QMAP Particles/Cosmology Seminar: Tom Hartman

Description Speaker: Tom Hartman (Cornell)
Title: Replica Wormholes and the Information Paradox
Zoom: https://zoom.us/j/186024391
Host: John Terning

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.
