Excluding Black Hole Firewalls with Extreme Cosmic Censorship

TL;DR

This paper proposes Extreme Cosmic Censorship to exclude singular states, resolving the black hole firewall paradox while maintaining information preservation in Hawking radiation.

Contribution

Introducing Extreme Cosmic Censorship as a principle to exclude singular states, preventing firewalls and preserving information in black hole evaporation.

Findings

Excludes singular states from black hole models.

Prevents the formation of firewalls.

Supports information preservation in Hawking radiation.

Abstract

The AMPS argument for black hole firewalls seems to arise not only from the assumption of local effective field theory outside the stretched horizon but also from an overcounting of internal black hole states that include states that are singular in the past. Here I propose to exclude such singular states by Extreme Cosmic Censorship (the conjectured principle that the universe is entirely nonsingular, except for transient singularities inside black and/or white holes). I argue that the remaining set of nonsingular realistic states do not have firewalls but yet preserve information in Hawking radiation from black holes that form from nonsingular initial states.
