Eliminating black holes singularity in Brane world Cosmology

TL;DR

This paper explores a 5D brane world model where black hole singularities are eliminated by emergent universes, redefining particle dynamics to remove classical singularities.

Contribution

It introduces a novel 5D brane setup that results in non-singular black hole centers by analyzing particle motion in the emergent universes.

Findings

Singularity at black hole centers is removed in the model.

Particles follow modified equations of motion in the new universes.

The approach offers a classical resolution to black hole singularities.

Abstract

In recent works, a construction was proposed resulting emergent universes inside black holes. This result can be obtained from a 4D black hole embedded in a 5D space time with the fifth dimension compactified on a circle [0, 2] (0 and 2 are identified) such that the two branes are at 0 and 1. In the present work, we study this setup by deriving particles equations of motion in the new universes, based on redefining energy and angular momentum. This leads to disappearance of the singularity in centres of black holes in classical General Relativity.
