Observables of super-extremal black holes: challenging Cosmic Censorship to comprehend the Cosmological Constant

TL;DR

This paper explores the possibility that super-extremal charged black holes could be sources of dark energy, challenging the Cosmic Censorship conjecture and offering a new perspective on the Cosmological Constant through observational signatures.

Contribution

It proposes a novel hypothesis linking super-extremal black holes to dark energy and outlines observational strategies to identify such objects.

Findings

Super-extremal black holes may exist with weak observational signatures.

Sky surveys could detect candidates that challenge Cosmic Censorship.

These objects might explain the physical origin of the Cosmological Constant.

Abstract

Einstein's Field Equations have proven applicable across many scales, from black holes to cosmology. Even the mysterious Cosmological Constant found a physical interpretation in the so-called ``dark energy'' causing the accelerated cosmic expansion as inferred from multiple observables. Yet, we still lack a material source for this dark fluid. Probing the local universe to find it yields complementary information to the one from the cosmic microwave background. Could dark energy be sourced by super-extremal charged black holes? Contrary to intuition, such objects could exist with only weak observational signatures. The latter are introduced here to outline how sky surveys can identify individual candidates which challenge Cosmic Censorship on the one hand but may explain the physical origin of the Cosmological Constant on the other.
