Fun fact is that even some humans have very limited ability to see polarisation - look for "Haidinger's brush". 93 Reply 3 replies Alex Alex 1 month ago without a doubt the most clear, thorough, and engaging science education content on youtube. no stone left unturned, all perfectly parseable. you are a treasure. thanks so much for what you do. 151 Reply 7 replies Daax Daax 1 month ago (edited) $49.99 Thanks for making these.

I asked my physics teacher, and even my dad who studied Physics, but they didnt really know. This video explains it so well, that I understood it at first glance! Thanks! 23 Reply mgx mgx 1 month ago (edited) It would great if you could somehow visualize how a classic EM wave arises from a number of photons of the same frequency, and what it means for a photon to have frequency in the first place.

Thank you. 10 Reply Rationalific Rationalific 1 month ago These videos are absolutely fantastic! I could honestly listen to and watch a ScienceClic video about this for hours... I'm always introduced to things through these videos that I had no idea about. I learned the basic information, like reflection and refraction, but I never learned about their inner workings. And some things, like why the sky is blue, have been answered elsewhere, but this explanation is still unique and gets more into the physics behind it. (I would have liked to have seen info about red sunsets as well... Maybe in a future video...) The worst parts about your videos are when you say things like "Finally" or "To sum up". I just don't want them to end so soon! 1 Reply Book city INK. Studios Book city INK. Studios 1 month ago (edited) He just explained the wave behaviors!! His videos are always amazing.

These videos are always worth watching at least twice. With every video I learn something new, or re-learn something I'd forgotten. Please keep them coming. 3 Reply Mega Mind Mega Mind 1 month ago Wow! I am 50 years of age now and from the age I went to, what was called Middle Technical School or MTS here) I had majors in Chemistry, electrical engineering / technology , physics, mathematics and all. Every major educated their own little part of the whole story and up till now I haven't seen a combined basic explanation like this which should be the basis of all above mentioned majors! Why, because your video literally gives a concrete understanding about the foundation of all that's teached and how all the bits you learn is actually just one basic fact about particles, matter, how this behaves and what follows as a consequence out of this fundamental behavior. In my quest to such an explanation as I wanted to now exactly this, people only repeated what was said in school or evade an answer by saying that it is to complicated to explain. And here you are (!) doing it in twelve and a half minutes! This basis shows also what I already thought for years and just recently showcased by the wonderful youtube channel Veritasium by Derek Muller. That, in electrical current, it's actually the electric-magnetic waves that carry the energy and not the flow of electrons, because electrons hardly flow anywhere! They just pass on the electric energy to their neighbor and the electro-magnetic field which they create through the excitation brings the energy over to the other side. That's why the material of the wire, their width, wheter it's a bigger solid core or separate strands and isolation can make a huge difference in how that current or signal is distorted or not. Also, as all matter interacts with each other through their electro-magnetic fields, no matter how significant. As such, we, as a big lump of matter, radiate the combined and averaged result of all the matter we exist off and unconsciously influence each other fields. Most people would say that the influence is so insignificant that we would even notice it, but it would explain a lot of phenomena in which people "sense" something that they can't explain like somebodies mode, intentions or why sometimes you feel attracted to somebody who, physically, at first appearance wouldn't attract your attention. Maybe a bit far off, but not in the basic sense of this fundamental physics fact. Long story short, Incredible how you managed to bring this subject so clear and yet in such a short amount of time!! Thank you so much! ☺🙏 1 Reply Broden Connolly Broden Connolly 1 month ago I’d love to see an in-depth video on quantum entanglement.

I really like the Clifford algebra story of electromagnetism, where the E field is space-time bivectors and the M field is space-space bivectors, and you can easily derive how relativistic boosts will convert one person's electricity into another person's magnetism and vice versa. IMO the magnetic field should be drawn with little spinning disks instead of vectors for this reason (drawing the bivector, not the normal, which is a 3-dimensional coincidence.) 2 Reply xersxo xersxo 2 weeks ago This is the greatest explainer video on electromagnetism I have ever seen.

Reply Cy "kkm" K'Nelson Cy "kkm" K'Nelson 1 month ago (edited) Actually, human eyes is sensitive to linear polarisation, albeit very little. IPS monitors work by rotating polarization direction, which changes pixel brightness against a fixed plane polarization filter. When screen is fully white, the polarization of electrically controlled variable angle in-plane per-pixel polariser and the fixed filter coincide, so the pixel brightness is maximal. You can see it if you look at an IPS screen in polarised sunglasses and rotate your head—the screen will become fully dark in a specific orientation (horizontal, vertical, or 45⁰, depending on a particular panel). When looking at the fully white IPS panel, some people see a hard to describe effect (I do see it, and I believe everyone can, it's just hard to notice): I see a very slight vertical bluishness and horizontal yellowishness (may be vice versa, or diagonal; depends on a panel). It's not lines or something, it's kinda direction-related tint. I can't find better words, “bluishness in one direction and yellowishness in a perpendicular direction“ sounds weird, but once you see it, you'll notice. It's like a tinted cross at the focus of your vision, with each line going wider in the away from your focus point direction; it's kinda shimmering, more prominent when your sight wanders a bit. Look at the very center, but do not fix eyes on the point, let your sight wander around the center of a fully white page, within 1cm or so, and you should notice it. This will not work on AMOLED panels, common in new phones, tablets and notebooks. Confirm that your display emits polarised light—white screen should turn fully black when you wear polarised sunglasses and rotate your head (or screen) in some orientation. In other word, the white light from the screen must be 100% linearly polarised. All today desktop monitors 19" and above likely qualify: AMOLEDs are economical only up to 17" so far. Here's another eye optics trick (unrelated to polarisation, but since we're talking about human vision...). Fix your sight very steady on a dot on a bright white screen, or even a well-lit sheet of quality white paper (you need a bright white light, day sunlight works), as steady as you can. In about 20-30 second, you'll see very pronounced network of irregular dark lines crisscrossing the whole white field. These are blood vessels in your retina. Nature decided to inverted mammalian retina (we're made, like, “it kinda works, don't fix it”): the light-sensitive cells are on the back side of the eye, and the nerve fibers and blood vessels are in front of it, in the path of light. This is also why we have the blind spot, where all nerve fibers connect into the optic nerve and go to the back side of the eye through a hole in the retina... Octopus' eye has convergently evolved to be very similar to the mammalian eye, with very similar lens and iris and annular muscles controlling focus and iris size, but their retina is installed the right way forward. :) Double whammy, since we live in air, a very transparent medium, and octopodes in the ocean, where water is full of suspended organic, both excretions and decaying remains of sea life, so the animals hardly benefit from their eye upgrade we did not get. :) 1 Reply Old Man Black Socks Old Man Black Socks 1 month ago Your analogies and animations provide a deeper meaning.

That said, it is probably the best video I have seen on the topic in general, but with some caveats- in the form of questions generated or things not being clear, or things being done a bit too quickly. I can give specific feedback at certain points in the video, if you'd like.

Reply 1 reply SmogandBlack SmogandBlack 1 month ago Very nice, thanks 😊. When we represent the path of an electromagnetic wave, we actually display the direction taken by the energy carried by that particular wave, if I'm not wrong... if we represent its profile we can see both energy direction and the oscillation of the electric field. And if the wave crosses the screen from left to right, we can imagine the magnetic field pulsating towards us... am I right? I often wondered why the two fields are orthogonal and what does this mean... does it mean that both fields are bi-dimensional and there is no excitation in the 'space' between them? On either side? No excitation inside that peculiar 90° space nor in the remaining 270° (which we can call the 'quiet' side)? Isn't it weird (and very interesting)?

Why does it actually bend during refraction? I slows down because the field interact with the atoms inside it, but why bend? I mean what is the mathematical equation behind it.

It's pure speculation on my part but those videos for sure keep my brain running - such an underrated channel. 1 Reply Sundoren Aesir Sundoren Aesir 1 month ago (edited) can you please explain why light path bended in refraction. I understand the slowing down but bending should happen at the surface and should have a different mechanism than interference inside water. There should be a heterogenous distribution of the EM energy just inside the 2D surface creating strong interference in the inside (water) but lower in the surface (mean density of both air and water) this partial interference should create the bending of light due to partial slowing down of the inside part of the energy but not the surface part of the energy. Since light trajectory is perpendicular to the E field (magnetic component is created by E field), partial cancelling interference-based slowing down in the inside but not the surface causes partial strength distribution of the electrical field which results a new E field more proximal to the surface making the light trajectory which is perpendicular to the E field towards center. With more energy/unit= wavelength the more bending will occur due to the strength of partial distribution/unit explaining more bending at higher wavelengths and vise versa. Is this correct ?

