Quantum chaos inside Black Holes

TL;DR

This paper proposes a new model called 'frizzyballs' that reinterprets semiclassical black holes as ensembles of horizonless singularities, offering insights into information propagation and paradoxes in quantum gravity.

Contribution

It introduces the concept of frizzyballs as an effective geometry composed of naked singularities, providing a novel perspective on black hole structure and information dynamics.

Findings

Infalling information propagates chaotically within frizzyballs.

Frizzyballs can be rigorously defined via Euclidean path integrals.

Implications for resolving black hole information paradoxes.

Abstract

We show how semiclassical black holes can be reinterpreted as an effective geometry, composed of a large ensamble of horizonless naked singularities (eventually smoothed at the Planck scale). We call this new items {\it frizzyballs}, which can be rigorously defined by euclidean path integral approach. This has interesting implications regarding information paradoxes. We demonstrate that infalling information will chaotically propagate inside this system before going to the full quantum gravity regime (Planck scale).
