Hyper-Entropic Gravitational Fireballs (Grireballs) with Firewalls

TL;DR

This paper explores the theoretical concept of hyper-entropic gravitational fireballs, or grireballs, which are hypothetical objects with more entropy than black holes of the same mass, discussing their properties under various assumptions.

Contribution

It introduces and analyzes the properties of grireballs, extending the firewall idea to hypothetical hyper-entropic objects with potential implications for quantum gravity.

Findings

Properties depend on how radius and entropy scale with mass.

Assuming radius and entropy as functions of mass or as independent parameters.

Discussion of theoretical consistency and implications for quantum gravity.

Abstract

Recently there has been much discussion as to whether old black holes have firewalls at their surfaces that would destroy infalling observers. Though I suspect that a proper handling of nonlocality in quantum gravity may show that firewalls do not exist, it is interesting to consider an extension of the firewall idea to what seems to be the logically possible concept of hyper-entropic gravitational hot objects (gravitational fireballs or grireballs for short) that have more entropy than ordinary black holes of the same mass. Here some properties of such grireballs are discussed under various assumptions, such as assuming that their radii and entropies both go as powers of their masses as the one independent parameter, or assuming that their radii depend on both their masses and their entropies as two independent parameters.
