[[caption-width-right:320:A [[GeniusBonus Lorentzian wormhole topology held open by exotic matter with negative energy density]]. Or something.]]

In reality, wormholes are purely a scientific conjecture, a consequence of the same equations that describe black holes. There's no way that we can conceive of to get to one or use it for anything. In fiction, however, wormholes are a SwirlyEnergyThingy that can be used as a convenient means of travel from one place to another.

The most common use is for FTLTravel. By extension, if they show up often enough and consistently enough, they can become nodes in an interstellar PortalNetwork. They can also enable TimeTravel, provide a mechanism for FTLRadio, act as doorways to {{Alternate Universe}}s, or any/all of the above. No matter what {{Technobabble}} is thrown around, rarely will any two authors treat them in precisely the same manner, which is why Our Wormholes Are Different.

* Planet Remina from ''Manga/HellstarRemina'' came from AnotherDimension through a wormhole. And considering [[EldritchAbomination what the planet is]]...
* In ''Anime/SpaceDandy'', wormholes are strange distortions in space that lead out of the existing universe. It's also mentioned that the primary difference between a wormhole and a black hole is that a wormhole has an ''exit''.

[[/folder]]

[[folder:Film]]

* ''DonnieDarko'' involves one that [[spoiler: loops through time]], [[MindScrew maybe possibly]].
* The Bifröst bridge in ''Film/{{Thor}}'' is actually a traversable Einstein-Rosen Bridge (read: wormhole) appearing as a beam of light shooting to and from the sky. The myth of it being a rainbow bridge is due to the fact that it causes atmospheric disturbances as it opens up on Earth. It also comes with [[VisualEffectsOfAwesome a neat light show]].
** Apparently, if you keep it open longer than a few seconds, it can act as a WaveMotionGun and destroy an entire planet... Which makes [[JustifiedTrope a lot more sense]] when one considers the ludicrous energies required to make on of these things work in RealLife.
* The portal created by the Tesseract/Cosmic Cube in ''Film/{{The Avengers}}'' is a bit more conventional than the above, but no less spectacular: a circular doorway in the sky to wherever it is that the Chitauri come from, spewing out AliensAndMonsters to attack [[BigApplesauce New York]].
* The [[StarfishAliens Mi-Go]] portal from Yuggoth (Pluto) to Earth in the 2011 [[AdaptationExpansion adaptation]] of ''[[LovecraftOnFilm The Whisperer In Darkness]]'' seems to be mystical in nature, rather than technological. An elaborate ritual is required to open it, along with, you guessed it, HumanSacrifice. It is ''critical'' that a shaman or priest from Earth passes through first, before it can be used, lest it collapses. Oh, and it was probably left behind by [[EldritchAbomination Shub-Niggurath]].
* In ''Film/{{Contact}}'', Dr. Arroway theorizes that the the alien machine transports its subject via an Einstein-Rosen bridge.

[[/folder]]

