@nils4545 I wouldn't want him as my plumber. He'll probably tell me that my toilet doesn't work because of the hologram projector at the edge of the universe.
You're absolutely right, and Bohm is still not getting the credit he deserves, not only as the foremost pioneer in the territory of holographic reality, but as one of the greatest thinkers of the 20th Century, not to mention his ballsy activism as a political exile for refusing to be a narc in the HUAC witch hunt.
*Summary* *Hawkings:* Black holes empty the Universe's Recycle Bin. *Susskind:* No, black holes copy and paste all of the files and store one set in a back-up folder. *Hawkings:* Control+Z.
The faith shattering truth... We still don't know what we are... We still don't know why we are... We still don't know where we are... Totally mind bending...
TheDruidKing Yes, I can see it now, John Malkovich verbally “bitch slapping” Stephen Hawking... JM...(voice starts low) I’m sorry, but I must vehemently, in no uncertain terms, disagree with your godawful “once anything goes inside a black hole it is eternally lost“ theory. (raises voice a little and gesters) No offense, but it is the worst crackpot unscientific POS I have ever heard since the day I first heard about “eternal hell for sinners”. (Raises voice more while gestering more emphatically) How could you, of all people, buy into anything even remotely resembling that fairytale nonsense?! (voice getting ever louder, with f-bomb at the top of his lungs, then starts to go lower) ONLY AN ABSOLUTE MEDIEVAL MORONIC MIND...FUCK!!!...WOULD ENTERTAIN THIS ULTIMATE RELIGIOUS HORSESHIT!(lowers voice) So how could you as a scientist and an atheist, and presumably the world’s formost modern day representative of the age of reason, believe and teach the atheist scientific equivalent of “eternal hell”? SH...(synthesized computer voice)... I never said or implied that there was an “eternal hell” inside a black hole, only that once anything enters it, it cannot return. We do not know what is on “the other side” of a black hole. For all we know, it could be a much better world, certainly better than a world where it is possible to be shriveled up with ALS, cooped up in a wheelchair, having to be fed and bathed, and having to speak through a computer for most of your life. To the average person, if there were an “eternal hell“, that would be it!
I learned general relativity in high school by watching his free Stanford lectures. Ever since them, whenever I need to understand a physics concept, I've always gone to him. Somewhat ironically, or perhaps expectedly, he is the one leading the revolution in quantum gravity with conjectures like holography and ER=EPR. You said it best, mjlv.
I'm extremely glad there are people out there that are capable of understanding these theories, and furthering ideas such as this. My brain hurts, but I want to learn it.
Thats it brother atleast you want you to learn so keep it up .If you never try you will definitely never but if you try you may learn atleast some of it
Susskind's point about the difficulty in explaining complex ideas of quantum based physics was very enlightening. Lowers the frustration of not understanding certain concepts even though I'm good at learning most things. The retraining of thinking in terms of mathematics from natural intuition, makes complete sense.
Yes, he is right about that. Nobody is born with understanding 4D space-time or quantum mechanics. It's an abstraction that must be built-up by effort and experience. If you do like this sort of thing, i can recommend something: Susskind put lectures on yutub for continuing education. Everything from quantum mechanics, particle physics, Relativity, to Cosmology. They go in order from Classical Mechanics on up. Very comprehensive, and only use calculus. No esoteric math. It's an amazing resource, and it's free. Search his name, the lectures are on "Stanford" channel. Just like you said: you need to spend some time immersed in it to get a better understanding. You have to get in over your head if you want to learn to swim. He does a masterful job with these lecture series. There's also the "Theoretical Minimum" series, which hits the basics of what theoretical physics is. Susskind really did society a great service putting these lectures in the public domain for all to see. I am telling you of this because you are right in your assessment of what is needed to understand the topics. You're ready. Cheers.
I'm struggling to find words to describe how great these videos are. You guys delve into these subjects with such open minds and really try to show us the bigger picture. Can't believe I've only just starting watching them after being subbed to Craig for years haha. Thank You!