Reply Muhammad Rafiq Muhammad Rafiq 2 weeks ago Incredible Reply eXViLs - 8B008B eXViLs - 8B008B 1 month ago (edited) just to add to video.. particles we talk about are waves, and waves are particles, as they deliver energy in distinct packets.. Frequency of wave changes delivered energy, where shorter waves are more energetic (they transfer more energy to particle they hit), while for lower frequencies you need more mass to absorb energy, so they can easily pass trough matter. Adding energy to atoms makes them more energetic (their kinetic speed increases) and thats what we feel as heat when they form molecules.. they jiggle around more vividly and absorbing that jiggle is what heat transfer is.. also PV=nRT .. adding energy to particle not only increases heat in closed system, but also pressure (as there is more and stronger bounces on walls of closed system).. increasing volume lowers temp, as atom itself doesn't have any temperature. Water absorbs microwave energy really well, that is why that frequency of waves heat us most, and higher energy waves just kick out electrons from atoms.. Atoms w/o electron is more reactive, can lose bond with other atom by that kicked electron, that's why radioactive energy harm us, same goes for free electrons from food or other things. When it comes to interference topic, different energy waves travel at different speeds and not only light, that's how prism effect works. Also atmosphere has a (strong) color, it absorbs green and blue, so it is orange (yeah rly).. that's why you see red moon or red sunset/sunrise, and why sun is orange from our POV! (while indeed the sun is just white - thats how you would see it when you would be in space (tho surface temperature dictate color, and 6000K of sun would be nice white light) - you can see sun color on full moon, as it only reflect light without thermal radiation (as moon surface is cold) Also I would like to know how reflection works on non conductive materials from this video.. only way is smooth surface... as far as i know light (and other) wave bounces from surface, and smoother surface make wave less scattered, so less energy is lost and "cleaner" the image looks.. also different waves travel different length in material, thats why mirrors are green-ish and not silver-ish. 1 Reply Science Learning Science Learning 1 day ago Amazing explanation way Reply timetravelling Blockhead timetravelling Blockhead 4 weeks ago If only I was this good at teaching. 1 Reply Unknown Entity Unknown Entity 1 month ago Also if blue scatters the most why is the air near the ground not blue? missed to mention rayleigh scattering and particle size.

When a charged particle is moving at a constant velocity, it creates both an electric field and a magnetic field. The strength of the electromagnetic field created by a moving charged particle depends on the amount of charge and the velocity of the particle. When a charged particle is moving in a straight line, it will not emit electromagnetic waves. This is because the particle's motion is not changing in a way that would cause it to radiate energy. In order for a charged particle to emit electromagnetic waves, it must be accelerating, which means its velocity must be changing. So to summarize, a moving charged particle at a constant velocity will create an electromagnetic field, but it will not cause an electromagnetic wave to be emitted. So there is no disturbance in the first place like the video suggests. 1 Reply π π 1 month ago (edited) The extreme points of Gravity and Quantum field is singularity...this seems ,The two oppositely behaving theories are existing at the same time and at the same place in singularity.

The more density of particles there is in a specific zone, the quicker it will expand, like with water, where sound propagates faster because of this reason, being far more dense than air. Photons are known to have a double nature, being both a wave and a quntum particale. This is also the reason why photons still have an impact on particles with mass despite having none themselves. It's because they're also waves and, through their pression on other particles, allow them to still impact physically other particles but not be impacted themselves since physical interaction happens because of the exchanged mass between the objects. 1 Reply Shadow Fax Shadow Fax 1 month ago $5.00 Thanks! 1 Reply Timothy Timothy 2 weeks ago All frequencies vibrating in space are avoidance patterns of both repellant and propellant.

Equalized temperature is not same as zero temperature.

The part about mirror/metal reflection seemed to me to Imply that the light striking the free electrons at the surface which started them oscillating sympathetically and that started an emanation both into and out of the metal. The inward waves phase cancel and outward result in reflection. I think this ignores the elastic nature of this special interaction; some mirrors are nearly 100% reflective. Waves that are phase cancelled still propagate yet nearly one hundred percent emanate? I think the surface field of the mirrors offers a cloud of electrons and a very deformable springy subsurface that moves/distorts and then restores its field shape elasticity throwing off the photon at an angle that ‘mirrors’ its incident. I think propagation of electromagnetic energy is fascinating and elasticity is the vector to watch.

Clockwise and counterclockwise. Alpha and Omega. Perpetual motion. Thermal energy singularity frequencies propelled by resistance unidirectional flow, and repelled at the same time. Distance is reduced by redirected thermal energy trajectories backward onto itself as magnetic fields circling around space within mass. Making resistance in mass a repelling outward force of pressure known as weight contained in mass. Mass NEUTRALIZES resistance within as outward force of pressure known as weight. Equalization of frequencies interlocking, creating mass as outward force of pressure. Kinetic energy contained within opposite forces holding mass together. Only thermal energy can accommodate in various degrees of force. The degrees of temperature variations determines the flow of release. Only mass can disrupt mass cycling patterns. Resistance is equal to the mass. Mass will always repel towards the weakest point of resistance. Occupational space is the weakest point of resistance. The greater the mass, the weaker the resistance. Resistance is neutralized in mass as outward force of pressure known as weight. If the resistance is weakened by proximity massive mass. Then, the internal resistance repels thermal energy singularity frequencies outward towards the weakest point of resistance, which is the greater proximity mass. Stars lose their cycling patterns and reduce their outermost layers towards the weakest point of resistance. Occupational space of weakest resistance. Equalization of vibrating frequencies spiraling throughput space. Space is vibrating as dark energy out of entanglement. Entanglement is the equivalent to thermal energy and resistance in equalization losing distance of forward momentum to cycling circulation patterns holding mass together. Hydrogen absorbs thermal energy and expands into helium. Helium occupies more area than hydrogen. More outward force of pressure known as weight contained within mass. Kinetic energy contained within as vibrating force of outward pressure known as weight. Weight is the cycling energy within the mass. We vibrate to the weakest point of resistance. We transition through space as space itself amplified by resistance and thermodynamics. Both coexist throughout space as space. Mass amplifies space. Distance is redirected into cycling patterns. Light is cycling on a quantum field of resistance and thermodynamics. We can see, feel, and redirect light. Light is in equalization of resistance. Space itself is dark energy in resistance. Thermal energy singularity frequencies rebounding throughout space outside of entanglement is maximum momentum velocity in resistance. Light is vibrating through space as space amplified by resistance. Distance is reduced by entanglement. Redirected trajectories cycling thermal energy singularity frequencies in harmonics of flow. Unidirectional flow is both clockwise and counterclockwise. Disruption is from proximity mass trajectories. Andromeda is heading towards the milkyway galaxy. If the big bang happened, then galaxies would be moving away from each other. But if two universes join together, then you have Disruption patterns of flow. You will have collisions. The greater masses will be trajectories for weaker masses to lose their thermal energy singularity frequencies to. The pressure pushing outward force is no longer in equalization to resistance outside of entanglement. It breaks the cycling patterns holding mass together. Theoretically. The math is in equalization to resistance within mass, resistance equalization outside of mass, and the distance of forward maximum momentum velocity in resistance of mass. Mass vibrating space proximity is the weakest point of resistance. The more massive mass, is the weakest point of occupational space. Weakening the outside resistance causes the thermal energy singularity frequencies within to release their cycling patterns of renewable energy, and propels it to the weakest point of resistance.

