecing it together. But you opened my mind of thinking again. And you were able to explain it, in a way, that it became simplistic to truly understand in the end. I truly hope a part 2 is being made. And that it rides off the back of this episode. Not to mention, I quadrupole(and more) watch all your videos. Can't get enough! Good job Mate! This channel is definitely on a good path in our time. 28 Reply 14 replies Angel Rodríguez Angel Rodríguez 2 months ago (edited) The end of the universe is like human death 😖 we would try to lengthen the last moments, but in the end it will only be darkness.

The speed of light is based on a time unit which varies depending on how fast (and in what direction) you are traveling. The best model is what I see as our whole universe is traveling in one direction towards what we call "the future" There are off ramps (wormholes) that can get you somewhere else like a freeway offramp. Some of these just take you off and put you back on the same timeline. Others can take you into the past. We share the sense of time mutually with all creatures great and small in this reality.

However, what I saw presented here is not Leibniz' definition of space and time. He defines space as the relative organization of all contingent monads at any given moment(which assumes there is a true present). And he defines time as the relative organization of moments. He's a B-theorist, holding that all moments exist simultaneously contingently and harmoniously in accordance with God's perfect and infinite will. Unquestionably for Leibniz, God knows the relative positions of everything and everyone, though he would also say there is no such thing as absolute space, no absolute directions in contingent reality or any absolute location of it.

How many previous forms have your particles been assembled into? Have your particles been in dinosaurs, volcanoes, the primordial soup? Maybe your particles were in several places at the same time, perhaps some were animals, plants, rocks, lakes, ocean, at the same time? Incredible that DNA can assemble those particles into every life form that has ever existed. And that all DNA are related. And that DNA itself is also particles. So what created DNA?

I've been told that "time is the medium of change". (Fair enough, too. It is.) My own thought is that time and space are both absolutely rigid and that there can be NO change. My belief is that your consciousness (your perceptions?) travels through a multi-dimensional 'world' which consciousness itself samples "in sequence". So we have no Free Will (and neither would any divinity/ies). My nearest analogy (thank heavens I was a projectionist once) is a movie, static images projected (sampled) in sequence; nothing changes (nothing can change, can it?) but the illusion of movement is perfect. To upset you a bit to help get my point across, out there in the future you (yes, you) are already dead; your very own personal death is out there right now waiting for you to reach it. And, in a thousand years ahead from now how different will you be from a thousand years back? There's just one guaranteed 'variable' out there, and that one is death. You are alive right now, so your birth was inevitable and has been since the dawn of time—nothing could have prevented your birth, nothing. And sadly, likewise, at the other end ...

Time becomes space in the presence of matter. The more matter there is, the less time there is and the more space there is. If there is less time, then there is less time to travel through, so it will take shorter (we say that time has sped up). Whereas if there is more matter in one direction, then there is also more space (maybe space IS matter; there is no truly empty space). If there is more space in one direction, then you are more likely to go in that direction because there is more to go to (so space seems curved and matter is drawn to other matter). Just an idea of how to think about it. 1 Reply DanjaTube DanjaTube 1 month ago if matter is ultimately composed of probability, then one can say that space is composed of possibilities.

Reply Thomas Hopkins Thomas Hopkins 2 months ago All of space time exists simultaneously but is effected by what is in it and the attributes of the objects in space time determine the effects of space time on the objects. For example: picture a leaf, a small boat and a large boat on an ocean. The ocean represents space time and the objects mentioned represent anything that exists in it. Like the water in the ocean space time is indistinguishable from any point within it and if it was somehow transferred from one location to another it would continue to be indistinguishable from it's surrounding space time. Like the ocean space time is effected by internal and external influences that effect the property of space time such as density and current flow. Space time effected by extra dimensional properties and internal landscape structures that exists within it. The air above the ocean is another form of the water in the ocean but not as dense as the water in the ocean and also exists simultaneously but has it's own properties effected by external influences as well. Glaciers exist in the ocean and can melt into the ocean or the ocean can freeze into glaciers depending on the external influences that effect it. I couldn't possibly begin to try to explain it all mathematically but I don't really need to. It is what it is! Reply Mr Mr 1 month ago Yin begets Yang and vice versa, yet they annihilate each other.

If time had always existed, it would be infinite, which means that no matter how many years went by, we would never have reached today. If an observer had counted every day that ever went by, then it seems logical that we would have an actual number, and as every number is finite, it would NOT be infinity... So it seem like time has to have had a beginning, but what kinda ultra exotic "mechanism" could start the flow of time? And even more curious is how this could have happened if time does not exist in the first place. AFAIK; nothing can happen without the passing of time... Some people may be tempted to say that time is just a human construct, and in reality there is only the "now" - but there is always a "before" and "after" an event takes place. One thing leads to another, and today would not have been as it is if it was not for all the things happening in the past. So time seems very real to me... In case someone believe that God created the universe and time and all that, then when did time start in Gods dimension? Some people say that God exist outside of time, but i would still be tempted to say that there would be a before and after God does something, which means that time had to exist on some level of reality even for God to do something...

Tbh I think it's much simpler than that (thought experiment wise, not mathematically): I think on a quantum level there was one thing in the beginning and when space began expending, "it" stayed connected/entangled.

The black hole around which they have built their civilization does not give them time, it robs then of it. The closer you get to the black hole, the faster the outside Universe appears to tick, compared to your own time. (If you were falling into the hole, yes, the external Universe would perceive you as surviving to the bitter end of time before disappearing into the hole, which sounds pretty good from the perspective of wanting to survive as long as possible in absolute exterior terms -- but from your perspective, and that of these Ancient Aliens huddling close to the central hole, you/they would see the entire remaining history of the Universe elapse before your eyes, above your head, in what you experienced as just a few moments. You have squandered the entire remaining history of the universe by spending it too close to the black hole. This is exactly the opposite of what you wish to do when the Universe is nearing its end. You want to get as far away from the black hole as possible, so that you experience the remaining lifetime of the universe as taking as long as possible. Gee, if only there was such a thing as Antigravity, and a white hole that bent space the other way , stretched or compressed time in the opposite sense, so that even a moment of exterior time lasted centuries, Millennia, or forever, from your perspective, huddling close to the white hole. That's what the ancient people should have been looking for or trying to produce! By being close to a black hole instead, the Universe's remaining years or millennia pass in a moment and you/they have wasted/lost them.

Reply Pfhorrest Pfhorrest 5 months ago (edited) The most fundamental concept is that of possibility: all the states the universe could possibly be in form a set, a set that is partially ordered by the entropy of those states. Time is just the "direction" of that entropic ordering: two minimally-different possible states of the universe are before or after one another when one is more or less entropic than the other. (This does imply that there are multiple pasts and futures of any given state, but due to the nature of entropy there will necessarily be fewer pasts than futures, so "over time", following along that entropic ordering, pasts converge while futures diverge, which accounts for why the past seems fixed and the future seems wide open. This also implies that there is a "perpendicular direction" to the direction of time, consisting of all those states that are co-present with a given state, neither pasts nor futures of each other. Those are the superposed classical states within the universal wavefunction.) Space, then, being the most derivative of these concepts, is just the time it takes for a change to one part of the universe to propagate to another part of the universe. 11 Reply 3 replies First Last First Last 2 months ago Simulation.

We understand that there is matter, but what is so difficult to accept that there is the possibility of a space with the absence of matter? An absence of everything except the knowledge that such a condition exists (because we technically wouldnt be able to experience it). Perhaps the universe is simply just the collection of matter, in which case the outside of the "Universe" is simply a vast gap until we approach another universe (a collection of matter with mechanics similar or different from the universe we reside in) that is to say if such a concept exists. Otherwise, there is no outside of the universe, and instead the term universe is all encompassing of everything that exists, regardless of whether any given instance of matter is collective or individual. Similar to how the surface of our planet works, we walk around and around until we reach the same spot from which we started our journey. In this case, the only way to travel outside the "Universe" would be to enter a sort of doorway that leads to a reality seperate from our own. The experience would be similar to entering a virtual world. We don't physically exist in such a reality, but rather our conciousness explores that reality because as an individual being we percieve that reality as one that may have varying similarities and/or differences compared to our own. It may be entirely possible that what we are looking for with math measurements and readings from instruments is something that we simply cant quantify, like the concept of infinity: infinity will always be infinity because it entails a magnitude outside our comprehensible range of description. I just don't think its appropriate to reject the theory that space can exist without matter. It's like saying a piece of paper doesnt exist just because we havent put anything on it. The paper is there, it was made to contain concepts and messages. It's just a blank paper (conceptually, not physically. That would entail that we could bend fold and rip the paper, which isnt the point of this analogy). Acknowledging the presented concept of time, I agree that time as well as speed is relative. The simple fact that things happen and the entirety of existance isnt just one pose is evidence enough that time exists to an extent. However, the electron video example I think is a little biased because the video is mirrored both forwards and backwards, so upon any given perspective it would seem like the same image but that doesnt mean it is. Something is different about it whether we can see it or not. Its just an illusion. Lastly I just want to say that time travel has an absolute ton of things that have not been considered. Like the fact that the processes of our bodily functions rely on time, and just stating that a human can travel through different points of time completely glosses over that issue.

