Leonel Bixano, I. A. Sarmiento-Alvarado, Tonatiuh Matos

TL;DR
This paper reviews a novel form of cosmic censorship involving wormholes that causally disconnect singularities from the universe, supported by exact solutions to Einstein--Maxwell--Dilaton equations.
Contribution
It introduces the concept of Wormhole Cosmic Censorship and provides exact solutions demonstrating singularities hidden within wormholes.
Findings
Ring singularities are causally disconnected from the universe.
Exact solutions to Einstein--Maxwell--Dilaton equations are presented.
Wormholes can hide singularities from external observation.
Abstract
Spacetime singularities, in the sense that curvature invariants are infinite at some point or region, are thought to be impossible to observe, and must be hidden within an event horizon. This conjecture is called Cosmic Censorship (CC), and was formulated by Penrose. Here we review another type of CC where spacetime singularities are causally disconnected from the universe, because the throat of a wormhole ``sucks in'' the geodesics and prevents them from making contact with the singularity. In this work, we present a series of exact solutions to the Einstein--Maxwell--Dilaton equations that feature a ring singularity; that is, the curvature invariants are singular in this ring, but the ring is causally disconnected from the universe so that no geodesics can touch it. This extension of CC is called Wormhole Cosmic Censorship.