[[folder:Literature]]
* TheMoteInGodsEye books by Larry Niven and Jerry Pournelle have this as a central plot point
* ''Literature/TheLordOfOpium'': Holoscreens are apparently these, which allow users on either side to transmit objects. Doing so is not recommended for whatever reason, and since the space between either end is freezing cold, living things will be killed if they try to go through.
* The only time a wormhole came up in the StarWarsExpandedUniverse was in ''The Phantom Affair'', an arc in the XWingSeries comics. A superweapon known as the gravitic polarizing device made the enemy ships and a portion of the asteroid belt ringing a planet simply disappear, with one of the startled pilots saying that it looked like a wormhole had opened up.
** In "The Glove of Darth Vader", a wormhole created by the exploding reactor is responsible for transporting Darth Vader's indestructible glove from the exploding wreckage of the Death Star II to the oceans of Mon Calamari.
* ''[[NightsDawn The Night's Dawn Trilogy]]'' has humans using wormhole-generating ''ZTT'' drives to cross interstellar distances. The mechanical type requires the ship to be [[http://images.wikia.com/nightsdawn/images/e/e3/Ladymac.jpg spherical]] and is bound by orbital mechanics, while the ones used by the organic [[LivingShip Voidhawks]] have no such limitations, but die after a few decades. The [[SufficientlyAdvancedAlien Kiint]] have refined the technology to the point where they use personal teleporters to jump between distant ''galaxies''.
* From the same author: In ''Literature/PandorasStar'', two hipster Californian scientists invent a wormhole generator in mid-21st century, and reveal it to the world by transporting themselves to Mars to greet the NASA astronauts [[http://psypher101.deviantart.com/art/Meeting-on-Mars-136595264 who were just landing there for the first time]]. From that day on, the very notion of space travel becomes laughable, and an interstellar empire is created with [[PortalNetwork wormholes linked by train lines]].
* Lois Mc Master Bujold's Literature/VorkosiganSaga has an interstellar community, "the Nexus," linked together by "wormholes." Rather than being stellar-scale objects of massive gravity, these are subtle flaws in spacetime that you need special equipment to detect and use. They are natural features of some star systems. Earth only has one, way out in the Oort Cloud. Lucky systems have a handful. Barrayar, the heroes' home planet, was cut off from the Nexus for centuries when their one wormhole unexpectedly closed.
* The Literature/TimeScout portals combine this with PortalToThePast.
* In ''TheWheelOfTime'', the theory behind Traveling (aportation) for male channelers is to bend space until two points are next to each other, then to drill a tiny hole. A woman warns that a female channeler (whose method is the same in effect but is quite different on the backend) attempting the same feat would fall into the gap between the two sides, which, if it's anything like other methods of hyperspace travel, is just an infinite black nothingness from which there is no escape.
* Author/StephenBaxter's ''Literature/TheLightOfOtherDays'' revolves around the discovery of a way to open up microscopic wormholes to any point in space past or present, which only allow light to pass through them. The plot revolves around two main points; the total removal of all privacy since anyone can be watched by anyone else at any time, and the ability for everyone to see what actually happened in historical events including the origins of religion. Unlike most stories in which wormholes are used for travel, the book is mainly about the societal changes caused by everyone having access to the truth of any events of any time.

