Overspinning a nearly extreme black hole and the Weak Cosmic Censorship conjecture

TL;DR

This paper examines the possibility of overspinning nearly extreme black holes through quantum tunneling, suggesting that quantum effects could lead to the formation of naked singularities, challenging the Weak Cosmic Censorship conjecture.

Contribution

It demonstrates that neutral massless fermions can bypass superradiance effects, supporting the idea that quantum tunneling might violate the Weak Cosmic Censorship conjecture.

Findings

Neutral massless fermions evade superradiance effects.

Quantum tunneling could lead to naked singularities.

Supports potential violation of the Weak Cosmic Censorship conjecture.

Abstract

We revisit here the recent proposal for overspinning a nearly extreme black hole by means of a quantum tunneling process. We show that electrically neutral massless fermions evade possible back reactions effects related to superradiance, confirming the view that it would be indeed possible to form a naked singularity due to quantum effects.