Great video with a Modern Master of Physics Susskind! Loved his vibe, and brilliance! The saddest part of life is getting old and dying and not be able to do more. Salute to the modern greats.
I am one of these people who does not understand the rigirous math work but am fascinated by the answers. My response to the breakthroughs in physics is "That sounds great on paper, now what are we going to use this knowledge to build? Let's figure out a way to implement this hologram principle into a device everybody can use and benefit from much like the computer, smart phone, or automobile."
I've seen hours and hours of Susskind lectures and I love them all. Although I have gone beyond this video content on this subject, it's very cool to see something so light and upbeat about it, and also very well encapsulated and simplified.
Prof. Susskind has presented a wonderful series of lectures on quantum entanglement at Stanford, available on RU-vid. He starts at high school British 'O' level standard and in a few hours walks you gently to the math of quantum physics. Prof Susskind if you are reading, thanks and please, if you are still presenting this material please re-record in high quality video.
Can we all take a moment to appreciate how nervous Craig was during that interview? You can really tell how much he respects and admires Susskind(as many rightfully should)
I think a good analogy for extra-dimensions would be color--or sound. We evolved to see only a small part of the electromagnetic spectrum. Yet electromagnetic waves we cannot see exist all around us. Likewise with sound. Perhaps extra-dimensions exist in a similar way.
I think the problem is that this video states most of these ideas as fact, not unproven possibilities. This is probably because the entire video refers to only one scientists. But the general content is very interesting.
if what he says is true you would find it everywhere, as what you call metaphor. projector and a screen. allegoric of the cave. so you can prove it to yourself. yet it does not discredit anyone else, the universe is big enough to accommodate everyone. how does it feel?
Vimple You'd have to ask Dr. Susskind to be sure but I believe the interaction between the hologram and the projection is instantaneous. Probably because they're not bound by "normal" space-time. We'll probably address this in the comment/response portion of the next video.
In short, yes. Your hologram is as far as your sphere of influence which would be at the speed of light. So your birthday with the amount of time you've been alive in seconds multiplied by the speed of light would theoretically be how far your hologram is. It's a pretty genius way of getting around the information paradox.
LeeviON ***** I study general relativity, and one rule is that nothing happens instantaneously. If the sun magically disappeared, the earth would still keep circling around until the second it became dark, because information travels at the speed of light, and the earth would fly off like letting a ball with a string go. Along with everything in the universe, information cannot instantaneously move somewhere, it has to travel there as fast as possible which would be light. That's partly the reason why we had to create inflation for cosmology for something called the horizon problem. Because the universe is so uniform, there was a paradox in which it would have been impossible for information to travel across the entire universe from one side to another and communicate that everything, density and expansion and heat, should be almost the same. Your horizon is because how far you can look into the universe, also called the observable universe because the actual universe is something like 30x bigger but we can never see it. Because information can't travel instantaneously, you have the horizon problem so they got around it with cosmic inflation.
I have watched a couple of other presentations with Susskind. He is most aeticulate and affable, and makes physics easy to understand for the rest of us non-physicist types.
I have the feeling that not only what is happening now is stored somewhere but so does every experience that i've ever had in my life is stored somewhere. So it's not just in my memory but actually stored somewhere and actually "going on" right now.
For people steeped in Vedic philosophy, this principle would not seem so weird. Science as we have known it has entirely relied on our senses and to think that reality could extend beyond our senses has not been in the realm of modern scientific beliefs. For instance, science does not bother about any notion even remotely related to post-life issues but that does not mean those issues are irrelevant.
Susskind's explanation of why these ideas are so complex and why math is intrinsic to that complexity is beautiful. I will have to point someone to this playlist next time I'm asked why college students are so often required to take mathematics.
I'd be pretty excited to interview Leonard Susskind! Thanks for making this video and sharing it! Very nice outro music, good to ponder a little what has been said.
