Mark Van Raamsdonk is a brilliant physicist. His idea of unifying classical physics and quantum physics via Susskind's and 't Hooft's holography, Einsteinian classical gravity and Einsteinian quantum entanglement to explain the structure of spacetime is the biggest leap forward in this area since the establishment of QED in the 1950s. No wonder Greene expressed his feeling of awe and applauded this work. Van Raamsdonk is a Nobel caliber physicist.

Nostra Damus I agree, I enjoyed his interpretation very much, "...an entangled universe. "
Exactly Brian forget to mention that Louis de Broglie predicted all of this in 1923. He PREDICTED quantum diffraction waves as quantum nonlocality and he explained WHY it was happening. Not Max Born. So Now they come back to add in relativity. But de Broglie already had relativity in the model. haha. Hilarious. Astrophysicist Paul S. Wesson acknowledged that de Broglie had figured it out - and so Wesson realized the correct model. He didn't get the credit though - oh well. Also B.G. Sidharth should have got the Nobel prize - and he figured all this out. Even Fred Alan Wolf in his SpaceTime and Beyond book - predicted the same model.
@aaroncurtis8545 5 yıl önce
I agree, that is amazing! And I've been so into Susskind, and that Raphael something guy. Then this guy is next level. That was a mind blow. Ever heard of a book called The Universe of the Mind? It traces the history of the mathematics and physics in a very 'purely the ideas' way. My point being, it definitely needs to be updated with this concept.

41:20-45:50 (Gerard 't Hooft) and 1:15:15-1:15:20 (Mark Van Raamsdonk) : Cannot agree more ..., really appreciate their humbleness compared to most others .... Despite all the hype and at times the fake exaggeration going around / being propagated around by various media too, we got to accept the fact that we are still very much at the infancy, or at most at the level of adolescence, in terms of comprehensively understanding these highly complex systems/phenomena. Modern Science and Quantum Mechanics as part of it may be the best option we've got at this stage, true, still it remains very much immature to cover these aspects in sufficient detail which are beyond our physical/empirical reach too more often than not. Be it Classical Science/Physics or Quantum Theory/Mechanics, all these are just models we have developed with our pretty limited human perception to understand these natural systems/phenomena which may have existed for trillions of trillions of years (or even longer ...). To put things into perspective, we may not have lived at least even 50, 000 years as of now as a (developed) human civilization, our so-called Modern Science may not have any of its roots beyond 5000-10000 years, the majority of our Classical Science/Physics have been developed over the limited time span of last 500 years, our study of Quantum Mechanics has a history of less than 100 years; nothing but an infinitesimal(s) comparatively !.... It may be true that these are the best options we have got at the moment, accepted, but that doesn't mean that these are accurate enough and we are in a position to fully explain all these complex systems/phenomena by using them. Yes, we may keep improving on our understanding/knowledge and get closer to the reality/truth by refining these quite primitive/immature models we've got at the moment, still we might never be able to get to the 100% objective reality/truth ever to interpret all these naturally-occurred highly complex systems/phenomena perfectly .... The (objective) reality/truth is certainly more complex than most of us can even imagine let alone understand, sometimes it may be stranger/weirder than even the strangest/weirdest thing which we may be able to imagine/grasp/understand with the limited system of perception we've been given by nature .... Yes, we humans stand head and shoulders above all other species here (on earth) in terms of intelligence (as per our understanding and definition of it ...) and all our achievements too, still we're only one part of nature and not vice versa, so the human evolution has not given us everything despite how remarkable it seems comparatively .... So we got to be pretty careful/skeptical in interpreting the observations based on our limited, at times oversimplified too, perception/argumentation/knowledge .... Yes, we may improve over time quite certainly and get closer to perceiving/understanding the (objective) reality/truth, yet we still got to keep in mind the fact that we may get only closer but not quite reach there ever .....

