218 | Raphael Bousso on Black Holes and the Holographic Universe

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.

It's too easy to take laws of nature for granted. Sure, gravity is pulling us toward Earth today; but how do we know it won't be pushing us away tomorrow? We extrapolate from past experience to future...
