SUMMARY:Replica wormholes\, the black hole information paradox\, and c
 osmology\, Theory Seminar (High Energy/Cosmology)\, Edgar Shaghoulian\
 , University of Pennsylvania
DESCRIPTION:I will introduce the black hole information paradox and br
 iefly review the role that replica wormholes play in obtaining black h
 ole evolution consistent with unitarity. I will then discuss general c
 onsistency conditions that guide the search for such nontrivial saddle
 s in the gravitational path integral\, with several examples in cosmol
 ogical spacetimes.
