Testing the Weak Gravity -- Cosmic Censorship Connection
Toby Crisford, Gary T. Horowitz, Jorge E. Santos

TL;DR
This paper explores the link between the weak gravity conjecture and cosmic censorship, showing that if the conjecture holds, violations of cosmic censorship are prevented, with the required charge matching the conjecture's predictions.
Contribution
It provides evidence that the weak gravity conjecture ensures cosmic censorship by preventing certain violations in Einstein-Maxwell-$\\Lambda$ theory.
Findings
Presence of charged particles with sufficient charge prevents cosmic censorship violations.
The minimum charge needed aligns with the weak gravity conjecture's proposal.
Supports the idea that the weak gravity conjecture underpins cosmic censorship.
Abstract
A surprising connection between the weak gravity conjecture and cosmic censorship has recently been proposed. In particular, it was argued that a promising class of counterexamples to cosmic censorship in four-dimensional Einstein-Maxwell- theory would be removed if charged particles (with sufficient charge) were present. We test this idea and find that indeed if the weak gravity conjecture is true, one cannot violate cosmic censorship this way. Remarkably, the minimum value of charge required to preserve cosmic censorship appears to agree precisely with that proposed by the weak gravity conjecture.
