Macroscopic wormholes in noncommutative geometry

Abstract

The purpose of this paper is to show that wormholes in non-commutative geometry can be macroscopic, based in part on an earlier study. The necessary violation of the weak energy condition is attributable to the noncommutative-geometry background rather than to the use of "exotic matter." The zero tidal forces make the wormhole suitable for humanoid travelers. Also discussed is the stability to linearized radial perturbations. © 2013 Academic Publications, Ltd.
