Thermodynamics of gravity favours Weak Censorship Conjecture

TL;DR

This paper shows that gravitational thermodynamics naturally favors scenarios where the weak cosmic censorship conjecture holds, indicating that gravity's thermodynamic properties support the preservation of spacetime predictability.

Contribution

It demonstrates that gravitational entropy calculations favor the weak censorship conjecture over the strong one during dust collapse, without additional matter constraints.

Findings

Gravitational entropy prefers weak censorship scenarios.

Weak cosmic censorship is supported by thermodynamic considerations.

Strong censorship violations are thermodynamically disfavored.

Abstract

We use the formulation of thermodynamics of gravity as proposed by Clifton, Ellis and Tavakol on the gravitational collapse of dustlike matter, that violates the strong or weak cosmic censorship conjecture depending on the initial data. We transparently demonstrate that the gravitational entropy prefers the scenario where the stronger version is violated but the weak censorship conjecture is satisfied. This is a novel result, showing the weak cosmic censorship and hence the future asymptotically simple structure of spacetime, is being validated by the nature of gravity, without imposing any extra constraint on the form of matter.
