Title: Replica Wormholes and the Information Paradox

Abstract:
Black hole evaporation seems to create too much entropy. This violates unitarity and is the essence of Hawking's black hole information paradox. I will give a broad overview of recent progress on this problem involving spacetime wormholes in the gravitational path integral. This leads to a new calculation of the entropy compatible with unitarity, and has general consequences for how we interpret black holes in quantum gravity.
