Wormholes are a mainstay of science fiction, permitting fictional trips across vast distances in reasonable amounts of time, as well as time travel. Despite some theoretical scientific basis for their actual existence, useful wormholes remain more a part of science fiction than of science fact.

Here are some resources to learn more about wormholes:
