DESCRIPTION:Euclidean wormholes have played an important role in recent pr
 ogress on 2D gravity and on black hole information in higher dimensions. H
 owever\, these spacetimes can also lead to puzzling results that seem to d
 isagree with quantum mechanics and the AdS/CFT correspondence\, which has 
 led to the suggestion that wormholes arise from coarse-graining over UV de
 grees of freedom. I will explain the puzzle and show that Euclidean wormho
 les and other higher topology spacetimes in 3D gravity can be interpreted 
 as averaged solutions of the 2D conformal bootstrap equations.
