14Virtually all space ships in ScienceFiction have some form of artificial gravity. The technology behind this is [[{{Handwave}} never quite explained.]]
15
16In SpaceOpera, artificial gravity is the ''last'' thing that breaks when a ship is damaged. You might have lost shields, weapons, drive systems, and half the hull, but things will still fall when dropped. It might make sense energetically, as there is no (1st Law) reason for an artificial gravity system to consume a significant amount of energy. Artificial gravity is also essential for long-term flights, for if you spend too long in Zero G, then your muscles will become a painful, squishy mush once you get back to regular gravity.
17
18One major reason for this in live action is that the only reasonable way to simulate zero gravity without leaving Earth entirely involves something called parabolic flying in cargo aircraft (such as UsefulNotes/{{NASA}}'s "[[NamesToRunAwayFromReallyFast Vomit Comet]]"), which costs a lot of money, only gives you about thirty seconds of zero G at a time, and isn't the world's best thing to build a set in (although that's exactly what they did for the film ''Film/{{Apollo 13}}'' and the series ''Series/SpaceOdysseyVoyageToThePlanets''). Of course, there are cheaper ways to simulate it using WireFu and camera tricks — but all in all it's a hell of a lot easier to simply HandWave the whole issue away.
19
20Also, once you have the knack of making gravity, switching it off shouldn't be that much of a problem, right? Cue the anti-gravity hovercraft. You might also use it for InertialDampening, to make a ReactionlessDrive, or make it so WeWillAllFlyInTheFuture.
21
22Related to GravitySucks. NoGravityForYou is what happens when characters get smart about the FridgeLogic of this trope. When it's a superpower, you get a GravityMaster.
23
24Hard Sci-fi tends to avoid the idea that artificial gravity can be generated out of nothing. Typically, the only artificial "gravity" you encounter in Hard Sci-fi is either the result of [[CentrifugalGravity spinning the ship or habitat]], or the entire ship accelerating at one G. Either that, or everyone just floats around inside their spaceships.
25
26Many times a show set in space will brush off the gravity issue with "[[HollywoodMagnetism magnetic shoes]]". This bit of ArtisticLicensePhysics will magically affect everything a person is wearing and everything in the room, while in reality wearing shoes with magnets in them would only anchor your feet to metal floors — not your arms, hair, the coffee in your mug...
27
28See CentrifugalGravity if the ship generates gravity by rotating.

30An AcceptableBreaksFromReality trope.
31
32----
33!!Examples:
34[[foldercontrol]]
35
36[[folder:Anime and Manga]]
37* ''Manga/{{ARIA}}'', set on Mars (a.k.a. Aqua) matches Earth's gravity perfectly. However, it requires a group of underground gravity technicians called Gnomes to make this happen. Al, one of the Gnomes, is a recurring side character. Due to ''ARIA'''s nature as a feel-good series, though, just how this artificial gravity works is left unexplained.
38** According to the manga, they use some strange, very high density crystal only found on Mars as a gravity source, and send it to parts of the planet where it's needed through pipe networks controlled by an organ-like instrument. Best not think about it too hard.
39* ''Manga/CannonGodExaxxion'' does interesting things with this trope. Rather than simply a HandWave for people walking around a spaceship like it was an earthbound movie set, they explore all kinds of neat stuff you can do once you've made gravity and inertia yours, including, but not limited to:
40** Allowing HumongousMecha & other large targets to flout the SquareCubeLaw, even allowing things to fly that by all rights shouldn't. An interesting visual metaphor Kenichi Sonoda often uses for this effect is to turn the panel upside down when a gravity jump is in effect.
41** Creating destructive gravity waves, DeflectorShields and {{Tractor Beam}}s.
42** Increasing the force of blunt attacks, enabling mechs to perform a literal MegatonPunch.
43* The titular museum from ''Anime/DoraemonNobitasSecretGadgetMuseum'' have a Zero-Gravity Exhibition Hall, where objects on display are lined up on walls and the ceiling, and visitors can literally walk on them.
44--> '''Nobita''': I don't know where's down in this room...
