Non-Singular Constant Curvature Two-Dimensional Black Hole

TL;DR

This paper demonstrates that the two-dimensional Teitelboim-Jackiw black hole solution has constant curvature and no spacetime singularities, featuring an infinite chain of universes connected by wormholes.

Contribution

It reveals a novel non-singular, constant curvature black hole solution in two-dimensional gravity with a unique multiverse structure.

Findings

Black hole solution with constant curvature

Absence of spacetime singularities

Infinite chain of universes connected by wormholes

Abstract

We show that the two-dimensional theory of Teitelboim and Jackiw has a black hole solution, with two surprising properties: first, it has constant curvature, and second, is free of spacetime singularities. The maximally extended spacetime consists of an infinite chain of universes connected by timelike wormholes.
