Bouncing Geodesics

Understanding the interior of black holes remains an important fundamental challenge. This talk reviews bouncing geodesics and their associated bouncing singularities as sharp geometric diagnostics of the black hole interior. In AdS/CFT, these geometric bounces correspond to distinct structures in the dual operator product expansion (OPE) and boundary correlation functions. Beyond holography, bouncing singularities may be used to probe black hole interiors in (sort-of) realistic experiments.
