Title: A new perspective on black hole information
Abstract: I will describe recent work that shows that quantum gravity localizes information very differently from ordinary quantum field theories. A general principle appears to be that, in a theory of quantum gravity, a copy of all the information available on a Cauchy slice is also available near the boundary of the Cauchy slice. This is a phenomenon that is already apparent in the low-energy theory. When applied to black holes this suggests that the exterior of the black hole always retains a complete copy of the information in the interior. I will present a non-technical introduction to these ideas in this talk.
