  While wormholes may be just as good a prediction of Einstein's theory as
black holes, they are subject to severe restrictions from quantum field theory.
In particular, a wormhole can only be held open by violating the null energy
condition, calling for the existence of "exotic matter," a condition that many
researchers consider completely unphysical, enough to rule out macroscopic
traversable wormholes. An equally serious problem is the enormous radial
tension at the throat of a typical Morris-Thorne wormhole unless the wormhole
has an extremely large throat size. It has been proposed that noncommutative
geometry, an offshoot of string theory, may be the proper tool for addressing
these issues. The purpose of this paper is two-fold: (1) to refine previous
arguments to make a stronger and more detailed case for this proposal and (2)
to obtain a complete wormhole solution from the given conditions.