[[folder: Live-Action TV ]]
* ''{{Sliders}}'' had wormholes that could only be opened at certain times, and transported people between parallel dimensions (alternate realities would be a better pair of words). A specific device was required to create said wormholes.
** In fact, each timer was unique in that each had its own cycle. Should the traveler miss his/her window, he/she would have to wait for the next one with the current timer for over 29 years - a number defined by AppliedPhlebotinum.
* ''Series/{{Farscape}}'' had a wormhole send the protagonist from our solar system into very unfamiliar space. Aliens (and thus hilarity) ensue.
** Later he turned wormholes into offensive weapons, learned how they could be used for travelling to different points in time as well as [[AlternateTimeline "unrealised" realities"]], and eventually he learned how to make a "wormhole weapon" (essentially a black hole that doubles in size every few minutes). When he revealed that last one, every villain who'd been hounding [[NeuroVault him]] for the knowledge suddenly realized [[IWarnedYou wormhole weapons were exactly as bad as he'd been telling them.]]
* ''Series/StargateSG1'' has controlled wormholes created between the titular stargates, and as the means for spacecraft to enter hyperspace.
** In the Franchise/StargateVerse, wormholes operate in ''sub''space, rather than hyperspace. Atlantis (the city) used a wormhole drive (rather than a hyperspace drive) to get from the Pegasus Galaxy to Earth (in the Milky Way) in a split second, where Hyperspace was taking weeks. OurWormholesAreDifferent indeed.
*** Atlantis used a ''hyperdrive'' to get from Pegasus to the Milky Way, and used its wormhole drive only after its hyperdrive broke down near the edge of the Milky Way. Also, in the first episode of SG-1's sixth season, a "hyperspace window" is referred to as a "wormhole," so wormholes ''are'' used to enter hyperspace.
*** Hyperspace is used by Stargates. Subspace is used by FTL travel. Various other dimensions/planes of existence are used by the Ascended, the Abydonians, and the [[Series/StargateAtlantis occasional lost half-Ascended Replicator.]]
** This franchise also has the peculiar and arbitrary "time limit" rule. It's apparently a "law of wormhole physics" that it's impossible to maintain a wormhole for more than 38 minutes (unless it's plugged into a black hole or similar massive power source, which would suggest that it's more a limitation of the stargate's power systems than anything to do with physics). In effect, though, there seem to be more exceptions than cases of this rule being played straight.
*** The first time that the 38 minute rule was exceeded was because of time dilation, not energy expenditure: on the black hole planet, 38 minutes hadn't elapsed yet. This is why the wormhole remained open. Sadly, in later episodes it just became dumbed down to "black hole/energy = wormhole can stay open longer".
** During solar flares, wormholes have a tendency to travel back in time, with the strength of the flare determining how far back/forward in time the wormhole can go. Strangely, the first time this happened, SG-1 were rematerialized without a stargate, something thought to be impossible. This forms the plotline of several episodes as well as the ''Continuum'' film.
*** Indeed, the rules for how wormholes behave under these conditions seem to be different in each and every appearance. Sometimes the wormhole "loops back" and travelers emerge from the gate they just entered, sometimes they come out of the gate they were trying to travel to, sometimes there is a visual effect associated with the disruption, sometimes not... There have been passing {{Handwave}}s about how different external conditions result in the different effects, but yeah... Those wormholes are different.
*** At first, it's not the 'solar flares', the flares are just bending the wormholes somewhere else. The implication is that someone who understood, and had full control of, a Stargate could basically connect a wormhole to any point in time or space, and the lack of time travel was a deliberate technological limitation of the gate you had to 'hack' by using solar flares to bend the wormhole. Although that raises other questions, like why did the Ancients have to build an entire separate time travel system? Later, they seemed to have forgotten this explanation, and time travel started requiring solar flares.
*** Additionally, trying to gate somewhere during a solar flare is normally not allowed using standard-issue [=DHDs=] (Ancient-build dialing devices), as their programming is designed to prevent this kind of thing. Since Earth doesn't use a DHD but has instead jury-rigged a regular computer and employs manual dialing (spinning the inner ring), the number of restrictions it follows is basically up to the programmers.
* ''Franchise/StarTrek'' has wormholes. For example, in ''Film/StarTrekTheMotionPicture,'' an imbalance in the matter-antimatter ratio in the ship's engines can create a temporary wormhole that traps the ship and other nearby objects -- like asteroids. An episode of ''Series/StarTrekTheNextGeneration'' had Ferengi trying to buy the rights to a wormhole. ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'' prominently featured a permanent wormhole as part of the premise of its show, created by SufficientlyAdvancedAliens; one episode featured a Federation scientist trying to duplicate this feat. And then there were the "micro-wormholes" used for communication between Earth and ''[[Series/StarTrekVoyager Voyager]]''.
** It's actually stated in an episode that "wormhole" is a rather generic term that covers dozens of related phenomena.
* ''TerraNova'' has a wormhole that exists in their universe 2149 and alternate timeline cretaceous period. It is still not explained if people can go back to 2149 or it is one way, but there are hints at it being the former.
* The fugitives in ''Series/{{Tracker}}'' came to Earth via a wormhole, and Cole used one in the final episode. The math apparently isn't easy to get, and he misjudged the timing, allowing him to come back to Earth in the very end. Zin apparently originated a lot of the wormhole stuff, then got laughed at by his fellow scientists for it.
* In ''Series/PowerRangersSPD'', a wormhole brought Gruumm and the Rangers back in time [[Series/PowerRangersDinoThunder 20 years.]]
* In ''Series/KamenRiderFourze'', the main hero's SuperMode, Cosmic States, can create wormholes with its weapon, the Barizun Sword.
[[/folder]]