45* ''Anime/SpaceBattleshipYamato'' plays this trope deadly straight. Seems to come along with SpaceIsAnOcean. The Yamato's operations are badly disrupted when the gravity fails in season 2. They are actually unable to launch their fighters, what with the fighters floating around wildly in the hangar.
46** ''Anime/SpaceBattleshipYamato2199'' similarly plays this trope straight with the Yamato at first, however the fighter maintenance bay is shown to operate with zero-G. Pre-Yamato ships are also shown without artificial gravity, instead showing characters wearing magnetic boots to compensate.
47* ''Anime/SolBianca'' had a scene where one space pirate complained about the gravity being off. Meanwhile the other one was fixing the ship told them to stop complaining and wait it out
48* ''Anime/DragonBallZ'': A recurring feature; first there's the ship that Bulma, Krillen, and Gohan take to Namek. Then Frieza's massive ship. After that, the pod Goku takes to Namek, which helps him train by simulating 100x Earth's gravity. Finally, the pod Vegeta trains in on Earth which simulates up to 500x Earth's gravity (he's never shown going above 450x... such intense gravity is very dangerous even for someone as powerful as him).
49* In ''Literature/FullMetalPanic'', the Lambda Driver generates force in accordance with the will of the user. Given enough power, this can be used as an anti-gravity system. As seen on the Arm Slave known as Behemoth, when the cooling system for the generator is destroyed, the Lambda Driver shuts down, and the massive robot collapses under its own weight.
50* ''Franchise/{{Gundam}}'':
51** The franchise is quite realistic in its use of artificial gravity, especially in the Universal Century continuity. The main source of artificial gravity here is inertia, which explains why certain shots show [[SpaceStation space colonies]] spinning around.
52** ''Anime/MobileSuitGundamIronBloodedOrphans'' is the first entry to have actual artificial gravity on spaceships, no spinning required. How it works hasn't been explained beyond the fact that "Ahab Reactors" make it possible.
53* ''VisualNovel/AokanaFourRhythmAcrossTheBlue'' is based on [=Grav-Shoes=], which let the local citizens fly and play the FictionalSport, Flying Circus. Kind of a cross between baseball and [[Franchise/HarryPotter Quidditch]].
54[[/folder]]
55
56[[folder:Comic Books]]
57* Gallimaufry Station in ''ComicBook/BuckGodotZapGunForHire'' has artificial gravity that can easily (and with some precision, say, on about a sector level at least) be dialed up or down to incapacitate troublemakers, even {{Heavyworlder}}s like Buck.
58* In the ''Franchise/{{Tintin}}'' book ''Explorers on the Moon'', the Moon-Rocket simply uses its own acceleration, equal to Earth's gravity outside take-off and landing, as its gravity source, since its decks are arranged such that it always goes "up". The engine gets turned off a few times, both accidentally and intentionally, which has the effect of turning off the rocket's ability to keep the passengers on the floor.
59** The rocket turns around mid-flight to decelerate at the same rate for the second half of the trip. This requires turning off the engine and restarting it, which is the "intentional" part.
60** Characters also use magnetic boots when this happens, and while on the Moon.
61* In pre-ComicBook/{{Crisis|on Infinite Earths}} Franchise/{{Superman}} comics, [[SchizoTech despite all its advanced technology]], Krypton had no space program until Jor-El perfected anti-gravity. [[JustifiedTrope This makes some sense]] when you consider what a monstrous gravity well their rockets had to escape. (Pre-ComicBook/{{Crisis|on Infinite Earths}} Krypton was portrayed as enormously massive, so at least part of Superman's powers derived from his being a HeavyWorlder.)
62* In ''ComicBook/UniversalWarOne'', all spaceships use anti-Gravity engines. When the power generators of the space station ''Alpha'' are destroyed, the artificial gravity breaks immediately. Best not to think about how it happened: [[spoiler:the "inventor" of anti-G had only come up with a theory. A time-traveler from the anti-G-using future made one from scratch and showed it to him, allowing anti-G technology to become widespread and spaceships to become feasible.]]
63* 1980's British ''Starblazer''. Multiple examples, including the Gravitator (created an anti-gravity field), the grav sled and grav cart, gravity neutralizers and grav chutes (parachutes with anit-gravity).
