We should ALL strive to achieve something in our own lives that at least RESEMBLES what is seen here.
I love your enthusiasm. And I wish I shared it . . . in my opinion, this style of presentation falls way short of earning your level of admiration--though I totally agree he knows his field. If you have time, try a "Cool Worlds" video from David Kipping, of Columbia's astronomy dept. He is my dream professor. I'd very much respect your impression. This is one of his best videos--

man, what I would give to sit around a table eating lunch and discussing black holes with other people who are interested. thankfully this was recorded
I have watched a bunch of Susskind lectures. I thought I had gotten to the end of his points with the holographic /black hole angle. Now he brings in an entirely new physics. Just amazing. And very easy to listen to, in the Feynman model.
I enjoyed listening to this while doing other stuff. It was similar to my college experience in so much as my brain was elsewhere while smart people talked.

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.
the guys eating in the front, love it XD this professor is amazing and I would highly recommend him if you want to learn anything to do with physics or astrophysics
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.
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.
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.
ILiveuDertHeBrige In academics, clothes, hair, even your socks don't matter. Our biology department head wore tie-dye all the time. 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.