[[folder: Tabletop Games ]]
* Porte sorcerers in ''SeventhSea'' have access to a rather bizarre version of portals. They can mark an object with their own blood, and then pull the object to them across a hand-sized portal, regardless of where it is. Later, they gain the ability to pull ''themselves'' to the object, regardless of where ''it'' is (rather handy if, for example, the object is in the pocket of a friend who's been imprisoned), and still later they can bring others with them. There are even rules for creating permanent Porte holes, though they cost an extreme version of CastFromHitPoints (as ''SeventhSea'' doesn't have HitPoints per se, creating a permanent Porte hole will permanently cost a number of Sorcerers a point of the primary stat that determines when damage kills them). Porte has other restrictions, though; the dimension that the Sorcerer (and any passengers) must cross is implied to one of a few cans holding SealedEvilInACan, either hell itself or the abode of the now-vanished AbusivePrecursors (or possibly both). It is explicitly stated that anyone, sorcerer or passenger, who opens his eyes during the trip will go mad--and that the denizens of this place will whisper sweet promises to any human making the trip, if only they'd open their eyes. All the sorceries but one in ''SeventhSea'' are also [[spoiler: weakening the boundary between the real world and hell.]] Porte, as it tears holes in reality itself, is implied to be one of the worst about these. Lastly, Porte sorcerers are easy to spot--they have red hands as a consequence of frequently blooding objects for their art. As a result, gloves have become fashionable in Montaigne.
** The consequences of Porte are dire enough that at least one canon NPC has been executed by L'Empereur (an {{Expy}} of Louis XIV) by ''having his eyelids torn off and being cast into a Porte hole.''

[[folder: Video Games ]]

