Résumé |
I will describe a surprising connection between two longstanding conjectures: Cosmic
censorship and weak gravity. I will first present a class of counterexamples to (weak) cosmic
censorship in anti-de Sitter spacetime. These are solutions in which the curvature grows
without bound in a region of spacetime visible to infinity. I will then explain the weak gravity
conjecture and show that when it is satisfied, these counterexamples go away. Various
generalizations will be discussed, always with the same conclusion: the weak gravity
conjecture removes potential counterexamples to cosmic censorship. |