I see a big mismatch in both theories. 1 Reply 1 reply ancientwisdom2012 ancientwisdom2012 3 weeks ago This video's intro is incorrect (for the first 1.5 minutes). The electromagnetic wave is not the same as (nor is it derived directly from) the static electric field nor the static magnetic field. The static electric field doesn't leave the vicinity of the charge once the particle moves. A new phenomena of EM wave (light) is emitted from that charge due to its acceleration. This light or electromagnetic wave is NOT simply a combination of the original two static fields. An Electromagnetic wave is often confused with the static Efield and Mag Field. (partly the problem lies in how the EM wave is expressed mathematically. It is always expressed as the hypothetical component vectors of the original true EM wave. These components are not really two distinct phenomena interacting, but are a unitary wave (with E and H vector components) that is too difficult to express in its true superposition form, mathematically.) The electromagnetic wave always moves away from the source particle, yet the static E filed ALWAYS stays near the charged particle. you imply and illustrate the e-field leaving the charge and changing into a EM wave of light. The magnetic field, which is a result of the charge's steady motion (non accelerating velocity), is also NOT going to convert into 'light' and simply move away from the charged particle. The magnetic field STAYS near the charges (and follows the 'right hand rule' for how the fields act around that charge). Otherwise, in practice as soon as electricity flowing on a straight wire either changed direction due to being an AC current or perhaps the wire bent in another direction (constituting acceleration in physics terms), then the resulting EM wave would -- if we follow your interpretation -- result in the e Field and Mag field no longer being detected at the wire where the current was flowing. However, that E field and Mag field can always be measured in any moving current. They dont dissipate or convert into EM waves due to motion. Em waves have magnetic properties and E field properties but are NOT equivalent to mere combinations of disturbed static Efields and static magnetic fields interacting. SO in short your video intro is not what happens in reality. You can still measure the e field at the charge and it requires a different type of equipment to measure this e-field(whether AC or DC) than is needed to measure the electromagnetic wave(which requires either a RF power meter or RF Spectrum analyzer). The magnetic field is only generated from constant motion of the charge, not acceleration(and would be measurable with a Gauss meter). Acceleration of the charge is what generates the EM wave phenomena. Any light / EM wave generated is not coming from the static fields already present but is energy generated as a reaction to acceleration of the particle.

Reply Unknown Entity Unknown Entity 1 month ago (edited) What did cause the vibration of atoms in the first place. They cause radiation because of Temperature (vibration). But what caused it in the first place? If it was radiation that caused the vibration of atoms then what caused the radiation? gpt3 answer: Yes, atoms naturally vibrate due to the movement of their constituent particles, even if they are in isolation. This vibration is a result of the uncertainty principle in quantum mechanics, which states that it is impossible to know the exact position and momentum of a particle at the same time. As a result, the particles within an atom are constantly in motion and vibrating, even if the atom is in isolation and not interacting with any other atoms or external forces. The vibration of atoms is known as the zero-point energy of the atom, and it is a result of the uncertainty principle and the fundamental nature of matter. The zero-point energy is always present, and it cannot be eliminated or reduced to zero, even at absolute zero temperature. In summary, atoms naturally vibrate due to the inherent uncertainty of the behavior of their constituent particles, and this vibration is a fundamental aspect of the nature of matter.

Reply Anton Adelson Anton Adelson 1 month ago MIND. BLOWN! 1 Reply Van sf Van sf 2 weeks ago (edited) You have also fundamentally misunderstood electric field because an electromotive force to drive a subatomic particle can be established only when there is a separation of two opposite charges, which are a negative charge and a positive charge, in which the electric field vectors point from the positive charge to the negative charge producing an electromotive force emf, in order to have a cross- field. Here you have only one single charge, which can be either positive or negative, which means that you have only one half of the electromotive force emf, and a positively charged particle can be only either a proton or nucleus without any electron or an cation. When a current i runs in a solenoid, it creates a magnetic field around the solenoid. But any electric current is always composed of 2 different flows of charges. One is the flow of electrons carrying negative charge from the negative terminal of the power source though an external circuit to the positive terminal, while the flow of the positive charge is actually transmitted from from the positive terminal , and atom to atom through the external circuit to the negative terminal. So, the current i here is the positive charge transmitted from the positive terminal to the negative terminal through the external circuit. But, without the flow of electrons in the opposite direction from the negative terminal to the negative terminal, there would be no magnetic field around the solenoid at all.. It means that a single moving positive charges or many single positive charge alone would never ever be able to form any magnetic field around such a positively charge particle as the way how you have assumed here. A single moving negatively charged particle alone , which can be an electron or anion, can never create any magnetic field around it either. There must be 2 opposite flows of 2 opposite charges in 2 opposite directions to establish a magnetic field around the 2 flows of 2 opposite charge. Yet, Mr Maxwell somehow still claimed that it was possible to have such a cross-field between a single positive moving charge and itself, and the charge itself creates a magnetic field as if an applicable electric field could be established by only one single positive charge, and the electric field could propel the positive charge itself. You guys should have wondered yourselves whether a positive charge or a negative charge could move by itself without any interaction with any other charge Can a capacitor have only one positive plate, and you still have the current i ? The answer is obviously no, never ever. Can an inductor have only positive charge running through it, and you still have the current i? No, absolutely not, because positive charge alone is merely of the total transmitted charge of cations or positively charged ions which can never run anywhere being fixed in their positions in the atomic lattice structure, while only free electrons carrying negatives charges can run around the inductor. The inductor must have both the positive charge transmitted through it, and negative charge carried by electrons running through it, in or der for it to have an magnetic field, which will cause an electric field in the inductor to drive electrons out of it So, what can make a positively charged particle move? The answer is that either another positive charge or negative charge, which either repels or attracts it Reply 1 reply nuance ascend nuance ascend 1 month ago there is nothing but Light , which is God itself .

The videos are not exciting to watch unless you think getting 3-10 times the amount of energy output, than he uses to create the AC electric field, is cool. I believe you do think it is cool. I know I do. No Billions spent, No Co2, Just American curiosity and perseverance. Fusion is a neat idea, but what could go wrong? I like the Kentuckian's idea much much better. As percentages go, the Kentuckian is making 20x more energy than fusion. ZC Techtricity is what he is calling it. Don’t forget to subscribe. Reply pyropulse pyropulse 1 month ago Why can't an antenna be 'driven' at the frequency ranges of visible light? That is, shouldn't we be able to drive an antenna to make it emit at a specific frequency that lies within the visible spectrum, such as driving the antenna at 545 THz (terahertz), thereby producing a wavelength of 550 nm (nanometers) corresponding to green light. To prevent thermal heating and emissions via thermal emissions, the antenna shall be sufficiently cooled such that 'superconductivity' an occur, thus reducing the resistance to 0 (zero) and providing no heat losses, and thus no blackbody radiation An antenna should be able to 'glow' at whatever 'pure;' color we want, by precisely adjusting the frequency corresponding to the desired color Reply 2 replies C C 2 weeks ago I wouldn't say the particle is "accelerating". It's vibrating.... Cuz heat Reply ailblentyn ailblentyn 1 month ago This is wrong in so many ways. For a start, simply accelerating an electron does NOT create EM radiation. If this were so, then, by Einstein’s Equivalence Principle, an electron sitting on a table top would also radiate. You need something like an oscillation to create EM waves. Reply ScienceClic English · 3 replies seraphic seraphic 1 month ago wait a minute, SPECIAL RELATIVITY is why you get a magnetic field from a moving charge!? Reply Luke EarthCrawler Luke EarthCrawler 1 month ago This is way too simplified to the point of being dead wrong. The part about polarization is particularly wrong. Atoms do NOT emit linearly polarized light. They emit one photon at a time, with angular momentum of plus OR minus one, ie. left or right circular polarized light ONLY because the photon is a fundamental boson with spin 1. What you see at the macroscopic level as linearly polarized light is actually an equal number of left and right circularly polarized photons. The true origin of electromagnetic waves can only be explained with quantum electrodynamics (QED). Maxwell's equations are an approximation as it considers the EM field a vector field that is continuous (i.e. not quantized). There are no photon is Maxwell's equation. Undergraduate quantum mechanics is also an approximation. When it deals with light-matter interactions, the atoms are quantized but the EM is not. You can do a lot within this approximation, but not everything. To truly explore "the origin of electromagnetic waves", you need to quantize the atom AND the fields... i.e. you need QED. 1 Reply 1 reply Jon Little Jon Little 1 month ago This is not an example of good science nor good science education. For example, despite the comments made about the different "types" of electromagnetic spectrum, there is no intrinsic difference between these types. The "types" are arbitrary differentiations of frequency based on human experience; there is nothing in physics that defines a qualitative difference between "infrared" waves and "visible" waves. The difference between the frequency of an "infrared" wave and a "visible" wave, and between two "visible" waves, is the same thing. Reply 1 reply Francesco Francesco 1 month ago where can I find the explanatory music? Found nothing on SonarEffects channel Reply David Lloyd-Jones David Lloyd-Jones 1 month ago (edited) It is inaccurate at 3:02 to say, "It is necessary to look at the microscopic scale" and then to start nattering on about atoms. Individual atoms and distinctions between and within them are at a scale far smaller than anything distinguishable by visible-light microscopes. So you're not dealing in science here. Your video is a lot of skool-teecher hand-waving. 'Fess up! All the stuff about rubber bands going in three directions, around 5:00, is just a lot of total nonsense: the number of directions from a nucleus to any point in the electron cloud is infinite, (or just very very large if "space" is granular or quantized). It most certainly is not three. I suspect you're suffering from the superstition that since your room has walls meeting at ninety degrees therefor space-time comes in flat and square chunks. Again, that's not science. That's the grade-school classroom's wall closing in around you. And these "partikoos" you talk about? Are we to assume that by partickoo you mean "particle"? Take it down and start over. This shoddy video is doing no good for anybody.