Reply Harry Hockman Harry Hockman 1 month ago (edited) The old Universe (all the mass in a small, maybe earth sized) became, for a short time, a Galaxy Creating Machine! The first thing that this machine did was create one huge spiral galaxy with black hole in the center, between both Sides (of the old Universe, it was an inside job; soon to be new universe) pushing full blast against each other (We should all know because We all had to choose sides back then and probably push with all our mental might! We all (all the Beings in this/old Universe) knew what was happening; We were all there. We are all eternal; where else would We all have been at this moment, with our Awareness & Consciousness, We had no form and We know all the beings that manifest anywhere intimately.) creating that first large spiral galaxy with one very large black hole in the center)! The tremendous stress blew both Sides into countless Pieces, each Piece pushing on those near it creating many, many more spiral galaxies and much dark matter thrown out through the plane of the spiral galaxies. The Progenitors (the old Universe in pieces) that created all this are Quasars now. Most Quasars pushed each other to the perimeter of our new Universe. From there they they form a basket like pattern* all around the new Universe. They are responsible for our gravity and moving electromagnetic vibrations and much more. Some Quasars stalled and remained in the physical Universe. The JWST will allow Us to understand what happened back then. We all can see, as well, that We were always a part of whatever this Universe was/is involved in… “out of the One many, out of the many One” 1 Reply 1 reply Kenny Pridemore Kenny Pridemore 2 months ago Unconsciousness is timeless , therefore time cannot effect it, time can only effect consciousness ..... while unconscious, time and space ceases to effect anything . 1 Reply landoc05 landoc05 5 months ago Mathematically a problem with Many Worlds is "where does the energy to produce the branching universes come from?" What many fail to explain is that a consequence of the equations properly applied is that there is no branching out, that's pop science: ALL possible timelines have always existed! That's much easier to understand if there is no time at all. The "Big Bang," the present, and the future death of the universe all happen simultaneously. Since we're trapped inside this universe and subjected to its gravity, we perceive spacetime. For an external observer, outside this universe, however, the entire thing is tiny and exists for a tiny instant. That would also explain dark energy: particles that seem to emerge from nothingness for a tiny fraction of a femtosecond. To us, they pop out of nowhere in the deepest recesses of our space. But for creatures trapped inside such tiny, fast events, they are entire universes, huge and lasting for eons. 6 Reply 2 replies AAA BBB AAA BBB 2 months ago (edited) the animation of two dots bouncing off one another, whether played forward or backward would appear the same to the audience, only because there is a lack of information (only two dots), so no one would be the wiser. whereas a more complex scene, when played backward, audience can easily tell it is being played backward, because there are way more information to tell the difference so the author's analogy for electron is not very suitable to explain why quantum particles do not experience time normally 1 Reply Norman Dubowitz Norman Dubowitz 1 month ago Poetry!

Why would the civilization want to move close to a black hole where time dilation would mean that they would experience aging (time) more slowly, but only relative to anywhere in the universe other than near a black hole? From their perspective, as they would experience time, they would not live longer life spans. Also, the universe would be evolving, relative to them, at a much faster pace. So the universe would age, let's say, a thousand years for every month they experience. That would mean that after living only one month, the universe would have evolved 1,000 years closer to thermal death. If anything, they would want to live in a place where the relative time would be the reverse of that. Somewhere where they would live a thousand years, while the universe got only one month older, thus providing life for many more subsequent generations. And it wouldn't cost them any longevity because their experience of time would always feel the same. 5 Reply 2 replies Alan Zimmerman Alan Zimmerman 2 months ago (edited) Certainly you would know when you are moving by observing the water moving in the fishbowl.

It would be better to live where time passes more quickly for you relative to other places, if you are trying to live longer before the end of time.

It is also the final definition of "nothing" and "always". Time is of no relevance in such conditions, unless some "event" occures, afterwhich time can be "counted" referenced to that event which would of course be time zero.. Such an event could for example be the introduction of the very first particle of matter into that endless empty space.

Reply Michael Flack Michael Flack 1 month ago Space being the distance between things. And time being the measurement of movement of those things. It's after this that things get bogged down by supposition and limited theory. Example: when science has yet to observe something that can move faster than light it assumes that this is the case and is undisputed, until of course it does in fact observe such a event. So in the mean time it assumes that time is light measured and absolute and time travel occurs because they assume it is not possible. Opposed to simply stating that moving so fast would impact the movement of of surrounding objects and as such the measurement does not change and time itself is not altered. PS: it's as silly as going to a high place and stating people look small therefore they are now small... moving faster can create this perception but the fact is outside of the zone of impact the movement of other objects is the same and unaffected therefore the overall measurement of time needs no "readjustment" and continues as normal.

Reply Wayne Biro Wayne Biro 1 month ago They are both tools that we invented to give units to relative differences between objects (however they are defined). Nothing mysterious. Nothingness does not need them, nor do infinity or eternity, and all three of those do not exist in the physical world. Infinity is the background nothingness in which everything (hypothetically speaking) exists. As for 'everything', it cannot exist given infinity, so if you've grabbed 'everything', you've actually grabbed 'nothing'. Congratulations. Eternity is the background changeless in which everything changes (if everything could exist). If the universe had a beginning, however, then it is not infinite or eternal, and matter and energy would be finite (and THEN you could grab 'everything' for yourself, but that would be pathologically suicidal). Have a nice life, and get a clue (it is now out there in a new philosophy that YouTube does not like me mentioning because they deem it 'self-promotion') (the idiots). Reply Kosteri x Kosteri x 12 days ago 19:00 you're missing the point here. Any understanding of what entropy really is, needs to start with a room of balls. Out of all the possible states that you can make a list of, there vast majority of those states is NOT all balls together in a corner. Now if any random part of space is taken into consideration, it is far more likely that its matter in it is somewhat diffused than that they all sit together. Likelihood aka probability is always taken over the possible states. There are many ways to roll a 7 with two dice but only one way to roll snake eyes.

It would make much more sense to fit as much lifetime as possible into as short a universe time as possible in order to benefit from a warm universe for as long as possible. So no proximity to very large masses and no movement close to the speed of light.

Reply 1 reply James Elliott James Elliott 1 month ago (edited) Time is another version of wave particle duality. The present is the act of observing or measuring time and our consciouness is the tool with which we use to measure it. The future is a wave of probabilities that will forever remain undefined until we observe it in the present and the past is the collapse of that wave function into a defined state. Free will is conserved because it is not time defining what state it will be in in the past from our standpoint of observation. The choices we make ourselves in the present defines what state our past resembles. We can't remember the future because it hasn't happened yet and the past is remembered because it has happened. The past has been made real to us through the observation of time and experienced through the consequences manifesting in the present. Without consciousness and choices, time simply is a quantum field of nothingness like space would be without dark energy and virtual particles. edit: Simply by existing, we are being time travelers. There is not a forward pointing arrow of time. Space and time are a quantum field in which our conscious thought and physical body are traveling through, from the observed past to the future yet to be defined. We are all time travelers right now.

I am not easy to please. Well done! I'm watching, thinking, and considering what we can do with time. Interestingly, is even the effort to study time, write papers about it, do videos is contributing to entropy? If all our energy is put into this, then we are in a death race to figure out how to bring lower entropy before too much information takes us to a state of such high entropy that it is statistically impossible to win the race. The more we race, the faster we lose. We need to side step this. Run the race from both ends, at the microcosm or macrocosm at the same time. Trap time. It's seemingly elastic (via mass). Mass can be applied to ultimately un-randomize other mass through distortion of time (measured as gravity). Perhaps a relatively low amount of energy can be used to create mass from a common medium, such as light, thus creating protonic mass, and artificially start attraction of non-photonic mass and thus reduce entropies. Since nothing is lost in this universe forever, then in theory entropies should be reducible... before it's too late for us lowly carbon lifeforms to do so. Also, aren't black holes already reducing entropy?

Gravity, it appears, is not a force, in a field, carried by a particle, but is an emergent phenomenon caused by the fact that time advances more slowly near a massive object. In this situation, you must move downwards in order to be in an inertial frame of reference. From the surface of a massive object, this movement is not possible because the object is in the way (pauli exclusion principle). This resistance is the same as constant acceleration and we feel this as weight. Gravity is an effect, not something fundamental in the same way that there is no such thing as a centrifugal force, rather there is a centrifugal effect. Seems to me that space and time (or spacetime) are also emergent (effects) with their underlying causes emerging from information. Maybe something like this: Time: The transformation of a probability into a certaintly (knowledge). Space: The degree of quantum entanglement or propagation of information. Just wild speculation on my part but I can't escape the feeling that the only thing that is fundamental in this Universe is information and everything else is just emergent. 351 Reply Arvin Ash · 148 replies Uday Shastri Uday Shastri 3 months ago Liked this video.

