Holographic Space-Time Does Not Predict Firewalls

TL;DR

This paper uses Holographic Space-time formalism to argue that black holes do not develop firewalls, showing no dramatic change in particle physics until near the Schwarzschild radius, contrasting prior claims.

Contribution

It demonstrates that HST does not predict firewalls, challenging previous models that suggested early encounter with highly excited states inside black holes.

Findings

No early firewall formation in HST

Particle physics remains stable until near the horizon

Contrasts with earlier quantum gravity models

Abstract

We use the formalism of Holographic Space-time (HST) to investigate the claim of [1] that old black holes contain a firewall, i.e. an in-falling observer encounters highly excited states at a time much shorter than the light crossing time of the Schwarzschild radius. This conclusion is much less dramatic in HST than in the hypothetical models of quantum gravity used in [1]. In HST there is no dramatic change in particle physics inside the horizon until a time of order the Schwarzschild radius.