I absolutely love your lectures. I cannot dare imagine the hardwork that goes into preparing them.! I mean, if I wasn't told to check out your lectures by a friend, I would have missed this great work! I'm currently in the XII grade, and Electrostatics is like the first unit of our physics book which comes in totally scary two big volumes. And such scary books really don't serve the motivational purpose. I'm more like depressed reading it. And when you don't have a Physics teacher at your school, you have no option but to rely on your capability of comprehending things as printed and published down in the book. So eventually when topics like AC and Waves started bouncing of my head when I didn't even have the basics of electrostatics cleared, I got demotivated enough. I had started hating the subject and the beauty behind physics faded somewhere there. But, ever since I've started watching your lectures, my love for physics has rekindled. I cannot thank you enough for that. And right now, I am so gravely jealous of these students who got to sit in your lectures and watch you live at MIT. I'm a big fan! Damn! I so much wish that I could see you in person and then I would have learnt to draw them sleek dotted lines.! :) 161 Reply Lectures by Walter Lewin.

Why is the speed of light what it is? Maxwell equations visualized Arvin Ash 755K subscribers Join Subscribe 57K Share 1,751,132 views Premiered Mar 25, 2020 #electromagnetism #speedoflight #maxwellsequations Twitter: @arvin_ash The History Guy video on Maxwell: https://youtu.be/NuWEqE4k230 . Why is the maximum speed of the universe the speed of light? Maxwell’s equations explained and visualized. Why is light so fast? What is light made of? Almost all modern technology is based on Maxwell’s equations. Not only do they describe every electrical and magnetic phenomenon, but hidden within these equations is a fundamental truth about the nature of light, and why it is the ultimate speed of the universe. We are going to visualize the equations with graphics. Objects have something called a charge. This is a property of matter like mass is a property of matter. If you have a static object with a charge, it will affect only other charges. And if you have a static magnet, it will affect only other magnets. But if you have a moving charge, it will affect a magnet. And if you have a moving magnet, it will affect a charge. That's what the four equations are telling us. A charge is the source of an electric field. If I have another charge, you can understand exactly what force it will feel. The first equation is a formula that tells us how electrical charges create electrical fields. It is based on concepts developed by Carl Friedrich Gauss. Permittivity of free space is required in the equation. It is the resistance of free space against the formation of electric fields. The second equation is called Gauss’s law for magnetism. It says that if you had the same sphere but it was a magnet, you will never find a configuration where the magnetic lines of force always point outward, or always point inwards. In other words, a magnet will always have two poles. There are no magnetic monopoles. The third equation is called faraday’s law. This law says that if move a magnet, you will create an electric field. This equation tells engineers how to generate electricity from a generator. The fourth equation is Ampere’s law. It says that if you have moving charge through a wire, or an electrical current, you generate a magnetic field. This requires a constant of nature called mu naught. This is the permeability of free space. This is the ability of free space to allow magnetic lines of force to go through it. Note that there are two terms in this equation, one term tells you the moving electrical charges can create magnetic fields, and the second term tells you that moving electrical fields can also create magnetic fields. This idea of magnetic fields being created from electric fields was Maxwell’s addition to Ampere’s law. #maxwellsequations #speedoflight #electromagnetism Both of these constants have to be measured, since they are inherent properties of nature. They are not derived from anything. What does this have to do with light? If I take an electric charge and put it on a pole, and I just move it up and down, what will this cause? According to ampere’s law, if an electric field moves or changes with time, it would create a magnetic field perpendicular to that. And because of the changing movement, the magnetic field would also be changing with time. And according to Faraday’s law the moving magnetic field lines would create another new set of electric field lines. Now, since the same thing is happening to these new electric field lines, that is, they are changing over time, they would in turn create new magnetic field lines. And the new moving magnetic field lines would create yet more electric field lines. You have just created a self propagating wave. What is the speed of this wave? You find this using advanced multivariable calculus which Maxwell was very good at. He comes up with is 1/V^2 = epsilon naught * Mu naught. Solving you get Velocity = Sq root (1/epsilon naught * Mu naught). So what the equations are saying is the velocity of this wave is inversely proportional the permittivity and permeability of free space. It makes sense that the velocity of any wave would be inversely proportional to the resistance of the substance it is traveling in. You might ask, well why are mu naught and epsilon naught those exact values? No one knows why. These are just the constants of nature. Now we take the measured values of these two constants, and do some simple math. The speed of the wave is about 300,000 km per second. Maxwell realized that light must be an electromagnetic wave. About 40 years later another great scientist by the name of Einstein did his own thought experiments inspired by Maxwell’s equation. And his thought experiment was based on one simple assumption. He asked if the speed of light is an inherent property of space, why would this speed be any different based on the speed of the observer? And it was from this simple assumption, that he came up with the special theory of relativity in 1905 which changed our ideas about the nature of time.

Arvin Ash Pinned by Arvin Ash Arvin Ash 2 years ago (edited) For those of you wanting to know exactly how Maxwell derived velocity using multivariable calculus, here is a paper that shows the details of that derivation: http://srjcstaff.santarosa.edu/~lwillia2/42/WaveEquationDerivation.pdf . Also, this video may be helpful, https://www.youtube.com/watch?v=7hMPTdppBdA In addition, several people have expressed that the prism graphic is incorrect because the direction of the exiting light is pointing up rather than down. Take a closer look at the sequence of colors. This graphic is not exactly incorrect. It is simply an upside down prism. You may object to the light seeming to bend upwards, but this is just a matter of perspective. I took artistic liberty in that, I admit. Red would deviate more than violet. But yes, the rays would point downward.

I know recently the exact value has been measured to be slightly different (x1.000 000 000 55), but it all seems so close that it doesn't make sense for it to be just a random coincidence.. that maybe the 4PI is more meaningful than the exact number (and maybe the difference means a lot too). It's already inadvertently being used as a constant, only it's one we understand the meaning behind. In 3 dimensional space, if we imagine a field propagating from a source it is a sphere. The surface area of this sphere is defined as 4Pir^2. As radius isn't a constant and due to relativity a property defined by the observer, maybe this relationship is a hint to the true nature of causality and how space is defined. 4 Arvin Ash Reply Don Kloos Don Kloos 1 year ago Well done review with practical imagery and explanation.

The fact that all of E&M can be summarised in just 4 equations makes the subject the most concisely formulated in all of physics and science - I don't think there any other area that is so compactly expressed. Yes, one needs a lot of advanced calculus to understand and use the equations but that is true of many other areas, such as hydrodynamics and thermodynamics.

I developed extremely sensitive detectors for gas chromatographs. The last 5 years of my career I was designing a Liquid Quadrupole Ion Trap Mass Spectrometer. I never used Maxwell's equations through out my whole career. The equations that I did use were E=I*R, ohms law, P=I*E, watts law, Q=C*V, charge of a capacitor is the capacitance times the voltage on a capacitor, Q=I*T, charge of a capacitor is the current times the time of a capacitor and I*T=C*V. This leads to V= 1/C int(i dt), the voltage of on a capacitor is equal to 1/C times the integral of the current over time and I=C * dv/dt, the current out of a capacitor is equal to the change in voltage with respect to time. Yes, there are other common formulas like XC= 1/(2*pi*F*C) and XL=2*pi*F*L, to measure the capacitance and inductance reactance with frequency. We can't forget about T=RC, time constant of an capacitance-resistance circuit and T=L/R, time constant of an inductance-resistance circuit. Yes, I learned about Kirchhoff's law, Thevenin and Norton theorems too. 2 Reply 1 reply JR W JR W 5 months ago As all stand on the shoulders of their predecessor giants (eg Maxwell on the shoulders of Faraday), I seem to recall that c can also be described as the proportionality constant between the strength of the electric and magnetic fields.

