The scientific reasons for trying to make traversable wormholes are briefly reviewed. Methods for making wormholes employing a Machian transient mass fluctuation are examined. Several problems one might encounter are mentioned. They, however, may just be engineering difficulties. The use of “quantum inequalities” to constrain the existence of negative mass-energy required in wormhole formation is briefly examined. It is argued that quantum inequalities do not prohibit the formation of artificial concentrations of negative mass-energy.
