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.

Very interesting lecture, wonder how much progress has been made since this lecture

What a boss. I wish I had taken his lectures when I was at Stanford.

Loved this video!

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?
