No Firewalls or Information Problem for Black Holes Entangled with Large Systems

TL;DR

This paper proposes that entanglement with large, inaccessible systems can resolve the black hole information paradox and prevent firewall formation, challenging previous assumptions about black hole entanglement and information loss.

Contribution

It introduces a model where entanglement with large systems restores complementarity and avoids firewalls, offering a new perspective on black hole information preservation.

Findings

Entanglement with large systems can prevent firewalls.

Black holes can avoid the information problem under certain conditions.

Previous arguments about generic entanglement may be flawed.

Abstract

We discuss how under certain conditions the black hole information puzzle and the (related) arguments that firewalls are a typical feature of black holes can break down. We first review the arguments of AMPS favoring firewalls, focusing on entanglements in a simple toy model for a black hole and the Hawking radiation. By introducing a large and inaccessible system entangled with the black hole (representing perhaps a de Sitter stretched horizon or inaccessible part of a landscape) we show complementarity can be restored and firewalls can be avoided throughout the black hole's evolution. Under these conditions black holes do not have an "information problem". We point out flaws in some of our earlier arguments that such entanglement might be generically present in some cosmological scenarios, and call out certain ways our picture may still be realized.
