Can a wormhole supported by only small amounts of exotic matter really be traversable?

open access: yes, 2004
Recent studies have shown that (a) quantum effects may be sufficient to support a wormhole throat and (b) the total amount of "exotic matter" can be made arbitrarily small. Unfortunately, using only small amounts of exotic matter may result in a wormhole