Thanks guys, great interview. The way i see it, we can learn a vast majority about physics and how the world works by learning about the concepts. But if one wants to be able to do any calculations and predictions in physics then that is where the maths comes in. I am terrible at maths but pretty good with the concepts.. Susskind obviously is excellent at both ! :)
I loved Susskind's response to the comment that Hawking was simply wrong. He could've let his ego unchecked and trashed Hawking. Instead, he gave him huge kudos for being perceptive enough to shake the physics community and ask the question that led to all this. I also loooved the cut to Juan Maldacena when he was praising his realization of the Holographic Principle.
"Through evolution, the neural wiring that we inherited was not built for quantum mechanics. It was not built for higher dimensions. It was not built for thinking about curved space-time. It was built for classical physics." This resonates well and captures the 'human condition', such that it is. For us to achieve more, to continue to evolve if this is truly our direction, we must perhaps build a system greater than us to achieve it and A.I. is the dawn of this.
That's what I think of every time I hear about the hologram theory too It's also away we can at least try to comprehend that there are more than three dimensions so I call in because we are living (?) 3D shadows!
Lets make a trip into the platonic realm of forms. just follow me into the black hole and you will see MATHEMATICS, the first rational emanation from the absolute. With mathematics, the sacred geometry of our reality can be understood. Yes, Yes welcome into the dark side of physics.
Much appreciated. Siskin makes an extremely important observation. People are resentful because they do not comprehend the math. The fact that only a few people actually understand the math, doesn’t help...
So if our three dimensional reality is a hologram projection at the event horizon of a singularity or black hole, filled with information from higher dimensions, it is interesting to think about the nature of our conciousness from that perspective. The incomprehensible subjective experience as a projected, granular artefact of a higher principle of conciousness.
As a person who believes that he is God I like the idea of contemplating myself from different dimensions. Since I am God and the whole universe and everything in it I know that there is no past and no future, only the now. A series of nows, a life, death, rebirth and then it starts all over again. Or maybe you get off the wheel and stay in the Godhead and learn, grow. The only constant is change.
Many people say we are not necessarily limited to our '3D-neurological-wiring, and, that there is another way to apperceive the higher reality (the source of this hologram), other than mathematics (which is also valid). The first person I know of to get the idea of the holographic nature of this 'reality' out to the public, was Michael Talbot, in his book: "The Holographic Universe" - in which he quotes scientists from many different fields (not just quantum physicists), including neurologists. He also quotes many studies by leading universities on: out of body experiences, near death experiences, remote viewing and others who are able to see a higher level of reality - to directly tune in to the vibrations that are the basis of all mass. He first published that book in 1991.
This guy is a Prof at Stanford, pioneered string theory, worked with Feynman and runs quantum physics 101 lectures for dummies off the street as a sort of night class (which are recorded and published on youtube for dummies like me). He's a good egg, listen to one of the above mentioned lectures and you'll understand why, has the patience of a saint.
Wait. so. black holes are super dense. so why doesn't all the atoms from the stuff sucked in just stay at the black hole but just really hardly packed?
+John Matthews They do for a while, but what Stephen Hawking discovered was that black holes slowly evaporate until they eventually disappear. This is called Hawking radiation. Originally Hawking's theory implied that all the information is lost as the black hole evaporates. The holographic principle is sort of a work around solution to that problem.
well his analogy is somewhat incorect. information is basically could you tell what fell into a black hole? on the event horizon photons continuously orbit at escape velocity. so you would continously see two dimensional cross sections of . there is no way of saying that an exact replica of you is created. you could tell which matter has entered by the energy of the photons etc.... it's like saying a life sized poster is a replica of you. black holes are so dense that they warp space time so much that it folds in on itself. because you can't pack that much matter down to a pin head. you yourself are even 95% empty space the space between the electrons and nucleus the nuclei are practically empty except for quarks and they are practically empty. even 95 % empty isn't enough to account for the density of a black hole but it folds space time into multiple layers, so you can fit more matter into a visibly smaller space.
