Replica wormholes, the black hole information paradox, and cosmology
Time: 2:00 pm
Place: For zoom link, sign up at:
Speaker: Edgar Shaghoulian, University of Pennsylvania
Abstract: I will introduce the black hole information paradox and briefly review the role that replica wormholes play in obtaining black hole evolution consistent with unitarity. I will then discuss general consistency conditions that guide the search for such nontrivial saddles in the gravitational path integral, with several examples in cosmological spacetimes.
Host: Lars Aalsma
