Comment on the black hole firewall

TL;DR

This paper discusses the black hole firewall paradox, questioning the assumption that early Hawking radiation is entangled with late radiation, which impacts the debate on black hole complementarity and the firewall hypothesis.

Contribution

It challenges a key assumption in the firewall argument, offering a different perspective on the entanglement structure of Hawking radiation.

Findings

Questions the entanglement assumption in firewall argument

Highlights implications for black hole complementarity

Suggests alternative interpretations of Hawking radiation

Abstract

Recently, it has been argued that black hole complementarity is inconsistent by showing that, for an infalling observer, it would lead to the existence of a firewall near the black hole horizon, thereby violating the equivalence principle. If true, this would necessitate to give up on at least one of the postulates of black hole complementarity. In this comment I want to address an additional assumption that went into the conclusion, that the early outgoing Hawking radiation is entangled with the late radiation.