64* Usually goes unnoticed in ''ComicBook/PaperinikNewAdventures'', but was involved in the plot twice:
65** In [[Recap/PaperinikNewAdventuresS1E6TheDayOfTheColdSun "The Day of the Cold Sun"]] the Raider disguised as Angus suggests that professor Seamus Hogg should use it for the containment of an experimental fusion reactor, and [[GivingRadioToTheRomans is about to explain how to build a generator]] when the real Angus shows up.
66** [[ChekhovsGun Many stories later, Seamus Hogg is shown dabbling with artificial gravity]]. However, his generator was faulty, resulting in [[spoiler: the flow of time going literally out of its banks]], with one of the most nightmarish scenarios in the series until [[spoiler: Paperinik, Lyla and the Raider travel back in time and destroy it before activation]]. Too bad he only knows that the generator had worked...
67* ''ComicBook/Superboy1994'': Knockout's custom prison cell keeps her floating in zero gravity.
68* ''Franchise/WonderWoman''
69** ''ComicBook/WonderWoman1942'': The Saturnians have reverse gravity rays, which cause gravity to work in reverse on those who've been struck by it making them fly up to the ceiling of whatever room they're in.
70** ''ComicBook/WonderWoman1987'': While no explanation is given for how artificial gravity is generated aboard Sangtee Empire ships it is noticeably absent from smaller ships and is significantly weaker than earth gravity, allowing people to jump much further.
71[[/folder]]
72
73[[folder:Comic Strips]]
74* Many of the technologies in early ''ComicStrip/BuckRogers'' comics derive from [[{{Unobtainium}} inertron,]] an artificial substance which is repelled by gravity. Strapping a disk of inertron on your back as a "jumping belt" makes you buoyant enough to jump great distances, float slowly downward from great heights, or fly with only a tiny [[JetPack jet backpack]]. Most flying or hovering vehicles also contain the stuff.
75[[/folder]]
76
77[[folder:Fan Works]]
78* ''Fanfic/RocketshipVoyager''. The eponymous NuclearTorchRocket is built like a skyscraper to take advantage of the pseudogravity effects, but everyone floats about in null-gee when they're not at constant acceleration. Artificial gravity technology is an OutsideContextProblem even among the aliens who use it, who are tight-lipped about where they got such technology.
79[[/folder]]
80
81[[folder:Film — Animated]]
82* ''Franchise/DisneyFairies'': Pixie Dust is required for fairies to fly, and applying it to inanimate objects causes them to float like balloons. The latter is how Tinker Bell invents a pseudo-hot air balloon.
83* Club 666 from ''WesternAnimation/RockAndRule'' is an anti-gravity club. Basically a large, spherical nightclub where people can walk all over the walls and ceiling.
84* The R.L.S. ''Legacy'' in ''WesternAnimation/TreasurePlanet'' is equipped with artificial gravity. [[spoiler:During the fight with Mr. Scroop, B.E.N. accidentally disengages the A.G. while playing with plugs, and Jim sends Scroop flying through space forever.]]
85* ''WesternAnimation/WallE'' was rather odd about this - the Axiom apparently had artificial gravity, but not InertialDampening.
86** It's mentioned that the ship having microgravity is why the populace are so fat and weak but WALL•E and EVE don't move any differently than they did on Earth.
87[[/folder]]
88
89[[folder:Film — Live-Action]]
90* ''Film/{{Alien}}'' is one of the few movies where they make a point of switching on the artificial gravity when leaving the planet.
91* ''Film/Apollo13'' depicted zero gravity the hard way: by building spacecraft sets in the NASA zero gravity training aircraft (the Vomit Comet) and filming in it for a month. Far from all of the scenes inside the spacecraft were done this way; a lot of it was done with harnesses and bellyboards and careful framing.
92* ''Film/Armageddon1998'' has a bizarre relationship with this trope, even by scifi standards. Perhaps the most egregious example: The film specifically addresses the fact that the asteroid would have little or no gravity and gives the characters special suits and equipment with "thrusters" so they don't float away while out on the surface of the asteroid. Yet when the characters are inside their space shuttle, which is ''parked right on the asteroid'', they walk around unsuited as though under normal Earth gravity.