One of the best lectures I have watched so far. Things were easy to understand up to connecting the quantum theory to the black hole. At that point I thought that maybe we could put entangled photons outside and inside the black hole to tell us what is happening inside the black hole. But me then got lost in the idea of wormhole and how entanglement became a thread to connect everything. Will rewatch and thank you very much for the lecture
@THEWIZARDDK2 9 aylar önce
think of the big bang. something can not come from nothing. so when you see the universe as we humans tend to showcase it like a tube. then the big bang is in one end. but behind it. is the universe in reverse. without the multiverse theory involved. a 2 side universe. like black & white holes. although we havent really seen a white hole yet. but in theory they do exist. its truly an advantage if youre into music to understand. because as a dJ i always have 2 thoughts one for each deck. think of a blackhole like this too. like a battery. you got a plus and a minus. but the battery in the middle is the wormhole that connects the 2. or reject it. always 2 options. or 2 solutions. did you never get this told in life? you can choose to do everything in 2 ways. well i hope i made it more understandable . its basically why humans live wrong . because we tend to make all the easy and wrong choices. but life is not meant to be easy. this is why we wont survive in space without a suit. in such a hostile environment, you cant expect it to be easy to understand either. look beyond humans. that could help too. think like an alien even it sounds bizarre. but it does make it more easy to understand these things. just my bid on making it more easy for more people to grasp. didnt mean to offend or anything. but humans are infact pretty dumb. we are below being kids in space. we are like a sand grain trying to understand everything in the entire universe. search multiverse zoom and watch the video that begins with a firefly. then you know what i mean i think. good hunting :)

I really dig Brian Greene’s style. He is very good at reeling in the discussion and keeping things focused, then translating complex ideas into intuitive analogies. Some people say he interrupts too much but I disagree, without him the discussion would spiral into confusion for the average viewer.

Brian Greene does it again. He pretends to be the one in the panel of experts who does get it in his humble way so we can all feel better about being part of the subject and then he transposes everything the panel members say into something we can all understand. He can distill all of it for us. He has the unique ability to be the frame that holds the window we are trying to look through. I am no scientist nor am I an expert but Mr. Greene allows me in particular to enjoy being curious about all of this.

Watching the graphics now and it definitely helps you comprehend better vs using this as a bed time story/car ride.

I like virtual particle pairs. When one particle passes through the left slit it has a chance of annihilating one virtual anti-particle, whose virtual partner has a different random trajectory, and path length, towards, or maybe away from, the target screen. it may also collide with a virtual particle. The scattering of these lead to further collisions resulting in a probability cone from the left slit together with, some particles arriving at the screen at different places and different times. There is a corresponding right slit probability cone, with the opposite direction and collision or annihilation pattern. The energy of the particle beam and the slit separation, together with the distance to the target define how the emitted particles and virtual particles interact on their way to the target screen, and the interference pattern is just the resultant pattern of particles striking the screen, with antiparticles and apparently deflected particles being annihilated between the interference bands.
Thank you, for sharing quantum mechanics to the public. I think, one day I might be able to wrap my head around it, but I think, 🤔 it's unlikely. However, I can take it in small doses, because, I'm really interested.

When it comes to quantum entanglement, the experiments I ask the question how much time passes for light, we see the light zipping around the experiment, but from the point of view of the light is leaves and arrives at the same time. The way it’s packaged at the beginning of its journey is how it will be unpacked at the end, and the entanglement is formed at its origin.

When I was a kid and a teenager it messed me up quite badly. "Many worlds" idea expplains quite well the messed uppness of politics if you give it a change by the way ;) All the possible worldviews and opinions out there are able to exist because the people and groups of ppl really live in different realities.

All I gotta say is this the double slit experiment works exactly the same way radar was discovered and modified and electron is thrown through a chamber goes past a cavity creating microwaves which then get deflected out in a wave pattern creating radar as we know it it is called a magnetron radar that we still news to this day‘s most scientists would not know this because it is a very secretive and you gotta be in it to know what I say the double slit experiment is creating the same effects as a magnetron radar very easy to test but there’s a lot of resistance yeah only difference between the double slit experiment in a magnetron is that the electron continues on its path opposite the cavity which is creating the magnetic wave which we news as radar the electron gets recycled back through and is a feedback loop double seed experiment doesn’t the magnetic disturbance is going in the same direction as the electron your only difference between the two so if there was a magnetic disturbance Creating a radar affect in the same direction of the electron itself it would be carried on the wave and pushed around which opens up the world to a lot more possibilities if we can push and electron we can do a lot of different things hence why there is a lot of resistance I can say this because I am in the field of discussion Think about it if any electron in the double slit experiment demonstrates that we can push electrons pause for a second think about that