I wonder if you have heard the idea which has been suggested by Sir Roger Penrose that when universe reaches "Heat Death", there is no matter left and all energy is uniformly distributed as photons. These photons travelling at speed of light have no time sensation so effectively time stops and also since there is no activity, universe "forgets" how large it is. In other words, large and small become same. Effectively it resembles the initial conditions of big bang and it starts a new creation.

That sounds good Reply محمود محمود 2 months ago I watched the video and I’m glad that you have opened the door for more theories with regards to the time concept as I was always fascinated by the nature of the time and I have my theory as well which is totally different than yours. I think what makes the time is the universe speed in one direction and the relationship of this speed to the speed of light. Therefore because we are lagging behind the speed of the light we feel our time is running in one direction. If our universe speeds little bit to catch up with the speed of the light then our time will stop; if we add little more speed then we can reverse the time as we can be faster than our actions but when that happens our cells will degenerate to go to its basics. However, there is another explanation for the aging happening to us during the process of the time or what I called the speeding of our universe, the explanation is that our cells need energy to overcome the resistance coming from the opposite side during the universe movement, but if we managed to catch up with the speed of the light then the resistance will be zero and our bodies will no longer produce energy and we will be healthy and young for ever.

Time could be switching directions all the time, and if everything runs backwards, including our thoughts and memories, then we would never know it was running backwards at all. 2: I really like the idea that increasing entropy is what defines time. 'Time', as a human word, really represents our perception of this constantly changing state of the universe. It is only because we have consciousness and memory that we can perceive the change from one state of the universe to another state a moment later, and it is only because of our intelligence that we can reconstruct what past states of the universe have been. 3. I agree with your conclusion that in the end, when all energy in the universe has been equalised (so there is no more stored potential energy anywhere, be that gravitational, electrical, heat vs cold or whatever, then there would be no more energy exchange anywhere in the universe. Then, all future states would be the same as the present state, so time would be irrelevant. So I guess my conclusion on this one is that the universe is constantly moving from one state to another, and overall entropy is increasing. But time itself, is an intelligent being's perception of this change facilitated by consciousness and memory. Time only matters because we are here to witness it. If we weren't here to witness it, what would it matter? 26 Reply 20 replies Alex Xela Alex Xela 7 months ago 'It's perfectly natural to go back in time in quantum physics'. Notice the word physics?

What if time is indeed the 4th dimension but also linked to space such as length, width and depth? We measure time in units of seconds, minutes and hours bc our perception of it it's intricately linked to Earth's movement around the Sun and we feel it and measure it as a "duration" or "how long is smthng gonna take".But that might be the issue. What if we look at it bit differently, time might just be the distance of an object already moving ON a 3D space with respect to and "outside" reference frame. In our case, the sun. The "feeling" of past, present and future might be just the distance of earth orbiting at a relatively "low" velocity not "duration" per se. If a person is completely isolated in a box in space with no way to look out at planets or the sun. Would that person experience time? Would that person be able to tell time apart at all? I'm not so sure... If we look at time as another "distance" we have to travel thru...Then it makes sense that the faster we go the "less" time/distance we experience...In simple words...

I’m trying to learn about these things so I at least know the language of physics. 1 Reply N tak N tak 4 months ago What’s brilliant about this video is it’s simplicity in explaining the very complex scientific principles of time and entropy.You are a great communicator Arvin. 3 Reply Stephen Watson Stephen Watson 3 months ago Could you join this theory with general relativity -- ie why does time slow down near masses? 1 Reply Bob Hagel Bob Hagel 5 months ago If the past is definitely known information as aposed to possibilities and entropy increases with the passage of time, then as we put a gigsaw puzzle together and new information is revealed like which puzzle pieces fit and what the picture is, why is entropy decreasing in that scenario?

Reply blueckaym blueckaym 2 months ago While statistical approach (used for example to explain Entropy) can be very useful, it has a big weakness (especially when trying to find philosophical understanding) - it ignores the processes between states, and just draws conclusions what is more and less probably to happen depending on its rarity. This way it seems that randomness would allow for spontaneous lowering of Entropy (and trying to explain it with its extremely low probability), but in reality (yes it's theoretically possible, because we don't know for sure either way) we don't know what will be the PROCESS that naturally creates lower Entropy. This logical fallacy is like the way Many Worlds hypothesis says, there are infinitely many worlds so there's space for a world for each possible combination of things. But the problem is there could be processes that push thing in certain direction, and don't allow for pure randomness to create all (infinite!) possible combinations of things. For example imagine life of Earth (or our life on Earth if you prefer) - there's a ton of things that happen in the universe on daily occasion that can easily exterminate all life on Earth (or at least all life that reached level of civilization). What shields us from such events is that we're relatively distant from most such events. For example planets nearer to the center of our galaxy would be bombarded by much higher radiation and space objects to allow for life like the one we know to exist (if any life at all). But the randomness logic says - "Sure, there's a place for Earth like planet where everything is exactly like it's currently on Earth, with the exception of this small detail ... and another Earth, with this small difference ...etc..." If this actually turns out to be true (which we won't be able to find out ever) is means there IS A PROCESS that turns infinitely many planets to current Earth with only minor differences in each. ... Think of a classical dice - it has 6 sides, and if randomness was the only force ruling it, then with high enough number of throws we would get about 1/6th of each side of the dice. However it's not Randomness that determines how it would fall, but the forces that affects it. What force gave it what energy in what direction, what surfaces it hit with its angles until it lost its energy to finally settle on a given side on the table for example ... It's well established that if you create very precise machine and shield the test environment from outside forces you can throw a dice with the exact result desired. Sure you won't be able to throw it in all possible positions, just because they're infinitely many, and we have very finite time and resources to do it, but the point is there IS a DETERMINATE way to do so! It's NOT RANDOM! What makes it appear random is our lack of knowledge or control over the situation. To summarize, statistics can be very powerful tool to reach practical goals, and/or to find a pattern in something still unknown (if enough data is available), but it can't explain the processes leading the things from one state to another. That's why it's very easy to establish CORRELATION using statistics, but only by statistics you can't establish CAUSATION!

Regarding the reversibility of time in quantum mechanics , I think there is a possibility for the time to be a one way ticket and the diagrams to me don’t prove the symmetry. When a particule decays in two particles, we will never prove that it’s the same two particules which can transform in one same particle. They are identical but not the same!

I have a mystery that I just cant get my head around. I have no idea what study to access to clarify this to me. This is a time and distance traveled question. Picture yourself standing next to the North Poll and another person is standing on our Equator. Both people will travel in a full circle getting back to the starting point in the same time period, as the World turns, but they travel a much different distance to each other. Can this be explained? One must be traveling at different speeds to accomplish this. But if I understand it correctly speed is time over distance. This is a conundrum for me. Any answers anyone? in the above example the answer may be obvious to some but this can also be asked for a time clock dial. As the dial is going around mark the outer most section of the dial A and the inner most with the letter B. As you trace the path of each letter you can clearly see the different distance traveled. Is B traveling faster than A. Yes it is but A and B are attached by way of the dial much like Earth is attached to the the men. I just don't get it. I thank you all for your insights. Could this be the opposite or the reverse of time dealation? 1 Reply Arvin Ash · 2 replies FanBoyShyPad FanBoyShyPad 7 months ago I think time is a measurement we use to scale our readings / awareness of entropy without entropy time would be obsolete because all ordered states would remain in order essentially making everything infinite if everything stays the same time cannot exist Reply Daniela Haidacher Daniela Haidacher 6 months ago what if theres a parallel universe in which time goes backwards.

Very to the point, have a good one :) Reply 1 reply Chris Kennedy Chris Kennedy 1 year ago (edited) Great video - Arvin provides one of the best breakdowns of all of the possibilities that time could be. I heavily lean toward time just being emergent from the playing out of physical laws (entropy, etc...). I think it is as simple as that. Therefore it doesn't make sense to me to think time will run backwards. That would mean that physical laws would alter themselves in a non-sensical way for the sake of time running in the opposite direction. But that is highly unlikely since forward time really plays no role in the real physical laws that we see - forward time is just the playing out of those events while the laws themselves remain consistent and are the driving force every step of the way. One of the keys to expanding our understanding is a deep analysis of time dilation. Because only through understanding why clocks can run faster or slower will we be able to understand what makes them run to begin with. Having said that - all of the time dilation evidence we have so far (muon half-lives, GPS clocks, etc...) seems to point at the fact that each atom is its own personal clock which can be sped up or slowed down based on a change in its local environment. That is consistent with time being emergent from the playing out of repeating fundamental behaviors on the atomic/sub atomic level. 5 Reply 1 reply Thiago David Thiago David 8 months ago (edited) I think that there are two types of time.

