The present article lies at the interface between
gravity, a highly nonlinear phenomenon, and quantum field theory.
The nonlinear field equations of Einstein permit the theoretical
existence of classical wormholes. One of the fundamental questions
relates to the practical viability of such wormholes. One way to
answer this question is to assess if the total *volume* of
exotic matter needed to maintain the wormhole is finite. Using
this value as the lower bound, we propose a modified semiclassical
volume Averaged Null Energy Condition (ANEC) constraint as a
method of discarding many solutions as being possible
self-consistent wormhole solutions of semiclassical gravity. The
proposed constraint is consistent with known results. It turns
out that a class of Morris-Thorne wormholes can be ruled out on
the basis of this constraint.
