Model of black hole evolution

TL;DR

This paper proposes a novel model for black hole evolution based on boundary conditions at the apparent horizon, suggesting minimal energy radiation and information retention within the black hole geometry.

Contribution

It introduces an unconventional black hole evolution scenario replacing the interior with a boundary, emphasizing minimal radiation and information preservation.

Findings

Very small fraction of energy is radiated out.

Most quantum information remains in the final black hole geometry.

Black hole evolution can be modeled via boundary conditions at the apparent horizon.

Abstract

From the postulate that a black hole can be replaced by a boundary on the apparent horizon with suitable boundary conditions, an unconventional scenario for the evolution emerges. Only an insignificant fraction of energy of order $(mG)^{-1}$ is radiated out. The outgoing wave carries a very small part of the quantum mechanical information of the collapsed body, the bulk of the information remaining in the final stable black hole geometry.
