Maximal acceleration and black hole evaporation

TL;DR

This paper explores how theories with a maximal proper acceleration affect black hole evaporation, leading to remnants and bounds on force, challenging traditional views of black hole complete evaporation.

Contribution

It introduces the concept that maximal acceleration theories prevent complete black hole evaporation and establish force bounds based on black hole and acceleration duality.

Findings

Black holes leave remnants due to maximal acceleration effects

Remnant mass inversely related to maximal acceleration

Existence of an upper bound on force exerted on test particles

Abstract

We discuss how in certain theories of spacetime admitting a maximal proper acceleration Hawking radiation does not completely evaporate the black hole. The black hole remnant's mass depends on the inverse of the maximal acceleration. Furthermore, as a consequence of a duality between the minimum mass that a Schwarzschild black hole can have in such spacetimes and the maximal acceleration, we show that in certain theories with a maximal acceleration there must be an upper uniform bounds on the value of the force that can be exerted on test particles.
