Episode notes

I'm perfectly happy to ask what's real. I think that's what I'm very interested in doing, but otherwise, I do very much appreciate the, you know, operationalizing and simplifying like what gets us understanding. But let me ask almost the same question, but in a slightly more down to Earth way, which is more sympathetic to the philosophy just put forward. The ADSC of T correspondence posits an equivalence between a description with anti-desider kind of universe and one fewer dimensions of space time at the boundary with no gravity at all. So my question is, if that were the universe, right? If we really did live in ADSC, would we live

Stephen Hawking’s discoveries of black hole radiation, entropy, and the information-loss problem have both taught us an enormous amount about the relationship between quantum mechanics and gravity, and also left us with some knotty puzzles. One major insight is the holographic principle: the information describing a black hole can be thought of as living on the event horizon (the two-dimensional boundary of the hole), rather than distributed throughout its volume, as normal physics would lead us to expect. Raphael Bousso has made important contributions to our understanding of holography and its implications. We talk about the modern point of view of how gravity relates to quantum mechanics.

Raphael Bousso received his Ph.D. in physics from Cambridge University, where his advisor was Stephen Hawking. He is currently a professor of physics at UC Berkeley. He has made pioneering contributions to our understanding of black hole information, the holographic principle, the string theory landscape, and multiverse cosmology.
