Information recovery from evaporating black holes

TL;DR

This paper demonstrates that the regions near evaporating charged, rotating black holes are timelike, allowing information to escape, which has significant implications for the black hole information loss paradox.

Contribution

It reveals that the apparent horizon and near-origin region of evaporating rotating black holes are timelike, providing a potential pathway for information escape.

Findings

Apparent horizon and near r=0 are timelike in evaporating black holes.

Rotation enables a channel for information to escape.

Implications for resolving the black hole information loss problem.

Abstract

We show that the apparent horizon and the region near $r=0$ of an evaporating charged, rotating black hole are timelike. It then follows that for black holes in nature, which invariably have some rotation, have a channel, via which classical or quantum information can escape to the outside, while the black hole shrinks in size. We discuss implications for the information loss problem.
