  Noncommutative geometry, an offshoot of string theory, replaces point-like
particles by smeared objects. These local effects have led to wormhole
solutions in a semiclassical setting, but it has also been claimed that the
noncommutative effects can be implemented by modifying only the energy momentum
tensor in the Einstein field equations, while leaving the Einstein tensor
unchanged. The implication is that noncommutative-geometry wormholes could be
macroscopic. The purpose of this paper is to confirm this conclusion in a
simpler and more concrete manner by showing that the throat radius can indeed
be macroscopic. This result can be readily explained by considering the
noncommutative-geometry background to be a fundamental property and the
macroscopic wormhole spacetime to be emergent.
