Charged Black Hole in Gravity's Rainbow: Violation of Weak Cosmic Censorship

TL;DR

This paper shows that gravity's rainbow can cause charged black holes to be overspun and violate the weak cosmic censorship conjecture and thermodynamics during charged particle absorption.

Contribution

It demonstrates that gravity's rainbow effects can lead to violations of cosmic censorship and thermodynamics in charged black holes, a novel insight into quantum gravity modifications.

Findings

Rainbow effect enables overspinning of black holes.

Violations of weak cosmic censorship are demonstrated.

Second law of thermodynamics is violated in this context.

Abstract

We investigate the validity of weak cosmic censorship conjecture for electrically charged black holes in the presence of gravity's rainbow under charged particle absorption. The rainbow effect is shown to play an important role when the black hole is modified by a particle carrying energy and electric charge. Remarkably, we prove that the rainbow-charged black hole can be overspun beyond the extremal condition under charged particle absorption. Further, it is demonstrated that the second law of thermodynamics and cosmic censorship conjecture are violated owing to the rainbow effect.