I believe TIME, the act of something always having to move forward is something we've developed to keep thing's in order. An order we can control to some level. But if you think about time is constant and is really only THE MOMENT. The moment is not moving forward or backwards it's just The Moment. Time if you refer it to, Back When or I have aged, or any of the similar notions that time has passed and only in the forward motion to me is something I could never put together as a concept. But I can at Moments. It's said that time is invite so if that is the case the every moment is infinite. If something is limitless then it's only natural that even a single moment is infinite. Meaning you cannot compare a million years to one second because they are both infinite. Anyway those are my thoughts. I hope I didn't bore anyone too much.

Reply 3-D Walthrough 3-D Walthrough 1 year ago Hi Arvin, your efforts here are appreciated, as you present different opinions regarding time. The most solid point after watching, was the first one..Nobody knows what time really is.. the definition you say physics offers, is in essence, time is a "process" that allows us to know in the present, what happened in the past, seems more philosophical and value based, rather than an objective definition. Another value based statement was 11.24 "'the light bulb in your home is converting useful electricity into less useful light and heat". Hmm ...Scientific speculation usually avoids like the plague, the issue of purpose. Perhaps that is because purpose is a subjective value, rather than the impersonal objectivity science aims for. But how knowledge and science is understood and utilized, IS very subjective. The light bulb which allows for heat and light (perhaps to read and study by) is utilizing electricity for a purpose, which actually gives electricity more value than just electricity without purposeful utilization. Although we know what electricity is, we don't really see electricity - we see its effects. Time is similar; we see it's effects, not time itself. What if personal utilization of time, is what gives time it's value, rather than assigning it as a "process" of drudgery, such as measuring it from point A to B, which informs us in the present, how long it took a piece of fruit to rot in the past. An objective truth is: for each person, time subjectively flows forward, from the point of one's birth, to point of one's death - and how one spends and utilizes that measure of time, helps determine it's value and importance, more so perhaps than deciding it's as causality or not, as related to quantum theory and entropy. When science postures itself as considering analytical speculation it's supreme goal - ignoring positive purpose and utilization of it's powerful discoveries - abuse of power can fill the vacuum left by absence of proper use of knowledge which yields power, and proper ethical considerations. Oppenheimer in a reflective moment after viewing the first atomic bomb detonation, quoted Krishna in the Bhagavad Gita: "Time I am, the great destroyer of worlds, and I have come to engage all people" Time is cyclic, marking beginnings, and endings. Take any point on a circle - if you move forward following the arc, you will end at the same place you started. Following the arc of time in a cycle, from birth to death, the "process" of time marks one's activities of past at the present moment of death - which simultaneously marks the starting of the new life cycle and forward arc revealing the unknown future (but influenced by the past (karma) according to Gita philosophy). Described in the philosophy of the Gita also, is the explanation that conscious energy never dies, it simply changes form. How to get free from the influence of time and the cycle of birth and death, is also discussed by OG Sri Krishna ;-) Lastly - although used and originating in a different context, a trending slogan as of late is: "Future proves past." Hmm... Food for thought on many levels. Thanks. 6 Reply 1 reply WP Randall WP Randall 2 weeks ago You have to know the basic secrets of reality to know what time is.

So the quantum future collapses into a classical past when observed via the present. 7 Reply 3 replies Star 42# Star 42# 8 months ago (edited) it's common sense to think we can't go back in time , but we are catching up to the Future .let's Go,Time is fluid also 1 Reply Geordie Jones Geordie Jones 2 months ago (edited) I've been thinking of time as the accumulation of information as of late, much like a sanddial, and I would assume that organic compounds especially in their beefy arrangements increase that burden on the universe and maybe its carrying capacity. Everyday we stand upon the buried mass of time on our planet, which slowly breaks down into recycled compounds that fuel our future ambition. I think there's some relationship between energy, gravity and information. The conservation of causality does seem rather inflexible, but its not like we haven't completely abandoned older ideas in favor of better findings. We as humans can very much affect our own perception of time too. Maybe the universe's acceleration is a response that matches our own. Looking at our planet to understand the greater universe is something that still feels very valuable.

Time to me is literally space, to move or to do anything you need time and space together. Reply Eric-Jan DeNooyer Eric-Jan DeNooyer 1 year ago My current explanation/belief about 'time' is that it's simply a measurement of change (absolute change, local change). Because all methods of measuring time involves some means of measuring a physical object that has a changing position in 'space' (e.g., the sun, a pendulum, the resonance induced by an oscillating field). And so that would mean that 'time' cannot exist without also having a 'space' for things to move through; ergo, 'spacetime'. Further, my belief is that there's only one current moment in time (though things that happen non-locally do take their time to be communicated to other locations). And so, this present single moment is the result of all prior cause-and-effects, and also carries information forward that brings upon some new cause-and-effects (though some events can have their causes chosen, which then offers a different outcome than would have been otherwise predestined). So then, as change happens, the previous circumstances become history/information, and that historical fact cannot really be erased/reversed (though it can be forgotten). Simply stated, a bell cannot be un-rung, and so time behaves somewhat like an absolute value function. But yet, if we don't move through space, we are still moving through time. So, are we falling through time? Or, is something always moving/changing even when it doesn't look like it? And then, if something moves through space fast enough, time actually stops and it becomes as thin as zero, but not negative (to the external observer anyway, if they can measure it). Essentially, dimensionless and timeless. In between these extremes, whenever we move through space, we're effectively taking a shortcut through space & time. The faster we go, the shorter the path becomes (both in space and time). It's like seeing every movement as traveling through a wormhole, particularly when you think about those muons coming in from the upper atmosphere. 9 Reply 4 replies Abiston Services Abiston Services 9 months ago Time to me seems simple,if everything is static (no movement of say light or a quark) therefore time stops completely, which i suppose the universe always has movement as what would be the point of existence.

As it touches the singularity state the next big bang will happen and eveything will start over again. The life of the universe will play out again exactly the same as before.

And many other aspects of reality as well as things found in nature. It's possible that time is fractal in behavior because it follows patterns broken down into smaller versions of itself. For instance, we are able to break it down into smaller and smaller units of Time for instance an hour is 60 minutes, a minute is 60 seconds, etc. It's a weird thing to describe as fractal because it can't be seen physically but it's felt and monitored. Other aspects would be how motion in time is just like a video. Frames of time one after the other, making one collective flow of universal actions & occurrences, and those actions/occurrences collectively become smooth dynamic motions of time as we experience it in a linear way. Our behaviors are fractal in nature, we pick up habits and then those habits become regular patterns in our lives, we got to the same locations at the same times (work/hobbies/business, etc) it may be a little different each time but the occurrences are usually the same. You follow the same behaviors. Consciousness could also be fractal, we naturally interpret fractals in nature and that could be why we find them so fascinating. We have physical structures within us that are fractal. For instance, in the lungs, nerve branches, blood vessel branches, our heartbeat is fractal. It beats so many times in a given amount of time 1 minute for instance but follows the same sequences and beat delay patterns. The only time our heart doesn't beat in a fractal way is when there is an issue with it.

Reply 1 reply Malcolm Spark Malcolm Spark 11 months ago Time and gravity are two big mysteries. On gravity I like to think it's similar to behaviour in, say, a beetle. Looking at the atoms in a beetle will not give you the behaviour of a beetle, you need a whole beetle before behaviour emerges. Similarly you need a whole universe for gravity to emerge and if this is correct then there is no point in trying to find gravity in sub atomic or quantum particles. Maybe this is why quantum gravity is proving to be such a tough nut to crack. My understanding (before this excellent video) that time is simply the change of one part of the universe with respect to another part of the universe. In other words it's not something in itself, something that you can do experiments on even though every experiment involves time.

As long as it s alive it has a low state of entropy and possesses a high amount of information. (Note: By the word "information" I am referring here to the instructions needed to keep that organism alive and functioning.) When it dies, the entropy of the organism increases and the amount of information it possesses decreases. Also, his use of throwing clothes onto a chair in a orderly room is flawed as an example of an increase in entropy, because the clothes are introduced from outside the system (i.e., room) so it is not really a closed system.

Therefore, time would be truly relative, as the speed of movement depends on many factors and thus can be slowed down or accelerated.

B is deflected and hits particle C. Two distinguishable events happened for B, one was "first", the other one "after the first" -> time has passed. If we reverse the velocity vectors of these particles, then everything happens in reverse order: C hits B and then B hits A. But even now, the hit-events for B happened in a sequencial (albeit reversed) order: time has passed. You can reverse the order of events, but still, one happens before the other and one happens after the other. Time is just the destinction between "before" and "after. It is just an mental interpretation or concept when we observe the increasing entropy. It is no physical concept on it's own. The time component of "spacetime" is then also a bit misleading. Time is rather an emergent feature of entropy - and entropy requires space to happen (to allow energy gradients which are needed to make anything, including entropy, happen).