* The ''[[VideoGame/{{X}} X-Universe]]'' has the Lost Technology [[PortalNetwork Jump Gates]], which are needed to get between solar systems. None of the races know how to make them [[spoiler:except the Terrans (who developed the tech on their own) and the Paranid (because they were told how by one of the {{Precursors}})]].
** [[AllThereInTheManual According to the X-Superbox Encyclopedia]], the wormholes are different due to using exotic matter to power the wormhole, and by using magnetic forces to flatten the aperture. If those factors didn't occur, it would be the exact same as RealLife's theoretical wormholes.
* ''{{Freelancer}}'' has Jump Gates that are implied to work as controlled wormholes, as well as normal, hidden wormholes that are implied to be dangerous, but perfectly safe in practice.
* The portals in ''{{Prey}}'', much like those in ''VideoGame/{{Portal}}'', show a clear view of the destination, and have zero internal length. They also have only [[AlienGeometries two dimensions and one side]], and can be used to [[MindScrew shrink]] things and create spatial anomalies.
* The portals in ''VideoGame/{{Portal}}'', though a bit more short ranged than most other examples.
** With [[CloudCuckoolander possible application]] as a [[MundaneUtility shower curtain]].
** As of VideoGame/{{Portal 2}}, they're not so short-ranged anymore; the portal gun is capable of generating wormholes at a distance of at least [[spoiler: 356400 km (from Earth to the Moon)]].
*** The portals can only be placed on certain materials [[spoiler: such as Moon rocks. They don't do good things for your health.]]. So long as they have a line to the target with no other solids in the way, the portal works.
* ''EVEOnline'': the expansion pack - Apocrypha - caused numerous wormholes to open all over New Eden. They transport ships absurd distances instantly, either to elsewhere in New Eden (distances that would take an hour to travel via stargates) or to uncharted Sleeper space (which could conceivably be in an entire other galaxy). They are only open for a limited time, and will only allow a certain amount of mass through before collapsing.
** This was also how the original EVE Gate worked in the backstory. It lasted several hundred years before collapsing and was considerably larger, but the principle was the same.
* ''VideoGame/ConquestFrontierWars'' has naturally occurring wormholes to travel between systems, but then they somebody starts making ''artificial wormholes'' and things get a bit complicated, then someone else steals that technology..
* Wormholes in ''NexusTheJupiterIncident'' act as rapid transit between remote star systems. However, the latter stages of the game reveal that [[spoiler:they were created by the BigBad Mechanoids as a byproduct of them altering the universe]].
* The only mode of system-to-system travel in the ''SpaceEmpires'' series, as there is no FTLTravel. Some of them can be [[PointOfNoReturn one-way only]], though most are two-way. Random wormhole events can also fling your ships (or even ''bases!'') hundreds of LY across the map, as a sort of... ''BlindJump'' meets ''NegativeSpaceWedgie''.
* In ''VideoGame/HaegemoniaLegionsOfIron'', wormholes are naturally-occurring space phenomena that allow rapid travel to other systems. The only other way to travel to other system is via an experimental technology that creates temporary one-way wormholes to "wormhole probes" which only becomes available in the latter stages. Wormholes can be blocked by Darzok-developed probes or natural events.
* The Protoss of ''VideoGame/{{Starcraft|I}}'' and ''VideoGame/{{StarCraft II}}'' employ some sort of wormhole-like "warp gate" to summon units to the battlefield instead of producing them. Also, plot-relevant Warp Gates, Warp Conduits and other variations on the technology are encountered throughout the campaigns and books; mention is made of a [[PortalNetwork Warp Network]] connecting many Protoss worlds together, though their empire makes use of [[FasterThanLightTravel faster-than-light]] starships as well.
* In the second ''VideoGame/MasterOfOrion'', some planets are connected by a wormhole that allows a ship to travel between the systems in a single turn regardless of the race's propulsion tech. The wormholes can span distances anywhere from a few parsecs to going from one side of the galactic map to the other.
** A one-time special event can also create a temporary wormhole for a ship/fleet in transit, letting them finish their trip at the start of the next turn, regardless of how long they would normally have had remaining.
* ''VideoGame/SpaceRangers'' has "black holes" (though their name is just pilots' slang) that randomly appear on the edges of star systems, and hurl you into a random system (be it one hyper-jump away or 50 parsecs into enemy territory). They also contain [[SubspaceOrHyperspace hyperspace]] [[PocketDimension pockets]] inhabited by unidentified ships.
* In ''VideoGame/FreeSpace'', Subspace travel utilizes "Subspace Nodes", which are essentially wormholes that link together certain regions of space.
* Typing in "wormhole" in the ''{{VideoGame/Scribblenauts}}'' games will spawn a green portal that can't be directly interacted with. After a couple of seconds, the wormhole will automatically vanish and spawn a random monster, ranging from a simple mutant or alien to Cthulu.
* In ''[[VideoGame/CommandAndConquer3TiberiumWars Command And Conquer 3: Tiberium Wars]]'', the [[StarfishAliens Scrin]] are ''all'' about this. Production structures are just anchors for wormholes reaching back to their fleet beyond Neptune (with the wormholes themselves being spherical, iridescent orbs of spatial disturbance and exotic matter) which get sucked back into the hole upon destruction. They employ the same technology to create two-way wormholes that allow them to teleport their units around the battlefield (but, being two-way, the enemy can send their own units back through them), and in their Rift Generator superweapon which opens one between your target and outer space, which will start to suck stuff (like infantry, vehicles, and structure armor) away. Finally, there's the 19 Threshold Assemblies, enormous towers that were meant to act as indestructible planet-scale Tiberium extractors and portals to ship the stuff back to their "Ichor Hub".
* While they're not specifically called "wormholes", the [[HyperspaceLanes star lanes]] in ''VideoGame/Ascendancy'' definitely behave like the typical video game variant. Ships need a star lane drive in order to "[[AllInTheManual [allow] the ship to overcome the barrier of gravitational turbulence at the opening and slip into star lane space]]". Star lane hyperdrives are the faster versions of regular star lane drives. Also, the more you have of either, the faster your ship moves through star lane space. There are regular star lanes (blue) and the so-called "red links", which are, basically, slow star lanes that are, usually, longer.

[[folder:Webcomics]]

* In ''Webcomic/SchlockMercenary'', the "teraport" drive works by essentially sending every subatomic particle through its own wormhole. There are also "[[CoolGate wormgates]]", which theoretically produce a single wormhole big enough to pass entire starships. The wormgates can also output to multiple gates, acting as a duplicator; an entire arc centers around [[AncientConspiracy what the gates' owners were doing with this capability]].

[[folder: Web Original ]]

* Integral to the existence of society in ''OrionsArm'' due to the lack of any other sort of FTL travel. Actually traveling through them is time consuming and difficult, their main use is to transfer massive amount of information between star systems.
** It takes so long because traversible wormholes need a "transition zone" clear of all massive objects that is at least 654 AU in diameter (over eight times that of the entire solar system). For some reason nanoscale wormholes used for data transmission don't need that much space.

