Comment on Self-Consistent Model of Black Hole Formation and Evaporation

TL;DR

This paper discusses the implications of a self-consistent model of black hole formation and evaporation, particularly addressing the information loss paradox and firewall problem, based on prior work involving collapsing null dust shells.

Contribution

It provides insights into the consequences of Kawai et al's model for black hole information paradox and firewall issues, clarifying their potential resolutions.

Findings

Addresses the information loss paradox

Analyzes firewall problem implications

Highlights the role of back reaction in black hole models

Abstract

In an earlier work, Kawai et al proposed a model of black-hole formation and evaporation, in which the geometry of a collapsing shell of null dust is studied, including consistently the back reaction of its Hawking radiation. In this note, we illuminate the implications of their work, focusing on the resolution of the information loss paradox and the problem of the firewall.