The diagram shown here represents a sub-component of a more complicated multi-diagram for a more complicated process which isn't fully shown.

I actually have an idea. On the one hand, it is based on GR, but also on the general observation that systems tend to assume their energetically most favorable state. Especially quantum mechanical systems! When the universe began it was very small, its space-time was highly curved. This can be interpreted as an energetically excited state. Then one could also assume that this geometric state also tends to adopt an energetically more favorable state. The energetically most favorable state in GR is the flat Minkowski space, if you ignore any unsharpness for the moment. On the other hand, starting from the flat Minkoswki space, energy is required to get a curved spacetime. This COULD cause the irreversibility of the flow of time! But was is time? I only see one possible connection. This global reshaping of the space structure from higher to lower curvature does not presuppose time, but conditions it. This constant "structure flow" IS time. One might ask how this could have happened. If there was a primordial, "structureless", only from quantum fluctuations shaped pre-space-time, pure coincidence could have led to the fact that at some point there were enough of these fluctuations became coherent, mutually reinforcing, collapsing, and then expanding. To ultimately come back to drown in the space-time "noise". And this could happened in all possible sizes at any "time". If "time" doesnt exist you have a lot oft it ;) I don't think it's impossible since the Universe, when it was at Planck density, was about the size of a proton, so this coincidences could have happened. The pre-space-time noise was then, so to speak, a chaotic, unregulated flow of time in any direction. My overall thesis then probably also combines ART and quantum mechanics to a certain extent.. Or?

This fits with the laws of thermodynamics dynamics and entropy. As this happens all around us and everywhere it creates an illusion that time is a constant (linear) and that we travel through it. Time dilation can be explained by the amount of interactions (energy transfers) in a given space being relative to the density of that space. In space time would slow down as there would be less interactions of energy as there would be on earth (more interactions) You mention in the video that we live in the moment and the past is created by the present and the future is still a probability. If a wave function had three elements to it, a past, present and future wave, would two (or more) future waves determine the present wave.

Time organizes randomness, heals hurts and gives us perspective. Without time we would be lost, and yet, the best music, poetry and art seem timeless, and we cherish them. All of the world’s great religions assure us there is life after death, and springtime proves them right, most of the time. Time is a kind of currency. Each of us saves it and spends it according to our needs and wishes. My time is not exactly your time, even if we agree to meet at a given hour.

Best explanation of time ever. The reason Newton's laws of motion work at all is because they describe what happens after the collapse of the wave function. Stated another way, Newton's laws describe the position of a particle accurately only when the probability wave function is tightly squeezed together, i.e. with little variation. Where Newton's laws fall apart is when the probability function flattens out, so the probability function is now spread out and not as well defined, for example where there are competing gravitational fields. And that is why Newton's laws predict the future in some systems pretty well, but fail in other instances. Time has nothing to do with it. The probability function is everything. 8 Reply 1 reply Kekukuna Irvine Kekukuna Irvine 5 months ago How does the knowing of information in the known past influence the future possibilities?

Reply Mike Cody Mike Cody 6 months ago Okay, since you asked, here's my theory of time. If we think about what is suggested by the Big Bang, that the universe was started as some event, for the purpose of discussion we will call it a Bang. This Bang represents the idea that something was generated or came into being that was not there previously. Now, what if that was not a one off event? What if it kept happening over and over? Each time it happened everything that had been created in the previous Bang was completely recreated but just advanced slightly. Every single thing from the quantum level to the largest structures is just slightly moved forward in one way or another, including entropy with each Bang. The rate at which this is happening is so fast we cannot detect it. This rate I call the speed of Time. The speed of light is not the fastest thing, the speed of Time is. I don't have an explanation for why this would be happening, it's just an idea to explain what the basic nature of time is.

I already have my own theory on Black Holes and what they really are--based on a conversation I had with a JW. Apparently Hell/The Abyss/Limbo might actually be in the same place, but not the same thing. The event horizon is where time stands still, or Limbo. The black globe is the abyss, and beyond that is what I call a Kupina Star (Blackberry Star). When the energy of a collapsing supernova is enough, it creates a bubble outside of our space-time. This extra dimensional bubble would have the inside of the new star (essentially Hell) on the outside of the bubble, and the outside circumference on the new star would be centers around the infantismally small rip/hole in space-time. The amount of energy (gravity) pulling from a star's field through such a strong hole would create an effect strong enough to trap light. When information falls in the hole, it goes through a reactionary process, and as a result new information (cosmic radiation, etc.) gets emitted out of the poles of the Blackberry Star's center. You could call this process something like "Cosmic Nucleation" or something else weird like that; I wouldn't know what to call it--I am not a physicist.

Which is past, present or future is based on the perceived in time. * The present is the only truth, a chance to wield our brush to paint our reality. * All in d present wielding their brush and it collectively creates a reality both in our present and also in our past & future. * It's a continuous cooking..a continuous painting. * I see this like an audience of 1000 watching a movie in hall and the collecti e emotions of movie changes the the story, flow and characters of the movie of no climax..or if at all one, the climax is what the 1000 together painted. * I also perceive this as a huge endless lake of time, where I exist to perceive a part of it with limited vision of the lake. When I throw a stone in the lake, the waves does travel to every part of the lake even beyond my sense. My lake too is continuously been fed by waves from past n future. * Our free will does not only allows us think and act. But I believe after every NOW, we choose our next NOW in which time dimension. WE ALL FLOAT IN TIME AND KEEP CREATING NEW REALITIES OF TIME WITH NO PAST, PRESENT OR FUTURE..NOW is all that we have... No guilt..No worries..No fears..but live in the moment and spread love..

All I can tell you is that for a moment, only a second or two and for whatever reason I saw clearly how all time existed at the same time & understood it! Well, anyway just wanted to share. Now I'm back to searching for a village. 1 Reply Kostas Hatjiemmanouel Kostas Hatjiemmanouel 1 year ago Beautiful explanation! Entropy seems to be the answer to most of our questions about the universe and our existence! Well done Sir! You remind me of my favourite lecturer at university. 1 Reply 1 reply Brian Parnell Brian Parnell 1 year ago (edited) YES! YES! THIS is what I've been wrestling with and trying to realize!!! Time doesn't actually exist but change does. I'm not really in agreement with this particular concept after that point. Smolens showed the the future is quantum and probabilistic (can't exist until it's measured...and there's the M-word) so it doesn't yet exist and won't until it is experienced, and the 2nd LOTD (Entropy) shows the past can't exist. Every quark that made up every particle that made up every atom of every "thing" has since moved on and there are no "slices" of The Past containing all the little pieces of everything (everywhere) that we can look at or go to in way. It's gone, forever, and instantly. Only the "moment", the instant of Quantum Decoherence is what we experience and the successive experiences of those never-ending moments is what we call "Time". Add-on.... this would also mean Time Travel is impossible, and that Time Dilations which we measure using our clocks (machines to represent time, not to measure time) are perturbations of the quantum Time Field (Superpositioned, static, ubiquitous) and are based on velocity of travel through the field and likely not the mass of the traveler. Time is not gravity and the passage of time is merely a construct of the human memory. Without memory there would no sense of time passing. ...at least it seems that way to my simple mind. 5 Reply kalinthecity kalinthecity 2 years ago I really like Arvin's videos.

Interestingly enough, all the questions that are brought up are answered through other things that you mention. For example - memories & information. Except that we refer to our own memories, but actually the universe itself contains all the information within it. We can attain knowledge of our previous states through a sort of “information trail”. I know that sounds a bit like science fiction, so I will further elaborate: There are 4 stages of development in the evolution of matter, & Imprinted within each emerging stage of development is information about the previous stage; beginning with the simplest to the most complex - and they are, the: Still - which include astronomical bodies (planets, moons, stars) and geological landscapes (mountains and hillsides etc.) vegetative - which includes all vegetation and plant life. Animate - All animal life. Speaking/ Human - The final stage of development of matter and the central point of creation These 4 stages of natural development correlate to the 4 stages of development of desire in man: Still - The desire to sustain the self and keep its form vegetative - The desire for movement and growth Animate - The desire for food, sex, family, Speaking - The desire for power, wealth, honor, fame There is an additional stage of development, and that is the desire for the spiritual (or information about the meaning of life). This is precisely the purpose of consciousness, and why mankind is the central creation. The purpose of this body is to fulfill its higher purpose. For the individual to discover the meaning of life, there must be a lack of meaning. In other words, first there must exist a deficit. Then recognition, perception and awareness can arise from the lack (empty space). The ability for us to perceive already indicates an incomplete state. If we existed in our complete state, (the singularity) there would be no purpose for our existence or for this world, so in fact everything exists only for our sake. This body exists solely for the purpose of attaining its root form, prior to clothing in matter; and only while we exist in this body can we realize our unique role in the purpose of creation. Prior to the creation of matter, we existed in our complete state, the “singular state”. This is the root of creation - The Source . The Source is considered the first matter. We never attain the source. It is an entity that has shed its previous form in order to take on a completely new form; that of matter; the cause of which is destined to be revealed at the end of that formation, and is therefore considered the Primary Cause (Existence from Absence). We exist in an era where we have collectively undergone enough changes (enough time has gone by). And this era is called "the Last Generation". obviously not literal, but it means we are reaching the end of the human stage of development, and all the information we've acquired throughout the evolution of the universe exists in a form where we can transition towards this integral consciousness and perceive this infinite unbound state that was (prior to the creation of our universe). Now of course there are laws to this "conscious frame-work", and it's not quite time yet (the effects of entropy are not fully manifested), but very soon I think that we can consciously and collectively break free of our limited state. 2 Reply Pulkit Acharya Pulkit Acharya 1 year ago This guy is good ...I mean real good.So many aspects of nature explained in a jiffy...Loved it.Finally since 2006 getting something good. 1 Reply Siloe Noah Siloe Noah 2 years ago i’m 15 and am inspired to become a great engineer/inventor one day.

