Toward a Traversable Wormhole

TL;DR

This paper discusses the theoretical possibility of traversable wormholes that could potentially bypass the light speed barrier, focusing on a specific class with wide throats supported by matter satisfying certain energy conditions.

Contribution

It introduces a class of static, traversable wormholes with wide throats supported by matter composed of components satisfying the Weak energy condition and vacuum fluctuations.

Findings

Wormholes of this class are static and traversable.

Matter supporting these wormholes includes vacuum fluctuations of various fields.

The matter components satisfy the Weak energy condition in part.

Abstract

In this talk I discuss pertinence of the wormholes to the problem of circumventing the light speed barrier and present a specific class of wormholes. The wormholes of this class are static and have arbitrarily wide throats, which makes them traversable. The matter necessary for these spacetimes to be solutions of the Einstein equations is shown to consist of two components, one of which satisfies the Weak energy condition and the other is produced by vacuum fluctuations of neutrino, electromagnetic (in dimensional regularization), and/or massless scalar (conformally coupled) fields.