The negative and positive parts of the photon, like a double sided image (referring to the double slit experiment). Where it lands depends on precision of the alignment between the laser and slits. In a question form maybe but this is what I think. And distance playing a part. Measurement changes the particle chance of landing at a certain location. If particles can be tracked the probability wave could be flattened for longer periods with measured from the origin

Brian Greene is da man -- the adult equivalent of Bill Nye the Science Guy. I am terminally math-impaired, yet deeply interested in both relativity's time/space counterintuitions, and quantum mechanics' weirdnesses; Greene seems to intuit workarounds for mathlexics like me, so that while I can't "math" it, I can indeed "picture" it. And his moderation of this assemblage of heavyweights was, in addition to being pitch perfect, also a demonstration of his grasp of the cutting-edge boundaries of physics in general. "They also serve who stand and wait -- and moderate."

Just love idea of being both and or or. And possibly adjusting our consciousness we can explore both. Hence communicating with others throughout the universe.

This is exactly what I needed on a Sunday afternoon. So grateful to be able to understand what was discussed and appreciate the dedication of physicists through the years. The particalization of the wave is meant to prohibit the wave of connectivity with each other and our enviroment, which is how we evolved, as a social specjes This connection with everyone is harmonious and the introduction of the "ego" and the concept of "I", rather than, "we", prohibits this connection we've evolved with and limits us and allows us to be managed. When you work and earn money, that is the particalization of the wave. The digitization of the experience. The multidimensional expressed in a foreign, two dimensional "binary" code representation of consciousness and connectedness is suppressed by division, competition, concepts of "race", "us vs them",(such behavior perhaps served an evolutionary purpose and avoided introducing foreign pathogens to various tribes?), but they even describe it in the Book of Genesis. The serpent is "self awareness", and the concept of, "All this "we", what about "me?", is introduced and suddenly then they need clothes, Cain kills Able, everyone got wicked and started polluting the genetic purity of Homosapiens and Noah built his ark and God flushes the wicked away with the flood, and the rest is experienced as an invisible servitude burdened by foreign concepts and ideas perpetrated upon humanity as a means of control and the constant push to impose the digitization of our analog consciousness.

van Raamsdonk's recent research (quantum entanglement as the basis of space time) is by far some of the most interesting stuff in a while in physics.
Why the proton entanglement can not be explained by the electromagnetic field? Like the positive and negative that always go along with each other and cannot technically exist independently to create energy? Sorry if my question is irrelevant.

@@FriendlyPerson-zb4gv As I understand it, one reason is that electromagnetic fields propagate at the speed of light, while entanglement is instantaneous over any distance. Also the propagation of electromagnetic fields involve photons (a boson field carrier "particle") and there is no such exchange of energy in entanglement.

1:26:26 for me one explanation for this so called quantum superposition could be caused by : a rapid oscillation between one state and the other. This would be coherent with the apparent perception of superposition of states. This could also explain the quantum entanglement. In any case how can anyone be 100% certain that the particules are in both states at the same time... As I set before: this could be a possible logical awnser. 💪(the fast oscillation : maybe even close to the speed of light) Although I could be of course misinterpreting this strange phenomenon... 😕😌

I'm confused as the double split experiment they carried out here actually showed the interference pattern meaning the photons were behaving like waves, but there were many observers there so how come this could happen? Wasn't the wave function suppose to collapse by the act of observing..?

I was quite surprised to learn that the double-slit experiment was first performed at the turn of the nineteenth century by Thomas Young and presented to the Royal Society in 1803 as part of light diffraction; cool drawing he did, then. An explanation of that is still what I would ask famous smart guys if I had the chance.

