Comment on "Constraints on Low-Energy Effective Theories from Weak Cosmic Censorship"

TL;DR

This paper critiques a recent claim that the weak cosmic censorship conjecture constrains effective field theories, identifying and correcting a key error that invalidates the original conclusion.

Contribution

The authors identify and correct a key error in previous work, showing that the weak cosmic censorship conjecture does not constrain high-order effective gravitational theories as previously claimed.

Findings

The original approximate black hole solution contained a significant error.

Correcting the error invalidates the previous conclusion about WCCC constraints.

The weak cosmic censorship conjecture does not impose constraints on high-order effective theories based on this analysis.

Abstract

Recently, it was argued in [Phys. Rev. Lett. {\bf126}, 031102 (2021)] that the WCCC can serve as a constraint to high-order effective field theories. However, we find there exists a key error in their approximate black hole solution. After correcting it, their calculation cannot show the ability of WCCC to constrain the gravitational theories.