But I have a question from my college days (1963-66) which nobody could answer satisfactorily. The question is based on Prof Rowland"s experiment. Here I present it: If I put a charged body (fixed) on an insulated turntable, and (also fixed) with a highly sensitive magnetic sensor/magnetometer and a video camera with a transmitter to instantaneously transmit the output of the sensor and then set the system on rotation. I think: 1) I shall register a magnetic field in the space surrounding the lump of charge on my handheld magnetometer as there will be a time-varying change of flux w.r.t. my device (as Prof.Rowland observed), in my frame of reference (standing on the ground), but 2) Will the output of the transmitter show the presence of a magnetic field around that charged body on the rotating turntable as there is no time-varying change of flux between them, (they are motionless w.r.t. each other)? I hope NOT! If so, then, how can the concerned volume of space experience simultaneously “a presence and NO presence” of any magnetic activity? What exactly will be happening in that volume of space around the charged lump and how can it be possible/explained? If magnetism is a physical phenomenon, how can it be so different to different observers, in real-time and space? Hope to get a kind reply. Thank you. With my best regards, I remain.

As a student of electrical engineering I remember the required exercise of sitting and deriving Maxwell's equations from the basic laws and for the first time I really felt that I was on the doorstep of truly understanding something absolutely fundamental about the universe.

I even wonder why i didn't subscribe the first time, it's done now :) One historical point I'd like to add, though it was not the point here: originally, Maxwell did not write the system of 4 equations attributed to him, actually he has never seen this beautiful system. He initially came up with much more complex system of 20 equations involving quaternions. This system was later shown to be simplifiable and writable this way but Maxwell had died by then. Needless to say that he was the original brilliant mind behind this theory and he did the hard part of the work, but that's how it happened. He must have been pretty damn good at math to sort out the speed of the wave from a 20 equations system with quaternions!

But as far the definition of permeability it is the ability of a material to get magnetized and hence the material with higher permeability is able to orient more magnetic dipoles in align with external field and they will create more magnetic field. Reply NEKNIM NEKNIM 1 year ago So if the speed of light is defined by the permittivity and permeability of electric and magnetic field constants, it seems that if those constants were to change the speed of light would change too (as you mentioned). Are there any theories that question the uniformity of these constants throughout our universe? What about other forms of energy that not restricted by these constants? Could this theorize dark energy or quantum entanglement?

I feel nearer to understanding light that I was 20 minutes ago. But one thing still puzzles me. In a water wave energy is translated from potential to kinetic. When one is zero the other is at a maximum, so the wave keeps propagating. With light both electric and magnetic vectors are zero at the same point. How does the wave get past this point? What am I missing? In an LC oscillating circuit, as in a radio transmitter, voltage is maximum when current is minimum, and vice-versa, like the water wave; but why in the propagated wave are electric and magnetic vectors in phase?

Reply Kevin Auguste Kevin Auguste 1 year ago Dude. Thank God for people like him. 1 Reply BUTCH NEWS BUTCH NEWS 2 years ago Nice lecture. My thoughts... Because ALL of our perceived reality is controlled by how quickly our brain can process reality, we have to do it one electron at a time. i.e. All nerve signals are electronic and can move only as fast as each electron will allow. So... the diameter of the electron becomes a big deal because no wave of any kind will occur until the electron moves. So, you have to displace space with enough energy to move an electron for a brain to recognize anything, at all. The voltage will determine how fast an electron moves vs the resistance... how to push an electron through its own volume, in space. The point is, there is no wave until an electron moves. One ampere per second will be the number of electrons in a string about 300,000 kilometres long. The resistance of an electron to motion, in space, will be the same as the resistance of space, itself. Things that are equal to the same thing are equal to each other.

The only missing point is, why do electric and magnetic constants define not only the speed of light, but also the speed of gravitational waves, or the limiting speed of any moving object? The answer might be that it's not exactly electricity and magnetism defining the speed of light - but rather the speed of light plus the laws of electricity defining magnetism. Lorentz transform (the core of special relativity) applied to Coulomb law (the relationship between electric charge, permittivity and electric force) gives the magnetic force. 1 Reply 1 reply Classix Classix 2 years ago Imagine how sick it must've been to realize that light itself is this electromagnetic wave thing that you just came up with.

If we look at the Einstein's special relativity theory, the speed of light in vacuum has constant velocity of 186,282 miles per second. If you could travel at this speed, you could go around the Earth 7.5 times in one second. In 1994, Miguel Alcubierre proposed a method that would take us beyond the speed of light limit. In his mathematical theory, he used two points in space-time to demonstrate the expansion and contraction of space fabric. The idea of Alcubierre's theory was that we could use this space-time warp to make an object travel faster than light. Neil deGrasse Tyson takes examples from science fiction works like Star Trek to demonstrate and explain how an advanced civilization could be capable of manipulating the fabric of space-time itself in order to travel faster than the speed of light. Einstein's theory of special relativity states that energy and mass are interchangeable, and speed of light travel is impossible for material objects that, unlike photons, have a non-zero rest mass. Neil deGrasse Tyson explains how Einstein's theory of general relativity allows for time itself to slow down if you travel at relativistic velocity Einstein's theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. Even if a wormhole could form, it would most likely be very unstable. Wormholes are still speculative because nobody really knows if you could pass through it. The math suggests that you need some sort of exotic material to pry the throat of the wormhole opening so that it wont collapse in on it self. Even then it is possibly unstable. #neiltyson #science #lightspeed SUBSCRIBE to our channel "Science Time": https://www.youtube.com/sciencetime24 SUPPORT us on Patreon: https://www.patreon.com/sciencetime BUY Science Time Merch: https://teespring.com/science-time-merch Sources: Jose Luis Blázquez-Salcedo, Christian Knoll, Eugen Radu.

Therefore, you can technically affect a particle at a desired location as long as you can observe the light from said location, ie the observable universe, I believe this is possible due to particle wavefunction probably and quantum tunneling. Reply dathyr1 dathyr1 5 months ago (edited) Thanks for the video. Very informative. So for right now, The possibility of people or matter going "Faster Than Light" speeds is as others say a dream and only in the Movies. Right now with our technology, we will be lucky to visit the nearest planets, let alone going to the Stars. I like the explanation of if a person would go the speed of light, Time would slow down for him, but everyone he knew back on Earth would grow to be very old or dead when he does came back to Earth. Kind of like the "Time Machine" Movie with Rod Taylor. Last thing, the stars/galaxies that we see in the night sky are actually from a distant past snapshot. So what we see now may not even be there or have changed so drastically and wont know it till hundreds of years from now on Earth. Nearest Star to us is 4 light years away.

Darn it, I just had it! :) Reply Gerald Scott Gerald Scott 1 year ago I have studied the concept of faster than light travel for several years. Relativity clearly makes it impossible to travel faster than the speed of light through normal time and space. And I have completely discarded the wormhole idea, talked about so much By the late Stephen Hawking. Even if wormholes exist, and even if they are stable, they would not take you where you wanted to go. You would have to find the entrance to one, enter it, and come out who knows where. And could you even get back? Faster than light travel is going to require the warping of spacetime by the spacecraft itself, and there will have to be a way to control speed and direction. Also, it would have to be on a very small scale, The distortion of spacetime would have to be an area not much bigger than the ship itself, to avoid damaging other things. Navigation would be an issue, because at several times the speed of light, which would be necessary to get anywhere within a reasonable time (and I mean getting to Alpha Centauri in no more than, say, 24 hours) you would have to be able to control what science fiction calls the "warp field" Your ship would not be moving, spacetime would be moving. It's like being in a car where the road is moving instead of the car. This will not likely happen in the next few hundred years, but if we are ever going to travel to the stars, it will have to happen at some point. It is the only way to get there. 14 Reply 12 replies Derek Halley Derek Halley 6 months ago Question… So if we are traveling to a destination that we see from earth, is there a possibility that it’s not even there because it has since traveled or ceased to exist altogether? 6 Reply 2 replies cNazKool _it cNazKool _it 1 year ago a former friend of mine is a phd in electrical engineering with another masters in math. he says the mathematical distances of just the visible universe is beyond human comprehension. its a shame we didn’t launch a dozen voyagers back in the seventies all going different directions. some day someone brave like me needs to volunteer for a deep space one way mission 🖖🏿 Reply 1 reply Jason Webb Jason Webb 1 year ago I remember when Neil had a group of people talking and Will Weaton came on the stage. Neil was talking about the Enterprise and how the warp drive worked. He took a piece of paper and folded and shoved a pencil through. He opened the paper back flat and says this is how the show Star Trek was able to get from point a to b during a commercial break. Then Will broke the bad news to Neil. The warp drive didnt work light that. In the original Star Trek the Warp drive was the speed of light. So warp 1 would be the speed of light times 1 and warp 2 would be twice the speed of ligh and so on. Now i can totally understand why Neil would think and say this. Cause stars are so far apart, it would take forever to get from one star to the next. Like for instance from Earth to Alfalfa Centauri, its around 4 light years away from Earth. So by going warp 4, it would literally take 4 years to get there. I like the folding of space better then the speed of light theory and it would be a better explanation for how they were able to go where no man has gone before. 3 Reply 1 reply Kevin Wallace Kevin Wallace 1 year ago I really enjoyed this topic, thank you.