There could have been something and a timeline before the big bang but we simply have no evidence of it. I think you alluded to this in the video. Reply 2 replies Wittgenquine Wittgenquine 1 year ago I enjoyed the video. However, the relativity of simultaneity depending on reference frame is usually taken to be near conclusive evidence for the eternalist/4D-block theory of time. I am confused why you didn't discuss it. If according to relativistic physics what events are occuring simultaneously is relative to your reference frame, then there can't be an objective 'present' moving from past to future which rules out the other three theories of time (i.e. presentism, growing-block, and moving spotlight).

Reply kathrynck kathrynck 1 year ago (edited) I think it's helpful if you imagine the universe as a single point, moving through a 'probability field' in a newtonian fashion, unchanging unless acted upon by an outside force. Or perhaps more accurately that a consciousness is a point thusly moving. And that at any point an 'awareness' (not a predictive guess) of future experience presents a leverage point upon which this motion would be capable of diverting the newtonian path, although that would require the application of force on that traction point, not just awareness. But that gets into a pretty thick briar patch of causality violations, which is where things start to get really complex, and the use of a simple block pattern starts to look like a much too simple analog.

As a child I used to annoy every adult around me with the philosophical Socratic depths no 4 year old around me could entertain. “Why didn’t the year 1994 come around like the month December?” My 3 year old self queried my father on the New Year’s Eve of 1993. It baffled my mind that we had multiple December-January, we had two 6pm/am et al, Monday- Sunday repeated.. but we would never have another 1993. He explained the concept of millennium, decades, centuries etc. but I had to question when we would get another 1993. It really did not ever stop until I annoyed my teachers and got bullied for my adhd & gifted IQ. So I started reading my parents old encyclopaedias in depth to satiate my thirst for knowledge, and one thing I read early was a quote by a philosopher saying “time does not exist but only clocks exist”. That was annoying when my maths class went through units of measuring time, it was frustrating for me after I hit adult academics only to learn about the methods of philosophical error and enquiry. Thus far, in 2022, I have expanded my knowledge of topics like psychology, neuroscience & anthropology. I have a secret affinity for the weird metaphysics of quantum physics. I would never be able to academically apply this interest yet I still have the perplexing notion of time as a construct. A book called “timekeepers” was a brief history of time measuring before I hit a point of the Greenwich point and the law in Caesar made, making it illegal to have no two clocks that were different in France in the beginning of that calendar and clocks. Any clock that was wrong was illegal. then I felt deeply frustrated with the depth and lack of cohesion of the history and mythology of the mainstream academic world. I felt the same sense of nihilistic and existential dread that this topic induced within my perception; because I find my happiness in my studies, education and applying that skilfully to build a life of meaning. When I dive into topics like this make all things learnt void. I had a lot of deep self work that i went diving into my soul seeking a purpose when I felt a depression and trauma in my late teens. I did a lot of drugs. I pulled myself out and went through a long therapeutic self enquiry learning how to become a productive and healthy adult. But now years away from my drug fuelled teenage years I listen to this and I recall that vague notion of how I felt when I took a lot of psychedelics and the hopelessness of singularity that was pervasive.

How about if the illusion of time is in reality the equivalent to a running backwards entropy? Because it gives the illusion that the farther we go, the farther we are running away from the entropy... Reply courag1 courag1 1 year ago If past, present and future happens all at the same time, then time travel isn’t going anywhere in space, it all happens in the space we are in, according to what you are saying. If our solar system and our planet is chasing our sun madly as the sun is moving through the Milky Way. If we were moving in time to arrive in either the future or the past, we’d have to calculate where our planet is and where the spin is on our planet for the specific time we’d hope to arrive. If our error was very big, we could appear inside a mountain, under the sea or out in space and be dead. We’ve seen time travel movies such as the Time Machine or Back to the Future. In those time travels in the exact same space. It is as though the Earth is flat though it may appear round and spinning. Whether we like that term “Flat Earth”, it is more understandable in time travel in that our space does not change, we are just Fast Forwarding or Rewinding right were we are. How would we have the power to control space and make all space static just for our benefit? We could not even travel then around the sun as we could again arrive where the planet is no longer and be dead. The sun and all the planets, and galaxies, would be revolving around us. The observation of the stars in their great distance would not apparently not alter much as this is how we’ve always perceived them. If one an explain how we would arrive on an Earth hurling rapidly through space to keep up with the sun, then you can have time travel through space. But it appears we aren’t going any where. That there are some indications that some do know the future or have replaicated what the future will be like, as in Angkor Wat temple, how did they do it? To travel far into the future or the past if the world travels through space, without wormholes in which you are instantly there, we’d die of old age and not be able to return in our lifetime.

Thus, in his sitting in the park, a choice to sit on the right or left side of the benches creates a "split" where different things happen to him depending on his choice to sit on the right or left side. Then for each instantaneous inkling of choice from either position split off into other universe probability branches forming a "fractal esque" 5th dimensional universe.

What is your definition of Consciousness and why do you think it began with the big bang. Einstein also said that "nothing is created, nothing is destroyed but everything is transformed" thus infinity cannot be contained in a dvd. Consciousness is everywhere at the same time because there is no time. What we perceive as past, present and future is because of consciousness temporary experience as an individual self, thanks to the human brain which stores information and creates a persona, an identity to experience life as if it were separated from everything else. However, people who have had near death experiences or who have taken psychedelics, ayahuasca or sapo, have experienced a completely new state of consciousness where they no longer feel separated from the light source which sustains all life. A state where past, present and future happen at the same time, a place where there are no mysteries nor secrets, a place described as pure love and light. Evidence of this is that people from completely different backgrounds, walk of life and location, all describe very similar experiences. Like in some sci-fi movies, it seems that a sparkle of that collective consciousness gets temporarily incarnated in a sandbox (like you would when testing a new program in a computer), a virtual reality which we perceive, thanks to our senses, to be a 3d world while in actual fact there is no such thing as matter. Particles are vibrating at a certain speed giving us the illusion of solidity, however particles only change their behaviour when observed by consciousness. Thus, in this reality, what we believe to be true becomes true because our consciousness is manipulating matter to ensure that our experiences match our expectations of reality. 🌞🤗🙏 Reply interloop interloop 3 years ago I like it when science catches up with my thoughts. 6 Reply Alexis Palmero Rodriguez Alexis Palmero Rodriguez 1 year ago What does relativity and QM say about the duration of each time frame in the block universe?

What you described, atoms forming, intelligent life (how about heavier elements?), have all happened after the Big Bang (as per average theory). These are not entropy. Only at this point in our perception is everything falling to chaos. We're not that good at clocking the universe yet. Time is what we call our measurement of motion. The object that is 10 feet away is also moving ten minutes away with me, often with imperceptible changes. Those changes will eventually redefine the nature of whatever it is we've moved into someday. The journey will have redefined us as well. None of this validates any notion about us being pre-programmed accidents waiting to happen. I've heard this kind of talk before. Somebody somewhere is trying to sell us a cake and eat it too. If all pre-exists, then learning to like it is superfluous, free will being an illusion in that scenario. I feel more like it's just a fancy way of selling us indemnity in exchange for resignation. I may seem off point here but even if we can't catch planet killers (stuff too big for us) it doesn't mean that our wiggle room amid greater forces is predetermined and pointless. It's conjured conjecture. 12 Arvin Ash Reply Arvin Ash · 9 replies Aryan Aryan 7 months ago Understanding something as a part of it is a very arduous task. We may never know how the universe works.

