More than just the interesting physics and philosophy topics, I was fascinated by how well they conversed together. They clearly listened attentively to each other, connected on ideas without talking over one another, and had a smooth, engaging back-and-forth flow. Their respectful yet vibrant exchange of perspectives was not only intellectually stimulating but also a lesson in having a thoughtful, enlightening dialogue. Inspiring. 42 Reply 2 replies @1PrinceWilliam @1PrinceWilliam 1 month ago Brian Greene and Sean Carroll together at last?! Yes please, and thank you! 181 Reply 13 replies @stellarwind1946 @stellarwind1946 1 month ago Wow what a treat to have these two together. Two of the brightest and most articulate communicators of hard science. 101 Reply 4 replies @MrBendybruce @MrBendybruce 1 month ago I mean, two of my all time favorite science outreach educators both together on the same podcast. What's not to like? 67 Reply 1 reply @Seb1066_ @Seb1066_ 1 month ago This was so good. Two great scientists and scientific communicators grappling with some big themes. I loved it, thank you both 22 Reply @jimmydoolitle3764 @jimmydoolitle3764 1 month ago Absolutely brilliant. Fantastic that Dr. Greene provides the opportunity for the audience here to learn from the greatest minds of our generation. I always watch, listen and learn. Sean Carroll is one of my favorites and these two together are definitely a treat. P.S. for Dr. Greene. Lenny Susskind is one of my favorites too. I am a nuclear and electrical engineer by profession and I took the time to watch Lenny teach QM on video from Stanford. I really enjoy it when the two of you get together and I especially love his Feynman anecdotes. Please do something again with him soonest. I have watched everything you and Dr. Susskind have done on YouTube. 28 Reply 2 replies @p__b__3749 @p__b__3749 1 month ago My two favorite physicists (so far). Loved them in Sean's Mindscape podcast. These two talking about their field of expertise will never get boring or old. 3 Reply @user-he1yb7pl1w @user-he1yb7pl1w 1 month ago Love Sean Carroll, we are lucky to have him in the science community. He has a fantastic understanding of all the models and I love how he can explain things clear and concise. I'm one to believe that we could have Many Worlds and CCC both be partially right. I don't see why there couldn't be Many Worlds as well as Cyclic Cosmology. Both really explain different things. Many worlds explains Quantum weirdness and probabilities and CCC attempts to explain the start of the universe and end. 1 Reply @harapriya369 @harapriya369 1 month ago Brian Green my all-time favourite scientist not because of scientific temperament but because of his enthusiasm and passion to teach the World 🌎 This show actually justifies the name "World Science Festival " because real Festival is something that is not limited by a closed circle or group rather it is being celebrated by the Whole World 🌍 This show encourages the World scientific minds. It's great 👍 Both the Cosmologists rock show🎉🎉 9 Reply 1 reply @ralphhebgen7067 @ralphhebgen7067 1 month ago These two guys are my favourite science communicators - I attended Sean’s talk at the Royal Institution in London the other week and he was absolutely brilliant. What I love about his style is that he tries to make the maths behind the formulae approachable. Of course it won’t replace a university degree but a layperson with some mathematical background (perhaps A-level, college general studies level) will develop a far deeper understanding of the subject than they might get from reading journalistic articles or some of the books in the pop-science genre that are out there. I think Brian and Sean do a great job also in getting young people to study science, maybe those who are ‘on the fence’, who have an interest in the subjects but are unsure about a full-blown university degree. To those, listening to their excellent podcasts and reading their books must be like fanning the embers of a fire. 4 Reply 1 reply @SicilianDefence @SicilianDefence 1 month ago Two legends of the physics community!

I’ve learned so much from you and consider it all priceless! Thank you. Thank you. Thank you! 2 Reply @NicksShred @NicksShred 1 month ago (edited) The only path out of this in my mind, that truly seems to fix the low entropy / early universe problem is something akin to Pentose’s Conformal Cyclical Cosmology, where the scale of the late high entropy universe no longer means anything, and you end up with a point where space ends up naturally falling back toward what looks like another big bang. I know there might be issues with it, but it’s one of the few ways out that could make sense. Brian and Sean, both of your collections of books have inspired me greatly! Much love ❤ 2 Reply @timveseli @timveseli 1 month ago Sean is a great guess.

