  Einstein-Dirac-Maxwell wormholes are asymptotically flat static wormhole
solutions in general relativity that do not make use of exotic matter. The
asymmetric static solutions are smooth, are regular everywhere, and violate the
null energy condition, which suggests that they are traversable. To determine
if in fact they are traversable, we numerically evolve the static solutions
forward in time. In all cases considered, our simulations indicate that black
holes form that are connected by the wormhole. Although there exist null
geodesics that travel through the wormhole, we find that they are trapped
inside a black hole and are unable to travel arbitrarily far away. We conclude
that Einstein-Dirac-Maxwell wormholes are not traversable.
