Wormholes and the information paradox
Black hole evaporation seems to create too much entropy, violating unitarity. This is the essence of Hawking's black hole information paradox. I will describe recent progress on this problem involving spacetime wormholes in the gravitational path integral. This leads to a new result for the entropy of Hawking radiation that is compatible with unitarity, and has general consequences for how we interpret black holes in quantum gravity. It also leaves many open questions that I will highlight in this talk.
