  • Black holes warp space and time, squeeze matter to a vanishing point, and trap light so that it cannot escape. Black holes, with masses millions or billions times that of our sun, sit at the center of galaxies. How can black holes perform such stupendous tricks, and what can we learn from them?

      I dunno. His two interjections kind of bothered me because I wanted to hear how Susskind was going to describe them. For example when he blurted out, "the point of no return", I didn't think that is what Susskind was describing--even though it's true of black holes and Susskind went with it. What I thought he was describing was "the point where information is no longer transmissible". We all know there is a point where gravity in inescapable, but this didn't seem to be the crux of his analogy.

      @@soumyojitpal3399 You can read elsewhere in this thread (immediately below for me...but that is probably just my view).
      Even in this talk he gets it wrong.
      A thing stays visible at the event horizon forever? Really lets look at that.
      OK So the event horizon according to Susskind is because the object is being pulled in faster than C. And that light carries momentum and will never reach you. So light is completely a particle then! But no! It is not. Light is emitted by mass by vibrating what you call the fabric of space. Just like a jet in the sky. Do we suddenly not hear supersonic jets? No...we still hear them. Even though they are going way faster than sound...because the media carries the signal. The signal isn't particles shooting out of the jet to our ears. The sound proves this.
      So the ONLY other thing that could be happening is that the light is being pulled either directly or the media itself was being pulled. If it were the media (fabric of space) and we believe in an expanding universe, then you would at a very high speed see things being sucked into black holes.
      But Susskind and all the Big bangers (Similar to flat-earthers) do not realize how the universe works. The reason black holes are black is because of a upward shift in frequency of light far beyond gamma rays. This can happen because time-space (ether field) is much denser near a black hole because it creates ether. When that super high frequency light travels to less ether dense space the signal can no longer be carried. This loss of signal makes the black hole appear black.
      Supporting evidence.
      Matter getting sucked into a black hole and emits a gamma burst. It does this as it enters more ether dense space until it too is clocked too high and signal is lost.
      Pulls can not exist. So how else does a black hole become black. My theory is THE only game in town that fits.
      If the black holes are sucking in space then this should counter the expansion of space and we should be shrinking because this would be an immense power.
      Background radiation is from something described as a "blackhole universe". Not quite right except that black holes and this frequency mismatch are the reason.

    Splendid interview! It's so so kind of Dr. Susskind to illuminate on this luminous topic that light and other objects with "information" embedded within of not being able to escape the stranglehold of the black holes. Yet they expand our 'horizons' of understanding the principles of contemporary physics and even help amalgamate the old with the new.
    Information isn't lost. In fact, nothing is ever lost. From the absolute (say the absolute zero Kelvin) arise the "quantum jitters", like Shakti (Nature) arising out of Nothing (Shiva)! Be it the Big Bang or the Big crunch, information will be ever etched in the fabric of the DNA of the Cosmic Consciousness, like the Akashic records (Boltzmann's brain).
    Amalgamation and interchangeability is nothing new. The wave and particle properties of light and even macrocosmic objects can be boiled down to the quantum properties of wave function and its collapse thereof. Advaita (non-dualism) vedanta had long proposed the idea since the ancient times by the great Indian sages. Erwin Schrodinger, Werner Heisenberg, Albert Einstein, Aldous Huxley had experinced it ituitively and dwelled on it.
    We are not just particles, merely confined to some location in space, rather we need to think of us in terms of waves spread out over the whole Universe. Professor Sean Carroll had once said in a lecture that physicists won't tell you this fact that we are waves in reality and not just particles.
    We ever live. We don't die, ever!
    "There's got to be
    Just more to it than this
    Or tell me, why do we exist?
    I'd like to think that when I die
    I'd get a chance, another time
    And to return and live again
    Reincarnate, play the game
    Again and again and again and again" .... Iron Maiden, Infinite dreams

    I didn’t get the right physics break down of what I was looking for lol, but I’m glad about what I found. It shows how much we think we know about black holes but still so far from ever actually experimenting and learning all of its true properties. If we knew everything we desperately want to know to know about the event horizon we could probably learn how to use that area to manipulate the singularity and use the black hole as a whole to provide endless energy.

      @@atrocious_pr0xy I'm thinking along similar lines. The common theory is that black holes are the result of a collapsing star. That may be true. I am not familiar with the physics of that theory.
      But I am thinking that black holes create the galaxies that they are at the center of. It is now known that black holes eject a stream of energy and matter at their "poles". This would create an oblong galaxy. As the black hole rotated over time the oblong galaxy would become a spiral galaxy. This fits the observations of the Hubble telescopes pictures of the early universe where oblong galaxies outnumber the spiral ones. But billions of years later spiral galaxies are in the majority.

      For the model, just start with a bathtub with a drain, but imagine a round bathtub with a big drain in the center. If you put a rubber ducky in the bathtub away from the center, it hardly notices the movement of the water towards the drain. But if a rubber ducky floats near the center, the rushing water will pull it down the drain.
      Now just imagine a bigger bathtub, and then an even bigger bathtub... An "infinite" lake just means the bathtub is so big that most rubber duckies will never encounter the drain, or even notice it, because they're so far away from it. But the drain is there, and every once in a while, an unlucky rubber ducky will unhappily float too close and get swallowed.