A Tale of Quantum Physics When I retired a few years ago after forty some years as a physicist/scientist/engineer/college professor I decided it was time for me to develop a solid understanding of quantum physics, a.k.a. quantum mechanics. I mean how could I call myself a physicist if I didn’t know all there was to know about such an important subject. So over the past five years I spent a lot of time reading everything I could find online about QM. I read about what the most brilliant scientists had to say, from Einstein’s comment “God doesn’t play dice” to Schroedinger’s schizophrenic cat. I read about the electron double slit experiment which gives wildly different results depending on whether the outcome is being measured or not. Some scientists even claim that just being seen by a human observer causes the outcome to switch. Then I read about Richard Feynman’s chromo electrodynamics many-path formulation where every electron has an equal probability of going in any direction . . . until a measurement chooses the observed path. The credibility was stretched even further when I read that Murray Gel-man proposed that every particle was made up of even smaller components called quarks (which always occur in threes and are somehow part of ‘The Eight-Fold Way’); that David Dennison claimed that electrons, protons, neutrons, quarks, and just about every other atomic particle not only had spin (up or down), and Gel-Mann’s quarks came in three designer colors; red, blue and green. And I haven’t even brought up quantum entanglement; what Einstein called “spooky action at a distance.” I finally realized that there was no way I would ever understand it all and fretted about this until I came across the words by Richard Feynman: “I think I can safely say that nobody understands quantum mechanics. If you think you understand quantum mechanics, then you don’t.” None of the “experts” really understood it either. I could go back to claiming I was a physicist! But how could such situation happen? Well, each of the experts developed their own pet theory, but none of the hypothetical frameworks could hold together - be consistent with what we knew for sure. So the creative scientists invented whatever it took to make their theory work. Sometimes it was new (but unobserved) particles like quarks, or immeasurable properties they called spin, color, or an infinite number of multiple paths. So my final conclusion was that quantum physics/mechanics is like the story of the king’s new clothes. Every scientist saw what they wanted to see, while the truth of it all was that the king was really naked.

Has the double slit experiment ever been performed in a void? Just wondering if that would affect the result, like how water waves is a transfer of kinetic energy in water.
Yes it has been performed in a vaccum. Particularly when conducted with electrons (because they interact with air). Still same results.

Just randomly put this on for my intelligent discourse fix, and I suddenly realised that I went to school with David Wallace in Bedford. He was a real geek, on the spectrum, and the brightest kid in the year - but we used to have good chats in the library sometimes. He doesn't appear to have changed much, apart from that ghastly ponytail 🤣🤣. God bless you Dave, glad you found your calling and delighted with your success. Physics was never any doubt, Mr Dixon thought you were the return of the Messiah 🤣
Quantum physics actually provided me with an explanation for my many unusual actual 😉 experiences throughout my lifetime! So wrapping my mind around these concepts is my normal!
I'm hoping I'm wrong, but if you're talking about experiences like "that one time I thought about my friend who was in another country and then they called me 30 seconds later", please stop giving thanks to quantum physics. Truly understanding these concepts is difficult and extremely unintuitive. The last thing anyone needs to be doing is using particle phenomena to explain why they found $20 in a jean jacket at the Good Will.

13:00 because of lateral momentum of the gun (and pellets), the pellets would land in a rectangle that would be slightly wider than the slit, but the same height (assuming the gun only rotates laterally and has no up/down movement unlike the example the video gives). By tweaking the momentum of the system, you could tweak where the pellets land the most, and essentially create an interference pattern. I imagine the more lateral momentum, relative to its own mass, something has as its put through a double slit experiment allows that thing to behave more like a "wave" completely based on what classical physics says will happen. Light has the largest momentum relative to mass, so it most easily and most commonly behaves as such. Essentially, I disagree that it makes sense that classical physics says a double slit experiment will result in perfect rectangles. They're comparing apples to oranges. Light has that lateral momentum baked into it when the experimenters emit it, macroscopic objects don't.
TF you talking about. nice word salad but no. light... is made up of photons, that is light. i don't think you understand what the word momentum means, let alone quantum mechanics lol, im saving this, this is hilarious tho
@sonnenklang6925 Yıl önce
I think we miss out on the fact that in the normal full lights on doubleslit experiment setup also not perfectly sortet and orderly twin couples of "photons"(if there is something like that at all;) pass through each slits perfectly at the same time.. so no big surprise it still works with less photons, i would say the properties of light spacetime and its source define this effect, not their count or if you watch it or not ;D

the idea of a holograph 2d black hole is very interesting as it falls in line with my own ponderings on the nature of our 3d reality. i been playing with the idea that our reality is actually a 2d one, and its a warping of this 2d that give the illusion of a 3d memory. in a single instance like that taken in a photograph we get a static 2d image of the world. we need to move around in order to render in our memory a 3d picture. the now is the static 2d photo only our memory reconstruction creates a 3d impression. we warp the 2d in order to achieve this, which give us the impression of time and space. or you can say time/space is the 3rd dimension! time is memory! which tie into his explanation of black holes slowing time down to the observer and how the black hole is a 2d membrane of information! thats my take on this anyways