93* ''Film/{{Barbarella}}'' switches it on after doing her [[BestKnownForTheFanservice infamous zero gravity striptease]].
94* ''Film/TheBlackHole'' had this function as one of Dr. Reinhart's impressive inventions: a gravity field astonishingly powerful enough to not only have regular gravity in the ship, but also to keep the entire ship itself in a secure stationary position just beyond the event horizon of a black hole! Whereas the spaceship that discovers it is weightless except under acceleration. Left unaddressed is that the layout of the ''Cygnus'' (especially the control tower) only makes sense with artificial gravity, so it must have been designed with some sort of artificial gravity in the first place.
95* When the quadjet in ''Film/CaptainMarvel2019'' first enters orbit, we get a few seconds of everybody floating until Carol turns the gravity on. All the alien ships seem to have it on all the time.
96* ''Film/DestinationMoon'' (1950), loosely based on the book ''Rocketship Galileo'' by Creator/RobertAHeinlein (who was also a technical adviser for the movie), went to great lengths to make the film as accurate as possible, given what was known at the time or theorized to be possible based on existing knowledge, including using wires to simulate a lack of gravity inside the cabin of the rocket while it was on the way to the moon.
97* ''Film/EventHorizon'' was originally supposed to avert this trope as the creators wanted the entire movie to be done in zero gravity. However, doing so would have been too expensive and would have taken them over a decade, as stated in the making-of documentary, and the characters are only in zero gravity when they first enter the Event Horizon, before turning on the artificial gravity drive.
98* ''Film/ForbiddenPlanet'' like ''Film/{{Alien}}'' is a rare example of the crew switching it off when landing on the planet.
99* In ''Film/GuardiansOfTheGalaxy2014'', [[BadassAdorable Rocket Raccoon]] orchestrates a prison break by turning off the artificial gravity everywhere but in the guard tower, then flying said guard tower through the rest of the base.
100* ''Film/Lifeforce1985'' uses the surprisingly realistic example of applying constant acceleration to a ship in space, and also shows them realistically in zero G after they decelerate to make their rendezvous with Halley's Comet. Of course there's a time limit with applying constant acceleration as one would be traveling at the speed of light after 354 days, but the movie does not say how long the ship was accelerating at 1 G.
101* ''Film/{{Outland}}'' takes place on Io, a moon of Jupiter that has only 18% of Earth's gravity. It's not explained how people can walk about normally until halfway through the movie, when we see a line of cells marked "ARTIFICIAL GRAVITY OFF" (the prisoners are kept floating in mid-air so they can't escape).
102* In ''Film/{{Pandorum}}'', the ''Elysium'' has artificial gravity throughout; it would be tough to justify the film's BeePeople being able to make traps that utilize gravity otherwise. [[spoiler:But then the ''Elysium'' is revealed [[TomatoSurprise to have crash landed onto the planet it was headed for]] over a century before the events of the movie, thus subverting this trope very, very hard as by then the planet's gravity had taken over.]]
103* A loading bar showing the gravity quickly rise to 100% appears on the glass as Carolyn Fry comes out of stasis at the start of ''Film/PitchBlack''.
104* ''Film/PlanetOfTheApes1968'' has it in the opening scene; we clearly see Taylor walking over to his cryosleep pod to get inside.
105** Interestingly, this ship makes a cameo on a news report in ''Film/RiseOfThePlanetOfTheApes'' and we're shown more realistic astronauts floating in zero g.
106* ''Film/ProjectMoonbase'' has people walking along the corridors of a space station ''[[GravityScrew upside down]]'' past people going the other way due to its variable gravity. They avoid floating off the floor because they're wearing "magnetic shoes". Signs request that you "PLEASE DO NOT WALK ON THE WALLS".
107* ''Film/QueenOfOuterSpace''. After crashlanding on an unknown planet, the crew of the spaceship think they might be back on Earth, and check this by turning off the artificial gravity. As the gravity meter isn't on zero, they know they're not in Kansas anymore.
108* The SpaceStation at the start of ''Film/{{Saturn 3}}'' has people walking on the ceiling as well as the floor.
