    What's really going on in a black hole? Why are there so many theories of everything? Did Leonard Susskind, one of the fathers of string theory, ever feel like an impostor? And why did he fight with Stephen Hawking?
    Find out in this thrilling interview with none other than Susskind himself from 2020. Susskind is an American physicist and a professor of theoretical physics at Stanford University. He is also the founding director of the Stanford Institute for Theoretical Physics. In 1995, Susskind was the first to give a precise string-theoretic interpretation of the holographic principle and the first to introduce the idea of the string theory landscape in 2003.
    In this interview, we discuss Susskind's popular science book, The Black Hole War, which covers the black hole information paradox and the related scientific dispute between Stephen Hawking and Susskind himself. We also talk about other developments in modern physics and more!

      Well, what do you mean by "information"? If you are asking if the black hole changes in size when mass falls in then yes.. Information escapes the black hole. If by "information" you mean reconstructing something after it's fallen in then I say probably not.

Shows he is not only a talented researcher but also an incredibly skilled teacher. Also, grateful Nick Zentner from University of Central Washington released his 101 classes and ongoing studies on youtube.

    Roger Penrose tells us that information is not lost, but it is removed. all information is imbedded in space time, where else would it be? What changes is the size of space time, but the ratio of information to space time stays the same. For example when information is remove so is the portion of space time that the information resides in, both fall into the black hole. Imagine 10 teacups, in each teacup resides a marble.The rule of the teacup universe is that each teacup must contain a marble... there are no exceptions to this rule. The job of monitoring the teacup universe is given to Lenny Susskind. On his rounds he has to make sure there is no contravening of the teacup rule. One teacup is removed leaving 9 teacups; no rules have been contravened.... all is well, and so on for all the teacups. Lenny does not find a single teacup empty; the ratio of marbles to teacups haven't changed, the universe has not lost information, it has simply reduced in size.
    Roger Penrose proposes this is what happen to information and eventual all information and it equivalent space time will lie behind the event horizon. Of course eventually the black holes evaporate leaving an empty universe of marbles of unmeasurable size.

    The correlation of electrons outside and inside a black hole would be lost. Might as well pass one through a polarizer and the other not.
    Local hidden variable (LHV) math just needs to compare one result vs another without regard to the total, and you get a curve that fits experimental graphs better than the QM cos prediction graph... especially near the 0's where the error bars are highest. ( A+B=2C; A/C+B/C=2; a=A/C; b=B/C; a+b=2; (b-a)/b and (a-b)/a depending on whether A or B is larger; in the case of a quantum experiment in units of quarter-turn, (x-(2-x))/x or (2-x-x)/(2-x) ; ( 2x-2)/x or (2-2x)/(2-x) depending if x > 1 or < 1; where 0 is 0 degrees, 1 is 90 degrees, and 2=180 degrees. ) It's a multi-part equation, but ever so simple. The more accurate the experiment the better this curve fits.
    atomic nuclei are outside of space and cause the curvature of space; things like electrons and photons travel through space, and are not outside of space - I don't see why it's so hard to get to this conclusion. The nuclear cross section of an atomic nucleus measures smaller than it really is - since, like black holes, photons get lensed around the nucleus and only when heading directly head-on into the particle does it really 'see' and react to the forces outside of space. A black hole is really just a super large nucleus, so if an electron falls into a nucleus, is it still valid to call it entangled/correlated with any other electron?
    That two nuclei take a lot of energy in order to actually interact is because space has a sort of surface tension (quantified as the strong force). The strong force between black holes is almost irrelevant though.
    The universe happens to be a perpetual motion machine; there is no absolute tend towards entropy, because curved space causes matter to fall together and become coherent and structured; while at a certain limit that organized matter becomes radioactive and throws itself back out into the universe, only to be collected later. Black holes emit more than just 'hawking radiation'; but I'll save that rant for another day.
    It's too bad he's not more available to toss ideas at; but then my ideas are so foreign they're of course just from a noob who knows nothing about anything, and should be ignored. *shrug* At least noone will scoop my theory before I have the experiment(s) done.

    It's a blessing for Hawking not to experience all these. Otherwise his whole achievement as a theoretical physicist would have come to a waste. Or maybe he could come up with a better theory. So far, I think Roger Penrose is the most reasonable physicist. Rather than proposing a multiverse system, he goes for cyclical universe. We'll never know, but I do believe that there is no such thing as the absolute beginning.