+The Good Stuff So, if the Black Hole slowly disappears, where (and "how") is the information from the event horizon then after the Black Hole is gone?
Some topics in physics really deserve a big red label "we can't really explain it without math". Right now there are probably millions of laymen running around saying and thinking that everything is a hologram, without understanding anything about the topic at all. I'm sure the explanation somehow aligns with math, but for those who don't understand the math involved, the explanation given doesn't really explain anything at all, you don't come out the other end understanding more about the universe. Quite possible that you are more confused and actually understand less. Some things can be explained without math, some can't and should be left at that.
this helped me alot let wrap my head around some more "Hard" theorys and stuff. and where you said that no one is right about the future. made me cry. thank you for that.
Most of us are not wired to experience 4d, 5d but only for 3d, based on classical physics, what a man Susskind is , I was always a quantum physicist, is a killing statement from him. Amazing Human. Interviewers are really Good Stuff, thanks for this beautiful interview.
Funny thing is, us who have gone deep enough with psychedelics already know what the universe is and what reality is. While scientists waste their life chasing a measurement from the observers perspective.
@@fridjon13 So, where are your contributions to science then? Where are your particle accelerators and space agencies? You clearly have no idea what you're talking about.
2 x 2 = 4 -2 x -2 = 4 If you take the square route of 4 then you get + or - 2 you can never know which. You may be able to burn a book but you can never go backwards because even though you have the original elements there is no information to tell you how each of those elements were arranged and in what order.
Vinay Seth - The brain is a part of the universe experiencing itself, and it's tuned to experience the parts of the universe that is useful to the survival of its owner's body. If you tune the mechanism a little differently it will perceive the universe in other ways.
Cosmonauteable Define "deeper". I don't know about your chemistry, but my chemistry, actually my whole body, is composed strictly of elements of the universe interacting in a pattern that allows it to experience the rest of itself from the viewpoint of an individual I call "me". There is no individual me distinct from the universe. I am the universe. And so are you. Is that too far out? To say "it's just chemistry and electrical impulses" is to downplay how amazing the concept and physics of the universe is. It can create every object, thought, feeling and experience we know in this human experience and all that is to come in the future. I find that to be mind bendingly awe inspiring. In fact it's so wild that to even function in everyday life, we all have to apply a shroud of mundanity to the whole thing. Some people are TOO good at this and they end up seeing biology and existence as something mundane. I'm afraid you've fallen into that trap. I'm not saying the the opposite, ultra hippy view is much better. There has to be a balance, and for me, that balance still gives room for awe.
01. From a Physics perspective the atoms that make up the paper and ink and letters…….. Would still be there and could theoretically be recombined if we had the right tools. 02. The entire three dimensional spaces is a projection of very distant horizon that surrounds us…… so you could say that we on the inside of it are a projection of this film like things that's on the boundary of universe.
If we accept the concept of the holographic universe as a fact and not just a theory. How does this has been programmed? Who did it? Are we going to get stuck again questioning whether it came by itself after a big bang OR some almighty power created it?
nhaar Not so fast here's something which I think it's impossible, ready here we go if were living in the simulation how do we know? how do we know if the person outside of the multi-simulation is real? what if the Aliens or humans who are running the multi-simulation realize that they are part of someone else’s multi-simulation and then the next one and the next one and the next one and the next one? we don’t even know if this could be a possibly that we’re living in a simulation, because we will never know who is our true creator because it’s impossible to know if he or she or thing is real or not, because How do we know if the person outside the multi-simulation could be real? how do we know if they’re not part of someone else’s multi-simulation, so therefore it be impossible for us to be living in a simulation, either if humans or aliens are simulating us or where being simulated while we’re playing a game, how do we know if where in a multi-simulation, if the person outside of the multi-simulation is not part of someone else’s multi-simulation, How do we know if it’s true, how is it possible, we will never know? That's why I think it’s impossible for us to know if we’re living in a simulation, because our creator can't be created out of nothing, even if there's people from other dimensions then what are the odds that they don't know if they are part of simulation, now people said that someone or something who made the simulation is coding this so he would want us to think that way, but how do we know that the person who is coding this, how do we know if he's not being coded as well, for the people who are seeing glitches in real life. In my opinion it's either demons or aliens who can break the laws of physics in our world, the devil can sometimes trick your mind into thinking reality isn't real or aliens can do the same,
Reality being a hologram projected onto a 2D surface, for us, wouldn't actually make anything less meaningful or less "real" to us in any significant sense worth worrying about, in my opinion. (Yea, I know, Gravity Falls reference.)