[[/folder]]

[[folder: Western Animation ]]

* ''Anime/{{Interstella 5555}}'' features a wormhole located behind the moon that connects our solar system to another. It's particularly dangerous to use, and Shep's ship is badly damaged trying to navigate it.
* The ''InvaderZim'' episode "A Room With a Moose" had Zim attempt to send the rest of his class (but especially Dib) through a wormhole to the eponymous [[CosmicHorror room with a moose]]. It was not stated whether this was in their dimension or another.
* In ''ReBoot'', perfectly spherical "portals" connect different systems together. The "other side" is visible from all angles of viewing, distorted by the curvature of space around the opening--this is arguably the most realistic depiction of wormholes in any TV series, bar none. (Rather ironic, as ''ReBoot'' [[CyberSpace doesn't take place in the physical world]] and so could have easily justified a wholly ''unrealistic'' depiction.)
* ''WesternAnimation/{{Futurama}}'':
** In "Roswell That Ends Well", radiation from a supernova combined with radiation from Fry putting aluminum in a microwave oven to create a wormhole that sends the Planet Express crew back in time. They have 24 hours before the wormhole closes, but need microwaves to make the return trip.
** "Into The Wild Green Yonder" ends with the crew flying into a SwirlyEnergyThingy in was was supposed to be the (second) SeriesFinale. When the show was UnCancelled, it was {{retconned}} to being the Panama Wormhole, Earth's main interstellar shipping channel.
* On ''Series/MonstersVsAliens'', Dr. Cockroach tries to invent a teleportation device in short notice to use to get around long distances during missions, but mostly to show up his rival, alien ChildProdigy Sqweep. He manages to create a working wormhole, but unfortunately, it can only go a distance of twenty feet. Also, it turns out to be lactose intolerant, somehow. He tries to pass it off anyway, and HilarityEnsues.

!!!Black Holes As Wormholes

[[folder:Film]]

* ''Film/TheBlackHole'' treats its title menace, a collapsed star, as a wormhole. And not just in theory; when we finally travel into it, it is a wormhole.
** Though some interpretations of the ending see it as the characters travelling into the afterlife, making it a subversion.
* ''Film/EventHorizon'' uses black hole as wormhole, ''[[HyperspaceIsAScaryPlace a wormhole that is connected to hell]]!''
** Technically, they use a "quantum singularity" (as in semi-controlled artificial black hole) to power the ENGINE which creates a wormhole. Somehow. Still goes to hell though.
* ''Film/TheGiantSpiderInvasion'' has a miniature black hole(that can be contained in a meteor and impact the Earth without compressing the whole thing) that apparently leads to the spider dimension. Also it can be closed off by filling it with [[{{Technobabble}} SCIENCE!]]
* The 2009 ''Film/StarTrek'' features an UnrealisticBlackHole that functions exactly like a wormhole leading to the past...when it isn't instead acting like a black hole by destroying things [[FridgeLogic with no explanation of what makes it act one way or another]]. Or maybe two different phenomena that look exactly the same? Confusing as it is, note that the Franchise/StarTrek franchise has used both wormholes and black holes on many occasions, but never mixed them up before. On a couple of occasions, black holes were used for time travel not by flying through them but by a by-product of the black hole's gravity, or warping ''near'' a black hole, or some other technobabble. This is not a case of getting the terms mixed up; the black hole is explicitly created by a collapsing star, which is (roughly) how real black holes form.
** Except the black hole in that movie wasn't created by a collapsing star, the first one was created when Spock used the "red matter" to stop the "supernova" that was going to destroy the galaxy. Because that's what red matter is used for, creating black holes.
** Also, the only times the black holes are used as weapons, they're created ''inside'' their targets, and since Spock and Nero's ships were displaced so far in time entering the initial black hole from opposite sides, presumably the same would happen to anything that gets swallowed by such a black hole, resulting in parts and pieces of the targets being sent to random time periods separate of each other, unless the whole thing comes through in one (inside-out) piece.
* The wormhole-like phenomenon connecting the Klaatu Nebula to the Solar System in GalaxyQuest is explicitly identified as a black hole. This one has an added bonus of super-accelerating spaceships that travel through it.
[[/folder]]