I distinctly remember learning in school in the 90s that the energy I/O in a chemical reaction was directly determined by the mass difference according to E=mc^2. I guess i had a pretty good science education! 3 Reply @joyecolbeck4490 @joyecolbeck4490 1 month ago Perfect conversation for a relaxing evening of astrophotography.

I could listen to you both for literally hours 1 Reply @HGALAXIES @HGALAXIES 4 weeks ago It's amazing when you have two of the top brains of the history discussing universe! 🎉 Reply @Raptorel @Raptorel 1 month ago I'm so glad that Brian mentioned the idea of very long random fluctuations that, just by chance, at some point end up just being uniformly distributed such that they start inflating: it's been my own idea on how the universe started from low entropy for quite some time. If you have fluctuations (although I'm not sure where this is happening - do you need an already existing spacetime where these fluctuations happen or do we have fluctuations of spacetime itself, like a "bubble" of spacetime with different energy distributions popping in and out of "nothing"?) that happen continuously, then at some point, just by chance, a particular fluctuation will have its energy distributed uniformly and in it inflation will start, expanding that bubble and not allowing it to collapse back. Since the positive energy in that fluctuation can be compensated exactly by gravity with negative energy, the fluctuation will have zero total energy and therefore will be able to live forever (here I'm referring to the uncertainty principle between energy and time). This way, only low entropy fluctations create universes, since only low entropy fluctuations can inflate, they are the only ones for which gravity behaves repulsively. So it's not a mystery why we started from a low entropy state.

Thanks for the words from the ending, i will definitely continue without any care of what others think. I'll come work with you soon! 6 Reply 1 reply @robertkazenel5498 @robertkazenel5498 1 month ago Thank you both so much, I am profoundly grateful for your generosity of spirit. 1 Reply @cheriecica @cheriecica 1 month ago Wow!

So good to see them together!!!!!❤❤❤ Reply @paulc96 @paulc96 1 month ago Brilliant. Realistically, what can I hope to add to what's already been said below / before. I would guess that most of this audience are fans of one or both, of either Brian Greene or Sean Carroll anyway. There is also a Mindscape episode where Brian is the guest. That is pretty good as well - and I'm sure it is still available on Sean's Mindscape Channel. And they have both written some great books - especially in high-quality, popular science for the non-specialist. Many thanks to both Prof. Brian and Prof. Sean. for sharing this enlightening conversation. Please do this again soon, when Entropy is just a bit higher !!

Reply @billyshawjr4038 @billyshawjr4038 1 month ago When you started talking about the arrow of time going in both directions it got me thinking. If we could get ourselves to move "backwards" in time, could that just mean that we stop moving in our own time and just start moving in the forward direction of a mirrored universe? Then when we stop our "backwards" time direction, we're right back at the same time as when started in our own universe? Reply @prakashms9621 @prakashms9621 1 month ago Very interesting conversation by two contemporary physicists. Reply @stephenb3577 @stephenb3577 1 month ago Very stimulating! These guys are my rock stars. I find it amazing that a few brilliant humans are starting to understand the fundamental nature of the universe. Not bad for a bunch of sapiens who share 99% of our DNA with chimpanzees. I'm currently trying to understand quantum gravity and the possibility of a theory that reconciles relativity with the quantum domain. My hunch is no.

We need it ❤ 3 Reply @vhfarrell81 @vhfarrell81 4 weeks ago Sean or Brian: Is it possible, in the many worlds interpretation of quantum mechanics, that the other possible worlds generated by an observation cancel one another out and we are left with only the universe we live in? I ask this based on the Feynman statement that photons traveling from point A to point B explore all possible routes but that all these routes cancel with only the shortest time route surviving. Reply @euclidofalexandria3786 @euclidofalexandria3786 1 month ago Since energy is stored in space that is fractilized at the core, its data unpacking can perhaps be thought of something like normilization, you can probably use Collatz Theorem as well, to study energy unpacking out of compressed fractilized space. Frame dragging is the outer boundary, staggered energy and gaps of space. Reply @glennmiller9759 @glennmiller9759 1 month ago I'm struck by how you two sound so much like my high school friend and me marveling and somewhat debating, in circa 1971, about how the structure of the atom was essentially a tiny solar system. The only minor difference is that that concept is wrong and that you guys are brilliant and we were and are not. Otherwise -- remarkably similar.