Easy.......... look at a video game. you are playing in the center of the screen. as you move your characters to the left all the other characters seem to go to the right until they are off of the screen. If you keep going to the left the characters will go so far right there will be very little or no computer resources dedicated to that character. It would be standing in limbo with no background. Now lets take you. You know people who know people. If you walk or drive somewhere where you are away from interacting with any person you might notice that your surroundings are breaking down and will eventually look like the Holosuite on star trek the next generation, just a grid pattern. I have had this happen to me twice and I have had a car drive right through me at an intersection at 3AM on a tuesday night. There wasn't even wind that morning. Many people have seen ghost trains and had real trains drive right through their cars without injury. The computer program is breaking down at it's outermost edges.
Feeling lighthearted today, after a long time. One question: so if our universe a hologram within a black hole with info on the horizon surrounding us and within this exist other black holes - does it not translate to a telescopic set of black holes? Nope, not smoking.
While I can't comprehend this. I really can't. I have really come to understand just how meaningless everything is. I don't mean this in a bad way. I mean that nothing has any meaning.
elocifer I have no problem accepting nothing means anything. In fact that's quite comforting. The only meaning we have is the meaning we arbitrarily assign to ourselves and the way we perceive our reality. Which for all intents and purposes, is intrinsic meaning.
Susskind is brilliant and a magnificent example of systematic critical thinking. The guys hosting the video are great too!, Specially when dramatizing our intuitive relation with nature (from 10:08 and onwards!!) Congratulations you all!!
I'm trying to keep an open mind about this. I keep going back to "How does he know?" Because an alarm went off when he said that he knew Hawking was wrong, but didn't know how. The methodology is more important than the conclusion and he didn't seem to accept that. It is hard for me to accept the projection theory if I don't know how they arrived at that conclusion. Lesser notes: I cringed when you guys said, "Kids, don't do drugs." Maybe instead, you should've said, "Parents, don't traumatize your children." This would be addressing the problem instead of trying to manage the symptom. It would be more efficient too since peacefully raised children wouldn't only not have a need for drugs, but also wouldn't be prone to other addictions, wouldn't be romantically unfaithful, wouldn't accept artificial authority, etc. The science is in: We know that the root of pretty much all man-made ills in this world stem from trauma in the formative years. You do get points though for pointing out that we should recoil from those who claim to have all the answers. It is sound wisdom. If only people were NOT abused as children enough to be able to hold the same standard to politicians for example.
As a non-physicist trying to understand such things I have a question or two. The statement is: *"Information (distinctions between states) is lost when it gets trapped in a black hole"* But this seems ambiguous. It could mean either: (a) "Information (distinctions between states) is _lost to us_ when it gets trapped in a black hole but continues to exist _inside_ the black hole" _or_ (b) "Information (distinctions between states) _ceases to exist altogether_ when it gets trapped in a black hole." Now my questions: 1. Which of these, (a) or (b) is meant? 2. Would it only be only under (b) that we have a problem that Susskind addresses? (Because under (a) there is no absolute loss, only loss with respect to us. Can anyone out there help?
Information appears scrambled to the external observer. The guy passing the horizon feels fine and experiences life as usual (until they hit the singularity) because they are "projected" on to the interior of the black hole. The compressed information on the boundary of the BH (the hologram) is all the external observer can see. You might want to look into the AdS-CFT correspondence if you really want to go deeper into this.
