Quantum gravity, chaos, statistical physics and wormholes — •Jan de Boer — University of Amsterdam

The information paradox for black holes has been an important source of inspiration for research in quantum gravity, as the paradox implies that low-energy effective field theories that include gravity must break down in an interesting and unexpected way. Recent work has managed to clarify the physics behind the paradox considerably and uncovered fascinating relations between gravity and wormholes on the one hand and chaos, quantum information and statistical physics on the other hand. One lesson seems to be that low-energy observers in gravitational theories do in fact have some access to high-energy information, but only to statistical and not to microscopic information. In this picture wormhole solutions are a direct manifestation of this statistical high-energy information.

In this talk I will try to give an informal summary of some of these developments, trying to emphasize the general lessons rather than the technical details.