[[folder:Literature]]

* The ''[[HumanxCommonwealth Flinx and Pip]]'' novel ''The End of the Matter'' features a white hole used not for transportation but to destroy (slowly) a black hole of equal but opposite mass. This is of course [[UnrealisticBlackHole nearly as unrealistic]] as the trope being discussed.
* In ''Sphere'', the [[spoiler: future ship]] used a black hole that ''creates'' a wormhole, using a [[http://en.wikipedia.org/wiki/Kerr_metric Kerr metric]]; the black hole spins so rapidly that it warps nearby spacetime so that two distant locations and times touch.
* While the word "wormhole" is never used in ''Angel Station'' by Creator/WalterJonWilliams, all ships use captured black holes in order to perform FTL jumps. This requires precise calculations, which are done perfectly by one of the protagonists, because she's a "witch", a genetically-engineered girl with the ability to see and alter electron motion. Opening a "tunnel" creates in a massive radiation wave that can damage anything for thousands of miles, meaning jumps have to be made far away from planets or other ships. It is also revealed that [[spoiler:aliens use the same method]]. Apparently, any ship can be equipped with devices for capturing black holes. Why they don't get torn to shreds by gravity is never brought up.
* Joe Haldeman's ''Literature/TheForeverWar'' uses "collapsars" to cover vast interstellar distances in the blink of an eye. These collapsars (short for collapsed stars) are probably meant to be black holes. Although transit through collapsars is instantaneous, getting ''to'' a collapsar, and then getting from the destination collapsar to where you want to finally end up, can take decades due to the fact that they're so spread out in space.

* ''BlackHoleHigh'' originally called it a black hole, though they later speculated that it was actually a wormhole and preferred that term, despite occasionally reverting to the less accurate term for its mnemonic transfer ("Black Hole" also sounds a lot like "Blake Holsey", the name of the school). Wormholes can do [[GreenRocks just about anything]] in this show.
* In ''Series/FirstWave'', Joshua claims the Gua use "white holes" to transport objects from their planet.
* ''{{Space 1999}}''. Moonbase falls into a 'black sun' and, as per the black hole/white hole theory, comes out a white hole. Intact. Without everyone and everything being compressed into tiny tiny tiny pieces.
* A white hole appears in the ''Series/RedDwarf'' episode "[[ExactlyWhatItSaysOnTheTin White Hole]]". It spat out the matter and ''time'' that a black hole swallowed up, leading to short time loops and similar disturbances.

* ''{{Spore}}'' treats its black holes as wormholes, and in fact often names one as the other and vice versa.
* ''{{X-COM}} Interceptor'' features black holes all over the sector that can wreck havoc on your ships and probes. Playing through the game and researching the alien intentions reveals that [[spoiler: there is exactly one black hole that is actually a worm hole to a pocket solar system, where the aliens are constructing their doomsday weapon, and the game becomes a race against time to discover the method to use the wormhole to reach the pocket dimension and destroy the weapon before it's completed.]]
* In ''VideoGame/{{Gateway}} II: Homeworld'', the player uses a [[{{Precursors}} Heechee]] ship to go through a black hole that leads to a pocket universe, which is the sanctuary of the entire Heechee race, who hid there after discovering the [[AbusivePrecursors Assassins]]. Apparently, only certain ships are able to safely pass through the black hole, and it requires certain devices, which the Heechee promptly remove from the ship, preventing the player from leaving.

* One RealLife [[ScienceMarchesOn outdated]] theory proposed that black holes are the counterparts of "white holes" located elsewhere. All of the matter and energy falling into a particular black hole is supposed to be ejected from its corresponding white hole. But even white holes are subject to their own "[[OurTropesAreDifferent Ours are different]]" among the scientific community: Dr. Stephen Hawking suggests that the "time reversal" of a black hole is ''also'' a black hole; another common perception is that white holes ''recede'' faster-than-light from attracted matter.

