Traversable wormholes sustained by an extra spatial dimension

TL;DR

This paper investigates how an extra spatial dimension can support traversable wormholes, allowing the wormhole throat to be threaded with ordinary matter and explaining energy condition violations through higher-dimensional effects.

Contribution

It introduces a model demonstrating that extra dimensions can sustain traversable wormholes with ordinary matter, providing a new perspective on energy condition violations.

Findings

Wormhole throat can be threaded with ordinary matter under certain conditions.

Null energy condition violation can be attributed to the extra dimension.

Model supports the feasibility of traversable wormholes in higher-dimensional theories.

Abstract

This paper explores the effect of an extra spatial dimension on a Morris-Thorne wormhole. After proposing a suitable model, it is shown that under certain conditions, the throat of the wormhole can be threaded with ordinary matter, while the unavoidable violation of the null energy condition can be attributed to the existence of the extra dimension.