109* In ''Film/StarTrekVITheUndiscoveredCountry'', the artificial gravity in the Klingon ship is damaged immediately by torpedoes. Although this is probably more to do with [[RuleOfCool the rule of cool]] of having a zero-G gunfight than any attempt at hard science fiction, it is notable, because rare in Star Trek was Zero-gravity ever used. No matter how well beaten a ship was the gravity always worked through thick and thin. Life support out? Power completely lost? Gravity's still on.
110** This has a HandWave in the Star Trek technical manual, where they state the gravity generators continue producing 80% of their normal gravity for some period of time without power. We hear this in the background of several Star Trek episodes "Gravity down to 80%."[[note]]The real explanation for this is that they simply reused the tape of damage reports playing in the background. Thus every time the ''Enterprise'' was attacked, the gravity went down.[[/note]]
111* ''Franchise/StarWars'':
112** All ships from the ''[[CoolStarship Millennium Falcon]]'' to the [[KillSat Death Star]] have artificial gravity. It's not clear if it exists or is necessary for one-man fighters, although in ''Franchise/StarWarsLegends'' they do have [[InertialDampening inertial compensators]] (which are often "dialed down" slightly so pilots can "feel" what their craft is doing). The mega-cheap TIE Fighters explicitly don't have cockpit gravity or atmosphere in ''Legends'', but it's assumed all the others do.
113** The Death Star even exhibits variance in gravitational orientation in the movies, if you're looking for it. All the docking bays have their gravity at a 90 degree angle to the surface of the Death Star (craft fly straight in and "land"), but in the Emperor's tower in ''Film/ReturnOfTheJedi'' the characters' feet face down towards the surface of the Death Star as if it's a building on a planet. This points out gravity manipulation pretty clearly.
114* ''Film/{{Sunshine}}'' is a fine example of a variant of this trope, in which gravity and air appear to be intimately connected. Everything in an air lock is floating around until the lock is pressurized... whereupon its contents crash to the ground.
115* ''Film/WomanInTheMoon'', a shockingly realistic depiction of space travel since it was made in 1929, uses the idea of constant acceleration to provide gravity. As the CaptainsLog specifically notes, once they turn off the engines, stuff starts floating.
116[[/folder]]
117
118[[folder:Literature]]
119* In ''Literature/{{Aeon 14}}'', artificial gravity by pulling gravitons out of the dark layer[[note]]the imperceptible part of the universe that dark matter exists in, kind of like the underwater part of an iceberg[[/note]] and projecting them. In the 5th millennium only very large installations such as the thirty-kilometer colony ship ''Intrepid'' can fit them, but they're later miniaturized and become much more versatile, ultimately leading to ReactionlessDrive and the discovery of FasterThanLightTravel. By ''Destiny Lost'' graviton emitters are so common that ships don't even need to be airtight anymore. The miniaturization also allows for its use in InertialDampening.
120* Every alien spaceship in ''Literature/{{Animorphs}}'' fits this trope. When all of the Jahar's energy is taken away by the living asteroids in Andalite Chronicles, they are left floating inside their ship with no gravity. Also, Andalite dome ships have an interesting mechanic wherein it feels and looks as if you're walking off the edge of a cliff when moving from one part of the ship to another, where the new floor is at a ninety degree angle to the old, and each has its own gravity.
121* In Creator/PiersAnthony's ''Literature/ApprenticeAdept'' series, the habitable areas on Proton have earthlike gravity due to devices focusing the natural gravity of the planet into those areas: the surrounding landscape has ''lower'' gravity than normal for the planet, and is [[{{Mordor}} suffering for it]].
122* Creator/IsaacAsimov:
123** ''Literature/TheCompleteAdventuresOfLuckyStarr'':
124*** "Pseudo-grav" is the term used in this series for anti-gravity machines. They're a pervasive technology that can be set to various levels, most commonly between Earth normal and Mars normal. The difference in gravity between the natural landscape and the artificial gravity within the pseudo-grav is emphasized in each book.
125*** During ''Literature/LuckyStarrAndTheMoonsOfJupiter'', Sol scientists are working on a new project, called Agrav. Ships with Agrav will supposedly be able to ignore the effect gravity has on space-time.