What a bless Reply @norcalpacific @norcalpacific 1 month ago They originally attempted to do this interview in person, but the mass of their brains together in 1 room caused gravitational distortions. 1 Reply 1 reply @berg0002 @berg0002 1 month ago (edited) Is it possible that when we look back from the present space and time instance down the rabbit hole into the trajectory to the big bang, we may arrive, not at one single but an unlimited number of big bangs in space? Is it possible that the chosen trajectory into the past rather depends on the countless individual branches you choose in the cloud of branches (as opposed to a tree of branches)? Would that alter our ideas with regard if the arrow of time, ie would it be a sphere of time which leads to countless small bangs, bangs in the order of quantum sized energy fluctuations which collectively, by bringing them all together in an imaginary spot in space time, looks like a big bang with a mysterious beginning out of a singularity? Any thoughts about that? Reply @balaji-kartha @balaji-kartha 1 month ago What Sean does, studying astrophysics and quantum physics and philosophy is what leads to spirituality !!

Thank you so much for doing this! Reply @Va1demar @Va1demar 1 month ago entropy is the flow of energy to a state of balance in relation to the system, so light loses its energy or, roughly speaking, goes out after covering vast distances, just like an electromagnetic wave attenuates over a distance Reply @genghisgalahad8465 @genghisgalahad8465 1 month ago Ah, I wish i had gotten in to ask both of my favorite theoretical physicists if the recalibration or recalculation of the observed and calculated age of the universe is inevitable as part of the refinement of the work of hard physical science? And not a sudden pulling of the rug from under? I tend to think overall the former and thankfully the conversation pretty much covers this overall! Reply @anitareasontobelieve378 @anitareasontobelieve378 1 month ago As a mom in a red state you will never know how much these talks mean to me. We weren't taught JACK about this..and me especially so. My town was so small one of parents were my teachers except for 2 years and they are YECs. They mean well but the misinformation they believe and Pure D Brand Lack of Attention, combined with zero concept of curiosity, and adherence to dogma, made me pretty stupid. When I listen to science communicators I learn so many concepts and can understand more. I'm sure students who can do the math love them, too. Your lack of all bragadocio, humbleness, combined with your degrees, and easy manners, help folks like me that were controlled to the Nth degree, I truly am thankful I can learn a bit. Thanks so much. 3 Reply @enriquejose778 @enriquejose778 3 weeks ago Imagine when reaching General AI, letting this entity run the double slit experiment and confirm if conscious dilemma play a role on the result? Reply @Raptorel @Raptorel 1 month ago Speaking of the big discrepancy between the observed dark energy value and the calculated one, I don't know why we're surprised there is such a discrepancy. We know there is dark matter out there and if there are dark matter fields, then we haven't included the contribution of these fields to the dark energy. If supersymmetry is also true (at higher energies than what the Large Hadron Collider can probe), then these fields also contribute to the zero point energy. So we shouldn't be surprised that we have such a big discrepancy between the observed and the calculated value considering we're missing these contributions. I actually think that maybe we have some symmetry where the value is zero, but the symmetry is broken at our low energy scales and this returns this very low value that we observe (10^-8 ergs/cm^3) instead of zero (this is just a hunch, I wish someone with the actualy quantum field theory knowledge could come up with a model).

Reply @merlepatterson @merlepatterson 1 month ago (edited) Something about the vacuum energy of space causes normal matter to fly apart rapidly (look at the very fast expansion velocity of thruster gas exhausted from rocket launches at dusk or dawn and from the rocket engine bell) makes it seem as though repulsion effects of molecular gas in a vacuum is the natural (dispersed) state of molecules/atoms/ions in a vacuum? Thus the reason the larger the rocket engine bell, the better (even a 1/2 mile wide if it were possible) to increase vectored thrust efficiency in a vacuum. 1 Reply @larscarter7406 @larscarter7406 4 weeks ago Mismatch.

Just think about light. The speed of light is positive, distance is always positive. Distance = speed x time so time must always move in the positive direction. Even though the mathematical equations allow time to move in the positive or negative direction, in reality it only moves in the positive direction.

One is based on the belief the Our Universe is all there is therefore something happened within the boundaries of Our Universe which forced the expansion. The other is based on the acceptance of something existing existing outside of our Universe into which our Universe inflated into and rather than a our Universe being pushed outward it was rapidly "Drawn" outward into the surrounding Void.

It puzzles me and defies Logic, as I understand it. You should not be able to start with nothing and then have something and then go back to having nothing. How is this possible?