[[http://en.wikipedia.org/wiki/Tesseract Real Tesseracts]] have nothing to do with this, being a geometric concept related to cubes (basically, a Tesseract is to a cube what a cube is to a square). Wormholes were not topical at the time.
* ''QuantumGravity'': There are portals between realms used to get from one to the other. Or into I-space.
* The [[Literature/HonorHarrington Honorverse]] has several wormholes but rather than a tunnel in space they are described as points where extremely powerful standing grav-waves that normally exist in hyperspace overlap with real space and allow effectively instantaneous travel between their two ends. They all come in clusters of at least two and a large portion of Manticore's wealth comes from shipping fees of their own six, later seven, terminus wormhole junction, the largest in the known galaxy.
* In ''{{Necroscope}}'' a "white hole" crash landed on a [[EldritchLocation Vampire World]] creating a small one-way wormhole that links it with ours (specifically [[{{Uberwald}} Romania]]). A few millennia later a PhlebotinumOverload in [[SovietSuperscience Russia's]] ambitious continent-wide DeflectorShield creates a much bigger wormhole in the heart of the then U.S.S.R. The twist is that each wormhole is a one way trip, but by using both you can turn them into a superhighway.
* In the ''Literature/CarrerasLegions'' series, Earth and Terra Nova are connected by what's referred to as a rift that allows nearly instantaneous transition between the two star systems, the only FTLTravel option for humanity.
* In ''Literature/ThePentagonWar'', "hyper holes" are created by detonating very expensive hyper bombs. If two hyper bombs are set off simultaneously, and pointed directly at one another, the two hyper holes will be permanenly linked and thus create a tunnel between them through parallel space. The five inhabited star systems are linked together via these hyper hole tunnels, which also form natural choke points for invasion when they go to war with each other.

* ''{{Lexx}}'''s fractal cores, glowing swirly points in space where the [[TheMultiverse Two Universes]] intersect.
* Jumpgates and jump points in ''Series/BabylonFive'' are very much wormhole-like on their ends, though the big expanse of hyperspace in between bears little resemblance to the theory. Additionally, nothing prevents a ship from going off-course, although this usually results in the ship getting lost in the constant gravitational eddies of hyperspace, and getting lost in hyperspace is usually a death sentence.
* All the strange things in ''[[BlackHoleHigh Strange Days At Blake Holsey High]]'' are handwaved by the black hole/wormhole thing.
* Wormholes haven't actually appeared on ''Series/{{Supernatural}}'' (unless you count a few magic portals), but they have been mentioned. When [[TricksterArchetype the Trickster]] is interrogated on where a missing skeptic is, he says smugly "He didn't believe in wormholes. So I dropped him in one."
* The dimensional portals in ''Series/{{Angel}}''.

* In {{Starfire}}, every accessible star system is home to one or more naturally-occurring "warp points." A warp point provides an FTL link to another specific warp point in another star system (or, occasionally, to a warp point floating deep in interstellar space). Sometimes, one of the two warp points that forms a warp-link may be "closed" (totally undetectable unless you happen to see something coming out of it), which means there may be undiscovered warp points lurking about in any star system. (This created a dire threat to the Terran Federation during Interstellar War IV.)
* In ''TabletopGame/WerewolfTheApocalypse'', Zmei (Wyrm dragons) can tear a hole in the fabric of reality and escape to Malfeas. Any creature who follows the Zmei into this portal acquires a permanent derangment and runs a high risk of insanity.
** To enter or exit the Umbra, Gurahl (werebears) tear a temporary wormhole into the fabric of reality.

* ''VideoGame/KingsQuestMaskOfEternity'' has portals that only go between two specified points, and operate on switches.
* Stormgates from {{Pirate101}} are whirlpool like wormholes act like portals that allow pirates to sail to through the stars to different parts of the Spiral.

* Because black holes don't mesh very neatly with quantum mechanics some physicists have put forward the idea of a [[http://en.wikipedia.org/wiki/Black_Star_%28semiclassical_gravity%29 "black star"]] which is like a black hole, but not.