So a vision of a whole galaxy at any given moment could only be brought to you by instantaneous communication. Which is how it was taught before World War Two. The speed of light to create a new beam of light was considered to take time to create, but once established a partial block to that beam was recorded instantly.

Let's say that we invent working nanotechnology and by manipulating entangled atoms which we purposely entangle ourselves, this could show if nanotechnology worked through entanglement. Now what if the particles before we entangled them, were already entangled with other particles from long ago, say as far back as the big bang for hypothetical. These entangled particles could be very distanced from each other. I'm talking on the opposite sides of the universe in theory. Now if one is affected and the other entangled one is affected immediately, wouldn't this be communication faster than the light it would take to travel between them, as in faster than light, actually instantanous connection. If so this has consequences. A sci-fi film called "Kill Switch" had an idea of entangled worlds mooching off the power of one to empower the other. Of course in the film this was destroying both worlds, and a guy is sent to the other world to activate a kill switch to destroy that entangled world and save his own. Now with this entanglement, even though they don't call it that, it creates the two worlds to be side by side and able to take the energy of another. However in the film this other world is artificially created by this handwavium physical process, so much that there are copies of the characters in the hero's world, and all the planetary features, buildings and businesses and political groups, just mirrored. Unfortunately this mirroring would make one of them actually antimatter, and thus a very dangerous situation where contact between either world could set off a chain reaction destroying both worlds. Now matter and anti-matter pairs can arise from a high enough energy in the electromagnetic field, and in reality with entangled particles if one say is spin up the other is spin down, so this entanglement of mirrored particles is potentially possible, it just wouldn't create it instantaneously next door. Now if we are entangled with other particles, then there indeed could be particles near us we could manipulate that would manipulate already entangled particles somewhere else. Let's say we create half a quantum computer and have the entangled particles create the other half, thus allowing a form of computerized communication between the two. Now if we can do this, we could create robotic bodies that can create nanotech and use nanotech to manipulate other particles around it. More on this later. But let's say we create a quantum AI that can observe from both halves of the quantum computer. We would be able to theoretically see some other part of the universe through such a device. In fact in science fiction there was a device based on faster than light communication called an Ansible by Ursula Le Guinn. But if we can build robots and AIs, why not entire colonization ships, or android bodies we could remotely control through a BCI. We could thus travel to another body somewhere else in the universe without having to travel all the way from our local area location to the location of the entangled versions. This could allow us to explore other parts of the universe, instantaneously, without having to even move beyond our solar system. We could be entangled with other humanoids on other entangled planets and such a computer could allow first contact. Now what if we take this a step further, we create nanotech entangled with other nanotech via an entangled quantum computer. Now we have that nanotech manipulate other atoms nearby and create another quantum computer robot that could be entangled to another in a totally other distant part of the universe. We could create, theoretically, a series of communicating quantum AIs across the universe, entangled and interacting via nanotech creating a sort of quantum entangled intergalactic internet. We could create sensors connected to this entangled quantum internet, thus detecting things like gravitational waves, gamma ray bursts or even explore how fast the universe is expanding, and thus be able to measure things like dark energy or dark matter, and create basically exploration vessels throughout these entangled quantum internets, which again could have colonists or explorers in humanoid robotic form, allowing us to transfer our consciousness or pick up the sensory information from any entangled robot in the universal system. In essence this could allow us to create ambassadors and emissaries to communicate with other alien life forms, and create basically a way for people to travel to other parts of the universe through a BCI travelling through what would be in essence quantum hyperlinks, like the hyperlinks between web pages in our current internet. We could travel through hyperspace essentially without having to travel through hyperspace, and because these quantum computers are entangled, they would maintain connection no matter how far they drifted apart. We could study and explore the entire universe, create VR constructs of those monitored zones and do so from the comfort of our own solar system or planet. If we can do this to BCIs we could also link thoughts into a hive mind of sorts, and by entangling our own neurons with nanotech or entangled particles, we could upload our consciousness onto quantum computers and essentially live forever in these simulations created by the quantum computers. We could also learn and map how the matter in our own solar system is entangled with the rest of the universe, and thus find out how the universe is quantum entangled with itself. Thus we have essentially a permanent instantaneous connection all around the universe, uploading our minds into systems that can be as tough as diamond and able to run off the energy of a star, connect our minds into a supermind, and be able to hop from body to body, star system to star system, planet to planet, galaxy to galaxy, and maybe, just maybe universe to universe. This is instant communication using only nanotech and quantum entanglement and AI, which is technology we could develop in the near future. This means no having to make anti-matter to power starships to get to the speed of light, or create exotic matter like dark matter or dark energy or negative energy to hold open huge wormholes. That stuff will happen in the future possibly, but this means that within a century or so, we should have technology able to do experiments to see if this hypothesis is right. If so, the places we could go instantaneously could be unimaginable. This is like me in Perth communicating with someone from Pennsylvania, 12 hours apart, on opposite sides of the planet, communicating instantaneously on the internet. This means that sensors could detect dangers long before they would affect our region of space, in real time without any potential time travel or temporal paradoxes. And if quantum teleportation is workable through this system, imagine being able to hyperjump to another part of the universe, like the space ships do in the recent Battlestar Galactica series. If we can use 3D printers using nanotech, we could fabricate anything connected to the entangled quantum computer system. This means also backups eternal backups to the objects we manufacture with nanotech. In fact a working nanofabrication machine could exist with certain technology like a 3D printer and a scanning tunnelling electron microscope. They were able to spell IBM in xenon atoms back in 1993. Imagine hooking that nano-manipulator tech to a 3D printer with superconductors in basically subzero temperatures in space, which creates the coldest environments, and we could build nanotech from the atom on up. We also have nanomachines that can take in certain inputs and create certain outputs, we just call them cells or viruses or bacteria. We could genetically engineer nanofabrication through bio-tech or wet nano, or use the 3D printer version or dry nano. ANd if entanglement proves to work in this, we could create the whole object by only manipulating half of it.

Salt n pepper heavy d up in the limousine 32 Reply 3 replies Tony Alvarado Tony Alvarado 8 days ago (edited) I'm stuck on the assumption of traveling near the speed of light accounting for a huge change in time (or time traveling due to speed) as stated by Neil. For example, if an explosion occurs with a young person that will see it who is also on a call with another young person on a spaceship departing at the speed of light just prior to the time of the explosion, regardless of your arrival at another point in space faster, the explosion has happened, and you're just waiting for the light to reach you. I can understand you don't see it yet, but it has happened already. In my little brain, one person is telling the other "dude, it exploded" to which the other says, "Yup, I heard it on the phone but I'm so far now that I have to wait to see it". I guess you could argue that cell service would be iffy since it's traveling at nearly the same speed as the cell signal being received on the spacecraft...lol. Likewise, you could also argue that if you are only at half the speed of light, given enough time, the light of the explosion will surpass you. Does that then mean you are now going backward in time? I'm obviously not an astrophysicist but wonder if others have similar problems with this stuff. Having written that, thoughts of being at several multiples of the speed of light (not acceleration to the speed of light) may have crazy implications. However, Neil (who is wicked smart) stated you would actually go into the future. So, in that call scenario that I gave, you would basically be talking to the grandson of the young dude who you talked to as you took off.