They're actually waves. It's a wave of energy that connects the measured particles together and creates the constant of time. It's a lot like the positive and negative convention is backwards in electronics. Your taught the opposite however and it's difficult for people to realise the blunder. The only argument that photons are particles is within the photo electric principle. But a closer look shows that the photon is absorbed by the electron. And that's it. No more photon. It's absorbed by the particle. You can no longer say that the photon exists. It's like, are you a cabbage because you eat cabbage. No, it's cray cray. Someone really needs to clean up science.

Is it in line with current theory to say that at the time of the Big Bang, the universe was in that lowest entropy state? I think it is. But does that mean that as entropy TRENDS upwards over time, LOCAL decreases of entropy can never go below that initial entropy measure? If that is the case, the object currently known to us as the lowest entropy object in the universe, the human brain, must have a level of entropy HIGHER than that of the Big Bang. Would that be a fair characterisation of the dynamics? If anybody shared their insights on this, I’d appreciate it.

At the speed of light it’s length and it’s experience of time would be zero. In other words it would become a 2 dimensional object without the experience of time! Therefore objects with mass require a dimension through which they can move and experience time. Time requires dimensionality and dimensionality requires time.( Is this the true meaning of spacetime?)

I knew I'd thought of it in '07, but I found evidence I had, pre ER=EPR, while watching sn6 ep3 of The Big Bang Theory where sheldon gets help looking thru old stuff,, I saw the line after i looked thru my stuff.. 'm very smart n my subconscious must of known I had yhe paper somewhere. I got 100% grade for semester learning Calculus in high school, and am also diagnosed schizophrenic and voices tell me what is about yo happen in shows, so if I'm not like John Nash schiz. then I'm smart and a real person wanted me to find my paper, either way. In the paper, in my community post, I say the whole universe 'dna to celestial bodies', which is like this vids title, so maybe Sean suggested it because of me, idk.. or it is a known thing to reference,, theory of linked quantum and Relativity theories with examples. Check my pic in my community post. Like yo, guys, i have more. And i can use such in my scifi story "psy v cy" psychics vs cyborgs PvC, and like theory,, if JWST shows we're in a blackhole, then I show how an or the original universe doesnt ER=EPR into or out of a blackhole,, inside a blackhole has more degrees of freedom or dimensions,, but i suggest that such is for fields for forces and particles,, our 4 force fields are how String Theory 11Ds are, we are a hyperverse and outside our membrane aka universe aka blackhole?? is more dimensions as in forces, and in a blackhole is less (the thought about part for blackholes, but hey Susskind says noone knew ER=EPR stuff, but i guess i did at latest in 2011, before him in 2013, so what else did i theorize first). A video from World Science Festival on er=epr quantum wormholes said blackholes 'er=epr' Hawking Radiation, but me.. that is how we could go into a parent universe, then the origin universe does decay but instead grows dimensions as in cyclic universe, and could be dark energy and matter. From quantum fluctuations as HUP Heisenberg Uncerainty Principle and that is still embedded in existence from nothingness (Sean knows nothing, not space. Exactly, space is not nothing, nothing is nothing) for how universe or existence comes about, and yhat is the definition of space as different local spots relative to eachother and different times, nothing is different from the start of nothing as something, me 0 into 1 i stance of 0, 1(0). Then that is soacetime growing and info entropy growing, relative to eachtoher, and then energy and matter grow from space growing in 1(0) instances of space but as a field, which is how and why origin universes grow like cyclic universe theory into having more fields. 1 Reply 2 replies @SandipChitale @SandipChitale 1 month ago (edited) I do not get the reversibility of time discussion around 11:50. If there are two oppositely charged particles near each other, the process of them coming closer or moving away is by definition breaking the law of opposite charges attract. Am I missing something? Even in two billiard balls colliding example the two will be hotter after collision in one direction and not the other. No? IMO opinion, there is a confusion due to circularity between the definition of forward and backward when it applies to time. Time simply has direction, forward, and it is the direction in which before event and after events go - refer to Tim Maudlins thoughts on this. Time is a dimension but a time like dimension at that and is not a space like dimension. The Minkowski metric of SR spacetime tells us that. So SR spacetime is not a 4D object of 4 dimensions that are qualitatively similar but a 3(spacelike D)+1(time liked D) object. And thus the forward and backward notions that do apply to space-like Ds should not be applicable to time-like D. Think of it this way - a +ve and -ve altitude of a place relative to sea level can be a meaningful physical concept. But +3 apples is a physical concept but -3 apples is not a physical concept. The talk of forward and reverse time is just not applicable.

