Are naked singularites forbidden by the second law of thermodynamics?

TL;DR

This paper proposes that the second law of thermodynamics, combined with the Weyl curvature hypothesis, may prevent the formation of naked singularities in classical general relativity, suggesting a fundamental physical principle at play.

Contribution

It introduces a novel argument that the second law of thermodynamics could prohibit naked singularities, linking thermodynamics with gravitational singularity censorship.

Findings

Naked singularities are not observed in nature.

The second law of thermodynamics may serve as a physical principle forbidding naked singularities.

Abstract

By now, many examples of naked singularities in classical general relativity are known. It may however be that a physical principle over and above the general theory prevents the occurrence of such singularities in nature. Assuming the validity of the Weyl curvature hypothesis, we propose that naked singularities are forbidden by the second law of thermodynamics.
