In reality, wormholes are purely a scientific conjecture, a consequence of the same equations that describe black holes. Being inconveniently located at (or near) the centers of said black holes, it is of course impossible to detect them, at least with current technology. The theoretical wormhole would, thanks to relativistic effects, close before anyone could get through it, no matter how fast they were traveling. One way to get around this could be to try to get through a wormhole inside a rotating black hole; but even then, you'd have to somehow survive being pummeled by a ridiculous amount of radiation, and somehow not create any disturbance and collapse the wormhole altogether. Actually stabilizing the wormhole would theoretically require "exotic matter"... which would have, among other never-encountered qualities, negative mass... Needless to say, wormholes have remained a curiosity in the field of physics, and are certainly not being considered for practical travel anytime soon.

It's been [[https://arxiv.org/abs/gr-qc/9309017 theorised]] that tiny wormholes may constantly appear and disappear in [[https://en.wikipedia.org/wiki/Quantum_foam quantum foam]].

The theory around wormholes gives them various properties not generally shown in fiction. [[http://www.webfilesuci.org/WormholeFAQ.html To begin with]], a wormhole would consist of two (probably spherical) mouths connected by a throat. Another property is that sending something through a wormhole would [[https://www.npl.washington.edu/av/altvw162.html affect the wormhole as well]], a phenomenon known as back-reaction. For example, if a mass were to be sent from one mouth of a wormhole to the other, the entry mouth would gain mass and the exit mouth would lose mass. This kind of EquivalentExchange means that wormhole travel would require moving equal masses in both directions, to keep the mouth masses balanced. Another property is that wormhole mouths could be moved around. A civilisation capable of using wormholes at all wouldn't need spaceships, it could shoot one mouth of a wormhole to some distant planet and keep the other mouth at home, and then it would be possible to basically walk from one planet to another.

Fiction, of course, is different. Wormholes are often used as a potential way to get past that bothersome "[[{{FTL}} can't accelerate past the speed of light]]" rule, using the wormholes as nodes in an interstellar PortalNetwork. In fiction, wormholes take on all sorts of forms, including confusing them with black holes, which are a naturally-occurring scientific phenomena in which all energy and matter are [[GravitySucks attracted to it]] (also known as having a lot of gravity); nothing can escape the event horizon of a black hole (though if FTL ''were'' possible, the event horizon -- being based on lightspeed as an absolute limit to escape velocity -- would need to be redefined), let alone the singularity at the centre (as things would need to, were they to act as most theories of wormholes state). Sometimes they can be opened at will, sometimes you can transmit radio waves through them for FTLRadio, sometimes they connect you to [[AlternateUniverse parallel universes]], sometimes they are used for TimeTravel, and so on.