When you launch the device and it accelerates to the speed of light you turn the flashlight on, would the light emitted by the flashlight travel at twice the speed of light? I think that it would based upon Einstein's theory of relativity. My reasoning is that the flashlight shares the same inertial frame of reference as the craft that it is attached to. However, the light emitted from the flashlight will accelerate and leave the flashlight's inertial frame of reference at the speed of light thus achieving a velocity of 2 times the speed of light. So, in this case does 1 plus 1 equal 2 ? Lol Please let me know if you think that this is theoretically possible.

Is Time Travel Possible? - The Science of Time With Neil deGrasse Tyson Science Time 428K subscribers Subscribe 22K Share 978,036 views Jan 16, 2021 #TimeTravel #Science #NeilTyson Whether time travel is possible is among the most intriguing questions in all of science. Neil deGrasse Tyson explains how time travel into the future is possible through Einstein's general relativity theory. Time travel is a widely recognized concept in philosophy and science fiction. But is it truly possible in real life? What does physics tell us about time travel? Is it possible to travel to the past? There are some physical theories that can help us learn what time travel is and how it works. Neil deGrasse Tyson explains the nature of time and the conundrums of time travel. In Einstein's theory of special relativity time slows down or speeds up depending on how fast you move relative to something else. So, for an observer in an inertial frame of reference, a clock that is moving relative to them will be measured to tick slower than a clock that is at rest in their frame of reference. This case is sometimes called special relativistic time dilation. Time dilation may also be regarded in a limited sense as "time travel into the future. The faster the relative velocity, the greater the time dilation between one another, with the rate of time reaching zero as one approaches the speed of light. While some physicists argue whether time travel is possible, theoretical physicist Carlo Rovelli thinks that time is in fact illusion and our reality is just a complex network of events onto which we project sequences of past, present and future. Neil deGrasse Tyson is quite possibly the most famous astrophysicist if not the most famous scientist of our time. He is a science communicator and author and he explains in layman's terms whether time travel is actually possible. Neil deGrasse Tyson has written numerous scientific books, his latest is "Letters from an Astrophysicist". #TimeTravel #NeilTyson #Science SUBSCRIBE to our channel "Science Time": https://www.youtube.com/sciencetime24 SUPPORT us on Patreon: https://www.patreon.com/sciencetime BUY Science Time Merch: https://teespring.com/science-time-merch Sources: https://spaceplace.nasa.gov/time-trav... https://wiki.physics.udel.edu/AAP/Ein... https://vixra.org/pdf/1504.0122v1.pdf https://www.nasa.gov/feature/goddard/... https://www.youtube.com/watch?v=iLKTZ... https://www.youtube.com/watch?v=wp6cn... https://www.youtube.com/watch?v=hYkXN...

That's why time stops if you travel at the speed of light. Even if you survive the round trip back to kill your grandfather and came back, the timeline you killed your grandfather is moving into its future at the same speed that your timeline you came back to is, and the two will never intercept. Wait 50 years and go back to that time line, you'll see you don't exist there and you had created an alternate timeline. If we ever discover anti graviton, the best we could do is visit either the past or the alternate timelines we have created. 377 Reply 57 replies Dardan Gashi Dardan Gashi 1 year ago This video literally explains of what happened in Interstellar (2014) movie.

You couldn't possibly break causality then... could you? 4 Reply Excluseive Excluseive 2 years ago The difference in the time on the planes sounds more like General Relativity. Considering only the velocity, people on the ground would see time on the plane going slower but people on the plane would see time on the ground going slower. To compare the clocks at the start and end the plane had to accelerate (and deccelerate) so overall time slowed down on the plane due to General Relativity. 3 Reply C6 C6 1 year ago One reason i want time travel: I would love to go back to my childhood with the knowledge I have right now, and see all my old friends.

I can see that reaching “light speed” bends the space in front of you but I feel like it changes your surroundings so it almost in absence is sucking you to the location point, but you would be in the same instance of time no matter your location. Which just makes it a neat instantaneous motion - so I don’t think your timeline would leave the time line per say if you left earth at light speed. I feel like it is possible somehow reverse a person timeline but that’s super sci-fi and that’s probably done at more of a cellular level by reversing cells to a point you were at your prime or possibly youth. But it’s not impossible per say if there was a wormhole that took you into a loop of bent versions of the universe to some degree in its past.

With this stuff you can do crazy things. Warp drive, stabilize wormholes, allow something like a probe to fly through the middle of a black hole & back out again without being crushed. 4) Wormholes.

Reply Antwaun Kent Antwaun Kent 1 year ago I've said this before, the reason we can't go back in time is because things would have to be vacuumed in reverse and all items that's collected to make you would need to be collected as well as all things around that presents would have to be reversely collected too. When you do try to go back, Its like glue and will be pulled back to its resolve placement in current time, like a dream. Time is sticky, like gravity is magnetic like. To break its glue, you'd have to vacuum all possibilities and draw them in with you like a black hole that pulls light and matter to a singularity point. Then something would have to sort out the absolutions of all items and its placements. Very small matter that share a very similar make-up can just swap placement because it doesn't disrupt the continuem of time/space/logic and principals. Think of the cat in the box. The unknown can't flex its muscle so its free to bend/ relocate in the folds subbing its place with a simple replacement to keep the fabric whole. Its like being in water with a cup and moving that water to a different location in the same body of water with-in the waters same body.. Displacement isn't changed but the water has been moved. So what really changed but your logical knowing you did do it? So what changed in the water was the water but the place taken was by a similar form, so no gaps leaving an no obvious change. Like moving a fish from one tank to another. If the chemistry is perfect the fish only knows its not at the original point. Minus displacement and knowledge etc. To move you; again., all that food/air/water/etc that came to make you would have to be collected and brought in the present at the same time you left to filling your void as you go to the past. But once you're there all that, that made you currently would be missing in your now present. A leaf piece here, a dinosaur eye there, and collection of water and air/ light displacement/ energy, etc would all be gone as you showed up. And in your old present, those same random items of that collective past would be here in some type of you to be. Like a random dinosaurs ey etc or like your shadow but in many associated forms. And the backlash could cause many butterfly effects to be determined however. Can't go anywhere without leaving something behind and no man needs nothing. You could create a mirror image, like a video game but you've multiplied your factors and or doubled your existence. Which is not the same but a simulated past in the a present. Should make perfect sense. You blur out the faster you go forward leaving a trail. Just reverse that idea and that's back time traveling. Reply G.A. Wilson G.A.

So, at the point in the future where we do as humans engineer some form of time travel tech, thats where the clock starts for the window in which we can travel in time.. this piece of tech records all events starting from the point that it was created at. Now we wont be able to travel to the future, but we will be able to travel to the past but only so far to the past as the limit would be the time at which this piece of tech was created.

I´d want to argue quite the opposit for clarity. "Now" is a very fluent thing and very much depending on "here" (as I´ll go into a little later, with a simple thought experiment). But also, "now" is relational if it is this moment (or the speed at which we are..) turning past into present. If one thing is traveling faster in time then it is only traveling faster in relation to another thing that can be said to be traveling slower in time and therefore going backwards in time in relation to the other thing. Both are always "time traveling". And this is a very normal state of affairs. From Einsteins general relativity you could argue that this kind of time-digression is the natural state of things for layers in any gravity well (or warped space) worth the name, like different heights on earth. There is quite a few zeptoseconds time digression between your head and toes within your lifetime and we live on quite happily and unencumbered.. It would seem that the "time is an illusion" guy has a VERY, very good point. But in that case.. all bets are of, right? Maybe something like movie timetravel with a push of the button or some sort of stargate will some day be possible? Well, do the math... Because time and space are "one thing" in a very practically important way, that people seem to forget about. Even if instant timetravel were possible, you´d have to take into consideration your "here".. Your position that is rotating around the earth at 0.4km per second, orbiting the sun at 30 km per second, 230km a second for our sun moving around the milkyway probably some other orbits in star-clusters and an estimated 73.3 kilometers per second for the general expansion of the galaxy (also you´d have to come up with a factor for how much the universe has expanded all those travelled distances in that second without falling into Zeno´s "illusion of motion" paradox in a kind of compound interest calculation at planck-times). This means traveling one second back would also mean traveling at the very least 340 km in an instant and probably WAY, WAY more.. But 340 km is enough.. There is a very good chance you´d end up 340 km underground or 340 km into outer space (which starts well and good at around 100km up, so you´d better bring a pickaxe AND a space suit) and only a very marginal chance you´d end up somewhere on the surface of earth low enough to survive the fall, but high enough not to be half-stuck in solid rock. The jaggedy circle of different heights on the surface of the earth intersecting the skin of the sphere of all possible positions within a 340km radius from your current position, where you could theoretically survive, means very little even if you would by some miracle manage to reach it. It really would be anybody´s guess at what speed you´d arrive, since you´d literally have to divide by zero to calculate it. Even if you were generous and divide by the plank time you´d arrive at more than 10 to the 50th times the speed of light after traveling only one second back.. From this simple thought experiment It seems math, logic and common sense aren´t on the side of potential timetravelers..

Less dimensions is less stable which makes it controllable with things like mass which is higher dimension Reply Paul Calhoun Waser Paul Calhoun Waser 1 year ago Physicists have observed tachyons, so they are no longer “hypothetical.” Most physicists do not know it, but all neutrino speed measurements have yielded average speeds slightly faster than the speed of light. And the neutrinos’ rest mass-squared has been measured from neutrino oscillations, and they are negative. The square-root rest masses are thus imaginary. According to special relativity, positive relativistic mass must always travel slower than the speed of light. Conversely, negative relativistic mass must always travel faster than the speed of light. Thus, neutrinos have negative relativistic mass and negative-imaginary rest mass. Neutrinos are tachyons and cannot rest but must travel faster than the speed of light in a vacuum. Although we would measure neutrinos as going backward in time, they do not actually go there. We measure what occurred in the past. The arrow of time goes uniformly forward in the rest frame. Everything we see and measure is in the past, but nothing goes there. There is no “tachyonic antitelephone.” I have uploaded several papers on these properties to Academia.com. 1 Reply Gutenburg100 Gutenburg100 1 year ago So basically time travel to the past is possible but requires a massive amount of energy.

I'm sure that someone has a hypothesis on how it can happen, but I've heard nothing of a way to test that, let alone a positive result coming from any experiment that would confirm it. 1 Reply 1 reply Stern Cawthray Stern Cawthray 2 years ago We need quantum computers to work out these calculations 3 Reply 1 reply Hermes XIVV Hermes XIVV 1 year ago I think a few hundreds of years from now once we actually have the technology it can be a real possibility Reply 1 reply Mike Mike 1 year ago (edited) Every bit of energy lasts forever now.

But the best thing is, when time will be slow for you, you won't even realize it. You'll feel as it is regular time. Unless you travel back with the same speed, you won't even realize the diffrences. Actually we travelling much much higher than the speed of light. Because space expanding itself at the speed of 3 billion trillion kilometers per sec.

Otherwise the effect of us going back in time would enable us to look into a telescope and see other parts of the cosmos as they too would have been seen before we left. My guess would be that the only way to travel back to a point in our past relative to ourselves is still not possible.

Reply Matthew Matthew 1 year ago Going faster than light you just beat the light to a specific destination and can look back at the position you departed from and see the past... Traveling back to that point you catch up with the light until it presents nothing but the present and are met with the same amount of time passing as the entirety of the time it took to make the trip. With it being "impossible" to travel faster than light you will never observe this in reality. I have no input on the gravitational effect on time but seeing as Gravity isn't fully defined it may be an opinionated view that is not possible. I do not think FTL travel is equivalent to Time Travel or better put "4th dimensional" travel but if Gravity can be manipulated then maybe there is merit to the idea. It's quite the conundrum and could be a theoretical fallacy based on imaginative ideals. The Grandpa Paradox isn't much of an issue... once you exist you won't fade out of existence due to killing your ancestors BTTF style. The future you exist in is set no matter if the actions you take are corrected or not but a new future can exist along side it and you in turn become "interdimensional"... sounds relatively silly but so does time travel. It's a theory to be tested of course when and if technology permits it depending on a participant willing enough to try it out. I believe Many Worlds Theory is a good base to interpret this but therein lies the prospect of a whole mess of different futures interfering with the current present we experience now. 1 Reply Nwachukwu Oluwadamilare Nwachukwu Oluwadamilare 1 year ago I discovered the answer to time travel,we can only travel into the past not the future that is why most of the prediction of the future by many scientists have failed because the future is limitless I got this through my new discovery of how the universe came into existence 1 Reply Clientes Informações Clientes Informações 5 months ago Since someone predicted my future, I am sure we are living the past and at least people from the future can communicate with people in the past.

Speed affects time, and gravity affects time. But what if these are both one and the same? Gravity is of course pulling us in a set direction, and everything is constantly moving. We understand speed and gravity as they're defined, but how do we know that the 'speed' has to actually involve moving? Gravity pulls us down to the Earth, but we aren't moving because we're on the ground. What if, to the laws of space/time, the force of us pushing against the Earth is regarded as both speed and gravity? To better explain, imagine being on the verge of being pulled into a black hole. You're right at the sweet spot where the force pulling you in is equal to your exit velocity, keeping you constantly at the same distance from the black hole at all times. You're moving, and also not moving, at the same time. You're being pulled in, but also pushing yourself away, and remaining still. This is probably something that holds no significance to the matter, but I found it interesting to think about. Anyways... The Earth is constantly rotating at an incredible speed, as well as orbiting the sun at an even more immense speed. The sun is also orbiting the black hole at the center of the Milky Way, and the Milky Way (i believe) is also moving throughout space. We're in a constant state of movement, no matter what. Which also makes me wonder, if speed affects time, then what would happen to something that is 100% still in space? 7 Reply Willj265 Willj265 1 year ago Sad thing is we will never be able to harness time travel backwards because we would already know about it from time traveler's Reply Nick Steadman Nick Steadman 8 months ago Even if time travel to the past was possible I don’t think our bodies could handle it.

So the way I took this is time traveling and parallel universe could co exist in a mysterious way. 1 Reply Bobby Starkey Bobby Starkey 1 year ago I'm moving forward in time now Reply Don Juan Don Juan 1 year ago If all energy is never destroyed only transferred maybe one day all the signature of atoms could be collected,Identified,And then therefore revisited 4 Reply Bang Broch Bang Broch 1 year ago i'd like to imagine that time travel is very possible in the future, but we can never change the past because everytime we do the jump to the past we are not actually going to our past, but we are going to our parallel reality past. so if we change something, the one that changed is another reality's future and not ours. the reason why we dont see any time traveler from the future in our present time is because its highly classified ( i dont know if this is the right use of word) just like not everybody could become an astronaut so does time traveller.

Reply Miguel Rosado Miguel Rosado 2 years ago Time travel is not possible. To travel back in time you have to put every particle in the universe back where they were at that particular time, to go to the future you have to put every particles were they are going to be at that time. Time emerges from movement (energy fields)t and space. No movement, no time. We can perceive/measure movement thru space so our notion of time is formed. 4 Reply 1 reply Rique Jb Rique Jb 1 year ago If you travel to the future and come back to the present without changing anything in the history of Earth you actually travelled back in time Reply 1 reply FunLightFactory FunLightFactory 9 months ago (edited) I would think the laws of probability are separate from the space time continuum. In other words, if you observed lottery numbers being pulled, the numbers chosen, say, have a probability of 1 in 250 million. You go back in time and play those lottery numbers, however, the lottery numbers pulled are still 1 in 250 million that the same number would be generated. I would be curious to hear from a physicist theory on that. Time travel scenarios always seem to ignore the laws of probability. As they say, "The roulette wheel has no memory." If there's a 1 in 5 chance, there is always a 1 in 5 chance. It seems like no matter what, you will always have the "Grandfather paradox," because if you went back in time didn't change a thing, and then went forward in time, you're pretty much "reshuffling" the deck. You would come back to a reality that isn't the same, because every probability would be re-done.

The brightest mind once said we’ll never fly, it’s impossible. There are thousands of things we have now where the brightest minds said it was impossible. So I’m going to allow my dreams to flourish and know one day instantaneous travel both forward and back through time is possible, warp speed is possible, travel through and into higher dimensions is possible. Creating a machine with a screen that allows you to talk to our dead relatives is possible. It’s all just about using your imagination. 1 Reply random user random user 1 year ago Wasn't he explaining that to a grade school? They walked out like wtf?

You're aging faster. That doesn't mean you're going to end up in a future timeline. Cause unlike the fiction, the future hasn't happened yet (from your perspective). Similarly if you use two black holes you're effectively slowing down the flow of time around you. Therefore when you come back from it, you'll be nearly at the same age as you went in, but the universe around you would've aged a lot. This scenario actually makes traveling to the future happen, but it's permanent. Reply ChewGummy ChewGummy 1 year ago Okay, I'm pretending that I understand some of it.