    @51:00 I agree with Lenny about those cultural arguments being unscientific. But (a) that does not make them wrong, and (b) he's forgetting the anthropic arguments are unscientific too, because they rely upon anthropology, they are anthropocentric, violating perhaps the most cherished notion in science, observer independence. (Don't tell me QM is observer dependent, that'd also be baloney, since what QM has is that measurements are context dependent, but that's not observer dependence). Suppose humans never came to be, but all the other life did. Sure, we'd not be around to make the Anthropic arguments, but you can then see there is no "because" - the other paramount principle of science you see, the principle of causality. You cannot throw that one away.
    It'd be sad if a old old school working class leftie turned to postmodernism. But I guess he half has in thinking Baraka Obama is someone to be admired. No neoliberal has ever been a decent politician, left-wing nor right-wing nor centrist. They're all scum of the earth, or, to be charitable, either ignorant or frauds. Are we saying these days you get points merely for not starting too many new wars or color revolutions? Ah... nevertheless, I love Lenny, he's my hero, his wife was feeding him trash NY Times bestseller list crap. Can't be blamed. I was fooled once.

    So Susskind did not understand CCC. A bit sad. Note Susskind validates CCC against at least the entropy problem, since information cannot be lost, Penrose's next Aeon has exactly the same entropy as the previous. Right? The entropy of a cosmological spacetime does not ever change, it is a constant (unless Fred Hoyle was right).

The us patent office is filled with this phenomenon . Also I can no longer dismiss countless other examples paranormal phenomena. The atheist arguments are getting very hard to believe.

    from the relation Frequency=mass=energy , Ive always thought of frequency as fundamental to matter and energy. In this regard I think there is definitely some truth to be gained in that regard, .. Modern string theory as it stand is pretty wobbly, but the sentiment behind it is genious. And if you understand the context, string theorists are more or less trying to find a consistent framework, that gives rise to all the behavior we see on particle scale. If they succeed with this at some point, I think there will be tremendous insights to be derived from the string models.

    Well that's nonsense. I read the whole book and it got me interested in physics. 20 years later, I'm now familiar with Hermitian operators, and fourier transforms, and Riemann curvature tensors and all sorts.
    Plenty of people get something out of popular science books, and in some cases it does lead people to pursue the topic in greater mathematical detail. And for those who just end up having the book on the shelf, in order to impress guests, well... if he got to put his daughter through college, everyone's happy. All seems fine to me!

    Brian, you should interview iconoclastic Prof. Alexander Unzicker, whose physics videos are available at his UA-cam channel Unzicker's Real Physics. Dr. Unzicker is not convinced that black holes even exist. So you might want to have him debate Susskind on the subject. Unzicker is not shy about, in person, confronting iconic physicists regarding their ideas. He has done so with Ed Witten (at one of his lectures) and with David Gross (in an interview).

    Hello from Kazakhstan. We can create an educational and practical device and practically master Einstein’s theories of relativity or obtain, for example, new physics:
    Postulate 1. Light is an ordered vibration of gravitational quanta. Postulate 2. The speed of light, regardless of the source, within the “framework of the dominant gravitational field” This is determined experimentally using a hybrid fiber optic gyroscope (based on Michelson's experiment 1881-2015). Using a hybrid fiber optic gyroscope, the straight-line speed of vehicles can be measured.

    Reality is such that we will never know all, however comprehensible reality is.

Neither is it a mark of greatness to deprive Nambu what credit is due to him. Even though we don't know how to prove divine design, we cannot avoid admitting there was a design, it is a mark of greatness whoever can admit it. Avoiding it is cowardice.

    One thing that most eminent physicist recognise is that the second law can never be overturned…… and observation constantly confirms that.
    So any theory that claims to sideline entropy isn’t based on observation but rather theoretical assumptions.
    The reality is that entropy allows for a dynamic universe which presently causes work to be done and provides useful energy. Without entropy we wouldn’t be here………

      @@joebenham27 The problem is that in the classical definition of systems systems are exchanging energy, momentum, angular momentum and charge with each other. This is what causes their evolution. The universe can't exchange anything with another system, so technically we can't really say that it evolves. This is sometimes denoted with a trivial formula Hpsi_universe=0, i.e. the Hamilton operator applied to the wave function of the universe is zero. This is intellectual nonsense because we can't even assign a wave function to the universe... one can't make an ensemble of universes (i.e. an infinite repetition of the "universe experiment"). So the way we usually understand physics (as a divide and conquer strategy) just doesn't work on "the whole".
