      HEY! The man knows comfort, and practicality. It is unnecessary and inefficient for him to wear a suit and tie for what, to stand in front of a chalkboard and talk to a bunch of college students? IMHO it would be fine if he walked into class wearing a goddamn bathrobe and shower sandals.

    In the Penrose diagram of a single black hole it seems to be insisting on the idea that a free falling observer through the event horizon will hit the singularity fastest and a constantly accelerating observer will hit the singularity after a longer amount of time passes. What I'm wondering is, is this the case still if your constantly accelerating towards the singularity, or better yet, is there no actual coordinate point to the singularity but instead a singularity dependant on time and not coordinates? Because it seems to me that in the Penrose diagram after passing into the event horizon the spatial coordinates seem meaningless, as no matter which way you accelerate you reach the singularity at the same time as long as your acceleration is consistent in all directions.
    Can someone clear this up for me?

    40:18 interesting. so you could probe the interior of black holes with quantum entanglement? but more importantly does that mean that if the observable universe was the interior of a black hole, then we could probe the exterior.

    When I was younger and read about entanglement and particle "spins", I used to think a similar thought - that there was a copy of something and what happened to one, happened to the other. As I got older, the more I suspected that it was just a strong relationship/correlation that they shared and could be measured. It was really cool to hear Susskind explain it that way. Imagine you and a friend split 100 dollars. Now if I asked how much one of you got, regardless of how you split it up, I would know the other's amount immediately. Both amounts were different but give the same information, they are correlated and in a sense, entangled. Similarly, this only works with two parts and if you add a third part to this money example, you can't get the information you need.

    • @baktru
      @baktru 2 роки тому

      Except now you added hidden information. The universe already knows how many dollars of the 100 each of them has. The baffling thing is that the two friends can each travel to a different city first without the information about which has how much money even existing. Then you check how many dollars the one guy has (which up to this point is B-100 dollars) and you see 40 dollars for A so you know B has 60.

    @gliese909 10 років тому +3

    Agreed! The big bang just may have been a supernova explosion. I also think that in terms of black holes and quantum physics, size does not matter at all. Remember the movie "Men in black" where Orion the cat was wearing a small jewel containing a galaxy.

He looked exactly like John Lennon with more hair, and he was also good friends with the Japanese royal family. He dressed up when they came to visit; in tie-dye.
