Many problems exist with the possible usage of wormholes to travel. For one thing, theoretical wormholes are only big enough to allow microscopic particles to pass through. Also, naturally occurring wormholes would exist for only a fraction of a second. Finally the wormhole would not be stable enough to let anything pass through it. If a particle attempted to pass through it, the waves of gravity caused by its passage will destroy the fragile wormhole. If all these problems exist, why are wormholes even considered as a possible means of transport? There are possible solutions to the problems associated with wormholes.