So I think this instantaneous communication between the particles may not have a physical level of communication rather it could be a communication via properties, electrones exist but spins don't they are properties of a particle,so why can't some shared properties exist between them , cosmic speed limit is for existing things i believe, properties are observer dependent entities ,so can it have some wierd properties like collapse of a wave function from everywhere at same time?

It’s a process not a dimension nor a thing. in physics they don’t recognise that process and how they inject it in equations. it’s similar to machine or function. future is more complicated than that. The way they calculate time a a function then inject it again into equations is funny, that’s why they couldn’t recognise what time is through thousands of years. Time = Distance/ Speed this not a simple equation as they think, it has to do with how clocks work too. They don’t recognise why they can calculate time through this equation: Time = Distance/ Speed and its relationship with clocks, they can’t understand the real interrelationship between distance, speed and time. the way they calculate time then inject it later in equations is enough proof that they can’t understand what is going on, they pretend that but that’s not true. current physicists are pseudoscientists those who hide under the cloaks of former scientists! Storytellers and propaganda. I am pretty sure that they even cannot understand why they use this equation: Time = Distance/ Speed and it’s relationship with how clocks work. they don’t recognise the relationship between that equation and cloaks! Time is what clocks measure (so smart)! as to them that’s all, Time is a process not an absolute entity nor a dimension! Basically Clocks work based on that equation: Distance =speed * Time, that’s why Time is relative. and Gravity doesn’t affect time directly rather Gravity affects the measurement tools (clocks).

Reply @aminam9201 @aminam9201 1 month ago W = MG gravitational force vs gravitational acceleration. potential energy vs gravitational potential energy. equivalent principle; the equivalence of gravitational and inertial mass. ,…..etc Everything indicate that the current interpretation of equivalent principle is incorrect: very likely Gravity interacts with each particle independently regardless of its location to other particles in the same object, and that is why all objects fall at the same rate. That’s far better interpretation of : W = MG gravitational force vs gravitational acceleration. potential energy vs gravitational potential energy. equivalent principle; the equivalence of gravitational and inertial mass. Physics needs to be reviewed by real physicists, but this will require a deeper understanding of the foundations of physics.

Shame on you Sean, this is something you should have been aware of. After the developement of Ashketar(?sp) variables several LQG groups calculated that in a cosmological collapse scenario gravity would asymptotically go to zero as the scale of the universe approached the Planck length. It would reverse sign and the repulsive force would grow asymptotically below the LQG scale a ~P.l.^1.6. Hence a bounce scenario is supported by LQG.

Reply @kiabtoomlauj6249 @kiabtoomlauj6249 4 weeks ago Right.... we would just round it off to roughly 68% - 70%, in terms of Dark Energy proportion of what the Cosmos is made off ... even though our calculations show Dark Energy is actually roughly 10^100 more.... Why? 'cuz we gotta allow ~5% of the Universe to be normal matter (of which we, planets, and sun are made) and 25% - 27% to be Dark Matter. Folks, hate to keep saying the obvious, but when facts --- according to the very calculations of the very scientists who keep repeating these IMAGINARY proportions to you (that the Universe is made up of Earth/25%, Fire/25%, Water/25%, and Air/25%) --- keep saying that these "best and brightest" don't know what they're talking about, you should believe FACTS. It's religious, not scientific, when you grabbed exact numbers out of thin air and asserted them to be "facts" (of what the Universe is made of), with the line of argument of: "We are the best and brightest in society (2-5 PhDs from Harvard, Princeton, Stanford, etc)... who are you to question us and our impeccable random number assignations?...

Reply 1 reply @peterdamen2161 @peterdamen2161 1 month ago Interesting to see that both Carroll and Greene have no idea what the arrow of time is, or time, for that matter. Carroll, again, comes up with entropy, which in essence has got nothing to do with time. Time doesn't run backward in your fridge. And let me tell you a secret, the supposed arrow of time doesn't even exist at all. Both Carroll and Greene, like many physicists, confuse reversible, cyclic and oscillating reactions (or laws of physics) with what time is and how it functions. Simply said, you cannot go back in time, which shows that the arrow of time doesn't exist.