A theory of a lack of free will would assume that the events (including thoughts, actions and emotions) are fixed unchangeable points in those dimensions, like on a DVD. But quantum mechanics and also most spiritual perspectives (especially eastern and mystical traditions) assert more of a dream-like reality - where consciousness is constantly creating every moment (and even the past and future). If you meditate to the point of getting even a quick glimpse of the "observer" being able to witness thoughts as independent from an "inherent" self, then this makes more sense.

Then perhaps if "entropy" where an emergent property not a force then the arrow of time would also be an emergent property. Gravity seams to be an emergent property of movement as well, mass moving towards each other, can also be mass moving away form not mass this leads to the same conclusions as well. So perhaps we are just asking the wrong questions or we are unable to ask the correct questions at this "time." If Sean Carrol is correct and there are an infinite number of universes then we have already reached max entropy just on a different level, entropy is just another "universal" result, multiple universes being the entropy. 1 Reply Arvin Ash · 1 reply Millennial Seeker Millennial Seeker 1 year ago Is time an illusion?

Past present, and future are manifesting simultaneously in dimensional- mediums of liner time; which are dependant on the awareness of aware, being aware. If awareness is absolutely passive (in observation of) positioned outside of the liner flow of fluid past, present, and future - it{awareness being aware) is able to experience, and perceive, past, present, and future manifesting simultaneously as it flows through awareness being aware. However, under the natural laws of passiveness, awareness being aware, only perceives the simultaneous manifestations of past, present and future manifesting simultaneously - in a State of passive-Aware non-thought. Actively aware, in a State of active thought: allows for only singular presence, in a singular time medium of [past, or present, or future, simultaneously manifesting,] at any given instant as they are manifesting. Time Mediums: [ translucent water, \space that contains natural law(s) potential/; governed under natural laws of fluid dynamics, simultaneously precipitating the manifestations past, present, and future to the awareness being aware], are coordinates themselves, in the liner flow of the light of awareness, being illuminated by aware, being actively aware - yelding to the perception of actively perceiving: awareness]. Final Note: without awareness being aware: Nothing Exist. Awareness being aware "is" the root cause of past, present, and future manifesting [individually and/or collectively (simultaneously).

This is where some scientists can get stuck thinking that they “know” more than they actually do. Very good videos though, I love them - but I would just suggest being cautious not to label a few theories as being the only options. These are just a few possibilities at best, and it’s quite possible that neither of these theories will end up being correct.

Our mental notion of time is due to the human ability to remember previous arrangements of matter or to imagine future arrangements of matter. We really live in an eternal "now" within which motions take place at various rates compared to the motions of the standards we've adopted. Einstein managed to turn time into a dimension and combine it with the other three physical dimensions to come up with an impossible to image four dimensional "space-time continuum".

It doesn't have coordinates in universe. It never even flows. One's brain just captures events into consciousness, thus endowed with conceptual sequences for reference. Universe is changing its states but it doesn't mean time exists although there may be information storage for the state change to be forward-consistent. Likewise, the future is a word for what we call "prediction" only in each observer's consciousness as extrapolation, interpolation, expectation or hope. Therefore, time is a numerical system or symbol(word) to conceptualize discrete time slice of events in any given conscious system(each individual's brain) or computer simulation and the necessity of time concept arises from the fact that the elementary particles of universe are in ceaseless motion. 8 Reply 6 replies José DeSouza José DeSouza 2 years ago I remember bumping into that concept many years ago when I read Kurt Vonnegut's novel "Slaughterhouse five" Reply Down With Putin!

This phenomenon can only be observed by a being who possesses consciousness, meaning God, and only from fifth dimension. Furthermore, regarding the statement that time does not exist, only as a perception (2:27min), this is completely correct. Consciousness perceives the state transition from one third dimension to the next third dimension as time. Further, at 3:07min of the video, the arrow of time is mentioned. And it exists within individual and collective consciousness. Do you notice that the entire reality revolves around consciousness?

And isn't increasing entropy a logical conclusion when probability is taken into account? Meaning: there are practically an infinite number of configurations a system could take that results in increased entropy, while only one configuration in which it doesn't increase and one pathway toward decreased entropy? It's the same reason cords tangle in your pocket so easily: an infinite number of ways of becoming tangled and only one in which it maintains its original, untangled state. That being said, I guess it doesn't answer why the state must change at all, bringing us back to the original question of the arrow of time. Alternatively, I wonder if time could be symmetrical in terms of its directionality. Maybe time flows backward toward the lowest entropy possible in another universe, resulting in a singularity, at which point it inflates 'on the other side,' so to speak, resulting in a mirrored light cone that represents our universe. The reason we experience this side of the big bang may be that conscious awareness is only possible in a universe of increasing entropy because it allows information to increase; a necessity for intelligence. While the doppelgänger universe may be identical in structure down to each individual's life, they're not taking in information about the environment, but expelling it, negating the possibility of consciousness.

This is the first time I heard it said from someone other then myself. It's encouraging to hear, because when I talk about it to other people, they think I'm nuts. The greatest encouragement I got was when I heard that my concept of 4DSpace Time was supported by Einstein's theory of relativity, "time is a distance." To me 4D Space Time is a network of space and time. It's like a computer game that can be seen from all directions. It can be rotated, zoomed up on. It is a solid of 3D objects in space and time. Once an object occupies a space in time it will always exist in that space time and nothing other then that space time can occupy that space in that particular moment in time. I call it drilling through space time. Think of it as a ant creating a tunnel in the earth. You see the existence of the ant by the evidence of the tunnel. However, let's go one step farther, instead of the tunnel being empty the tunnel is actually filled with the body of the ant. So if you were a being that was able to see 4D Space Time, it would look like a network of solid objects in space time and there would be no movement. You would see it as a whole part. Also, we think of the space surrounding us as empty, that's how most people would describe it. However, to me it's more like a solid, a solid of possibilities and probabilities. So as we move through space time, we are like the ant, drilling our tunnel through and leaving the evidence of our existence as a solid of 4D Space in time. So, thanks for sharing the phrase, "4D Space Time" it helps me to know that I'm not alone in my thinking. 3 Reply Moo Tal Moo Tal 11 months ago (edited) What if time stands still ?

Reply Steven Schilizzi Steven Schilizzi 1 year ago Great video as usual. Now I’m wondering. You talked in terms of “the” present / past / future (PPF). What Einstein showed is “just” that there is no PPF on which everyone can agree with high precision. To me this does not mean that PPF “does not exist” (whatever “exist” might mean!) but that it represents an individual observer’s “from within” point of view and trajectory within the spacetime block. For him or her it makes perect sense to speak of PPF. The second thing is that any difference of point of view between different observers is only noticeable for an infinitely precise perception. But our senses are finite and approximate and so no matter how we move relative to each other on earth or thereabouts, we cannot perceive any such difference. So defining a collective now is, yes, an approximation, but a very useful one, and thus a useful convention. We collectively all experience the same now, past & future at our scale, as if all humanity reoresented one same observer with a single trajectory in block spacetime. I find nothing mysterious there. Such an approximation only breaks down at cosmic scales and at high speeds - which is what SR and GR focus on! - Is this interpretation correct or have I got it wrong? Thanks! 20 Reply 9 replies Joseph Lorentzen Joseph Lorentzen 5 months ago If reality is just an illusion, then the future and past are illusions. 2 Reply Joseph Ramondino Joseph Ramondino 2 years ago I just can not express how amazing of a job you do in breaking down complex concepts into an easy to understand explanation.

I studied physics at university, but never formally got to general relativity. I tried to learn it on my own several times, but always got stuck on tensors. I think the reason is that I always learned in the past by seeing examples, but tensors are so complicated that I suppose no one wants to do an example problem. So I'm just supposed to see the definition of the most complicated math I've ever worked with and understand it without seeing it applied. Anyway, my tested IQ is 133, and the border between special relativity and general relativity seems to be where I get stuck. I just have to listen to the dumbed-down intuitive understanding from the people who do understand it and take their word for it. So, do the physicists/mathematicians at the cutting edge of science have IQs of 145? What if there is a guy who has an IQ of 180 who has solved all of our current problems, but no one believes him because they cannot understand him? I do believe for theoretical reasons (coming from the first mover argument, Goedel's theorem, and the Entscheidungsproblem) that it is not possible to find a theory of everything. Probably in order to truly have a complete understanding of everything would require an infinite number of logical steps. If that understanding is correct, then there will always be an edge of physics that can be explored by the scientific community, limited by the IQ of that community. 5 Reply Facundo Marino Facundo Marino 1 year ago LOVE whenever physics and philosophy meet 520 Reply 74 replies Hi!MyNameIs!

