Information recovery from evaporating black holes

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 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.

Automated summary

The study reveals that the apparent horizon and region near r = 0 of an evaporating charged, rotating black hole are timelike, suggesting that natural black holes with rotation have a channel for classical or quantum information to escape to the outside while the black hole shrinks. This has implications for the information loss problem.
