Seeking connections between wormholes, gravastars, and black holes via noncommutative geometry

TL;DR

This paper explores how noncommutative geometry can make black holes, wormholes, and gravastars observationally indistinguishable, and discusses their potential connections and implications for dark energy modeling.

Contribution

It introduces a framework linking black holes, wormholes, and gravastars through noncommutative geometry, proposing new ways to understand their observational similarities and theoretical constructions.

Findings

Black holes may appear as traversable wormholes due to noncommutative effects.

Wormholes could be indistinguishable from gravastars in this framework.

Noncommutative geometry can model dark energy phenomena.

Abstract

Noncommutative geometry, an offshoot of string theory, replaces point-like objects by smeared objects. The resulting uncertainty may cause a black hole to be observationally indistinguishable from a traversable wormhole, while the latter, in turn, may become observationally indistinguishable from a gravastar. The same noncommutative-geometry background allows the theoretical construction of thin-shell wormholes from gravastars and may even serve as a model for dark energy.