Reply Iambent Iambent 10 months ago 9:44 I’m trying to wrap my head around the spiral shape that emerges in this animation collapsing all the possible time slices into the ones with the largest tilt sweeping out the light cone for an observer. Things popping up in my head are the observer effect, the double slit experiment, entanglement, time dilation and length contraction relative to light speed, the arrow of time implied by entropy. I feel like all of the above are implied within that single animation, and the reference point of the observer into which the light cone disappears acts as if it’s a singularity of consciousness. If every observer (be that a single particle or a collection of particles in the shape of a human being) can be defined as an entirely unique data point acting like an index of ever so sligtly differing angles of all possible time slices leading out of (or into) it, it may very well seem from that vantage point as if the only tangible thing is the present, surfing on potential from the past and propagating itself into a blanco future. So, even if past and present and the now are all already there in some sort of static block universe, and each point acts like a needle on a vinyl record, there is one problem that remains standing, and that is that the way those time slices seem to unfold from each vantage point seem to do so along one axis. Let me put it another way from an information theory perspective: if everything in the universe behaves like fractal feedback loops, you can imagine spatial dimensions being like intersecting branes, forming somewhat of a closed loop in which spatial features can inform eachother from n points of space over 1 of time, whereas timelike features can inform eachother from 1 point of time over n of space. The time dimnsion, in contrast to the space dimensions, acts more as if it were an open brane that does not close back onto itself to form a closed loop so it cannot inform itself about itself. The clue of the story: we have but spatial features to track and map their evolution along a time axis to become aware of the concept of time, causality, past and future. It is only in mapping out those spatial features along an axis of time that those concepts take on any meaning. We are but prisms of the cosmos, reflecting itself into the caleidoscope of consciousness. 1 Reply Chris Auten Chris Auten 1 year ago All this portends the very real possibility of other life forms that may have discovered how to travel through time and perhaps we humans may be able to do someday.

I love stuff like this, very fascinating! Good work 👍 Reply Tristan Laguz Tristan Laguz 2 years ago As always, a truly great video 😀 👍! I’d like to ask about three things: 1. Relativity theory doesn’t really rule out an absolute, universal time, does it? For example, Antony Valentini in effect says on page 4 of his paper ‘Subquantum Information and Computation’ (https://arxiv.org/pdf/quant-ph/0203049.pdf) that quantum non-equilibrium may allow sending signals in an eyeblink through entanglement, and that this would define a preferred reference-frame whose clock measures absolute time. 2. I believe that it must be true that the past, and at at least all possible futures, are equally real as the present, and that the flow of time is due to presentness moving along that fourth dimension. However, what time passes as the physical present moves through physical time? After all, movement needs time. The same can be asked about the second and all higher time dimensions, leading to an endless regress. In his books, such as ‘An Experiment with Time’ (https://www.fadedpage.com/showbook.php?pid=20181016) and ‘The Serial Universe’ (https://archive.org/details/serialuniverse032783mbp), John William Dunne uses this argument to show that there must be infinitely many time-dimensions one after the other. John M. E. McTaggart likewise realized that true time must be regressive in nature, as he explains in his work ‘The Unreality of Time’ (https://en.wikisource.org/wiki/The_Unreality_of_Time). But where Dunne applies modus ponens to show that there must be an infinite time regress, McTaggart applies modus tollens to conclude that time is unreal. 3. Why is only materialism pitted against solipsism? I myself, for instance, believe in an external world (though I’m not 100% sure), but I’m certainly not a materialist. Rather, I’m a platonist, and I see modern physics corroborating my arguments for everything being based on information and abstract things. 4 Reply Marcus Carana Marcus Carana 7 months ago The channel Physics Videos by Eugene Khutoryansky did a simplified way of illustrating how the perspective of time is different for each observer. Check it out on his channel if you want. I personally like his Einstein's relativistic train video.

Reply Edward John Freedman Edward John Freedman 1 year ago Might the "now" moment be how decoherence is expressed in the time dimension of space-time? So, in space we experience solid matter (as opposed to the wave it emerged from) and in time we experience the "now". The implication would be that time is emergent from mass, not fundamental. Also, the arrow of time would therefore be the result of our continuously expanding universe, which in turn "stretches" all matter, which in turn generates a continuous flow of new "now" moments. Another implication of this way of thinking is that entropy is the result of our expanding universe. 27 Reply 3 replies Anharie 1 year ago according to terry pratchett, we are traveling backwards through time. since you can "see" the past and not the future, but are traveling towards the future regardless. what a man 3 Reply ami holonou 10 months ago If that's accurate it'll mean there's only one consciousness which has already experience & documented itself in every possible ways 😶 Reply George Flitzer 11 months ago My concern is it’s not just science but spiritually as well.

Why can't the two observers account for the differences in their positions and velocities to get the same map of the past? Is their an intuitive example that can be given, or is this something that falls out of unintuitive math? (It seems to me that "now" is often confused with when something is observed vs. the observation plus the time it took to reach the observer.) Towards the end of the video, it is suggested that QM is also required to explain the concept of now, but the explanation up until then relied on relativity.

Rather the closest thing to a time "line" is one that each and every living being has (let's just go with humans to make it easy), as opposed to each and every one of us existing on the same time line. To make it simple, right now as I'm typing this comment up, it is happening in my own personal time. But for you, the viewer, you read it 20 years ago and for you, your current "present" is actually 20 years in my "future" just as some old hermit who's living in a cave in some far off country in YOUR present, may be physically existing and doing/thinking whatever it is they're doing/thinking except that for him, he hasn't consciously existed for over 80,000 years. A simpler version is: To me, the Lincoln assassination happened almost 200 years ago but right now for Abraham Lincoln it's 15 April 1865 and he's just sitting down in his seat to watch the show. In other words, reality exists, but we as INDIVIDUALS are only experiencing it at our own pace and unless there are at least two people consciously existing at the exact same time, then despite there being almost 8,000,000,000 people on this planet, we all truly are alone.

Regardless of what we experience or perceive from a relative standpoint, the components that make up the universe have a unified state that transitions from one moment to the next. One can say for example that a software program simply exists, but if the code is running, the program is perpetually transitioning from one state to the next, as long as it is functioning. The universe could be like a pool full of water that sloshes around in an endless loop. If the loop unfolds and repeats the exact same routine, then maybe then, the present, past, and future would not exist. It would be like wheel that spins forever in the exact same way.

One time "tick" is essentially one interaction between 2 or more particles. (Which would also mean that looking at time as past, present and future is kind of meaningless as only interactions exist) But if time is a consequence and doesnt exist outside more than 1 particle, how can there be a speed limit for 1 single particle?

If you move a distance per time, you could say you used energy to move distance, or used energy^2 to move faster. Also, what happened in the past is just how our brain has evolved to understand sequences. This is useful for humans, so they can learn. Saying that, you don't need to say it happened a certain time ago, because time is irrelevant. It happened in the sequence of movements where you used energy. So all your past actions can be explained by energy instead of time. Going forward, this means that space time does not exist, only space and the energy you need to use to move distance. 5 Reply 8 replies pyroflea pyroflea 4 months ago (My entire understanding of this is from these videos, don’t come for me but ) Does dark matter replace time?

Reply Ben Jackson Ben Jackson 2 years ago One brain-twisting thought I had about this "block universe" model: If, as the model suggests we exist on one razor thin slice of time then if everything were to suddenly stop and everything became frozen in its current state, we would have no way of knowing if that is the case. We only get the sense that we are flowing through time because the momentary state of our of our short term and long term memory. If all matter was suddenly frozen for some reason, then these states would be frozen too. It's a difficult concept to articulate but basically I'm saying, it is impossible to distinguish whether time is flowing as we think or whether everything (energy, matter, etc) has frozen in the current state (possibly for millions of years...) 4 Reply 5 replies Patrick Thibaut Patrick Thibaut 1 year ago Great animations!

The change in movement from moment to moment is what we perceive as the passage of time. No movement, no time. The future, unfolds from a “bank” of probabilities (I call it semi-deterministic) towards an “end”, for my purposes, heat death. Now, there are different roads that all lead to the same conclusion (which is why I say, semi-deterministic.) Anyways, as entropy increases, the amount of probabilities for energy to move in the universe decreases, becoming more “predictable” as probabilities decrease. My oversimplified version of explaining time in reference to entropy, is a snow globe. Shake it up, a lot of movement and change of movement, as “time” progresses in relation to entropy, the particles all fall to the bottom until, “heat death” or no more passage of time. Unless energy is put in or we are in a false vacuum, no more probabilities exists for energy to move. 1 Reply kilroy987 kilroy987 1 year ago That depends.

But, these past present and future of the hand wave can be much shorter than the past present and future of my actual hand. If I make up a melody but only play it in my head it's past present and future is much different if I hum it, play it on an instrument, record it and it is play several times and hummed by other ect. The melody's past, present and future is much different. Action as a big impact on PP&F. Time and matter can not exist without each other. Time and matter, from the beginning in in a state of now till the end. Matter itself can change form but continuously exist. If matter turn to energy, the energy exists nd expands outwards like our universe is. Sound continues to expand. It may seem like it eventually disappears. The frequency is so spread out that it is not observable to us. Movement, action, reaction creates pp&F and observation. Without observation, It just is.