126** "Literature/TheDyingNight": A technology called "grav-plating" is used to make the gravity inside the base on asteroid belt object ({{UsefulNotes/Dwarf Planet|s}}) {{UsefulNotes/Ceres}} equal to 80% of Earth-normal.
127** ''Franchise/{{Foundation}}'': Technology based on the principles of gravity first appear in "Literature/ThePsychohistorians", with an elevator functioning based on gravitic repulsion. Future engineers don't seem to develop it much further until five hundred years later, in ''Literature/FoundationsEdge'', where anti-gravity is worked into the basis for a ReactionlessDrive.
128** "Literature/NotFinal": Ganymede has underground bases with fields of artificial gravity to keep the inhabited areas at Earth-normal. Orloff and Birnam have to cross two miles of Ganymede-normal to reach Ether Station.
129** "{{Literature/Strikebreaker}}": Elsevere, a CityPlanet inside of a [[UsefulNotes/DwarfPlanets planetoid]], uses pseudogravity engines to create Earth-normal weight as they build into the rock.
130* Creator/IsaacAsimov and Creator/JanetAsimov's ''Literature/TheNorbyChronicles'': Antigrav was invented fifty years ago and the generators are now small enough to fit [[FlyingCar in your car, providing the ability to float in the air]]. The titular Norby has one built into his small [[TinCanRobot barrel-like body]].
131* [[Creator/KurdLasswitz Kurd Laßwitz]]'s ''Auf zwei Planeten'' ("Literature/OnTwoPlanets", 1897): OlderThanTelevision: In what is probably the UrExample, the Martians can create "abaric fields" which allows them to suspend their space station vertically above Earth's North Pole and to move about more easily in Earth's much more powerful gravitational field.
132* ''Literature/BeyondThirty'' is set in the 22nd century, and the protagonist starts out traveling on an airship lofted by anti-gravity.
133* ''Literature/CharlieAndTheGreatGlassElevator'': The Space Hotel has artificial gravity, so the characters walk normally inside, but the Elevator does not have this, so they float around.
134* The ''Literature/CoDominium'' setting uses only rotation or thrust to generate pseudogravity-- the amount of thrust needed for 1 G on a warship being roughly equal to detonating several multi-megaton thermonuclear warheads ''per second''. And they sometimes go to ''nine'' gees for several minutes; the limiting factor being not the engines or energy required, but how long the crew can stand the acceleration. No wonder they can [[DeathFromAbove slag planets]].
135* ''Literature/ConsiderPhlebas''. A member of Kraiklyn's Free Company [[PoorCommunicationKills who wasn't present at the briefing]] activates his antigrav and jumps off a high ledge before anyone can stop him. Unfortunately he's on a ringworld which uses CentrifugalGravity, so [[OhCrap he realises his antigrav won't work there]] moments before he hits the ground.
136* ''Magazine/CosmicStories'': The NonFiction essay, "Gravity Reversed", describes four ways to send humans to space; self-propelled rockets, projectiles, [[CentrifugalGravity centrifugal force]], and manipulating gravity. It describes recent vacuum-room tests where liquid helium that was cooled to near absolute zero started to flow upwards, defying gravity.
137* Creator/GordonRDickson's ''Literature/ChildeCycle'': An interesting variant is shown in at least one ship, where the gravity generator is sandwiched between halves of the ship, so one half is upside-down relative to the other half, and you have to dive ''down'' through a hole in the floor of one section to come ''up'' in the other. This actually seems marginally more like something possible than having every deck oriented the same way and ''all with the same gravity''.
138* The first ''{{Literature/Doom}}'' novelization made gravity into something akin to a plot point at one early point in the story. The Martian moons have artificial gravity fields built by the Gate builders. This being a ''{{VideoGame/Doom}}'' novelization, the plot point was that Fly killed a monster with its help. This is notable considering that the video game didn't even have proper ''height'' let alone gravity.
139* Creator/HarryHarrison's ''Literature/TheDalethEffect'': The discovery of a way to reduce gravity drives the plot. The scientist who discovered the phenomenon specifically mentions that the knowledge could be used to do horrible things, such as grabbing chunks of the Moon and [[ColonyDrop dropping them on an enemy country]]. The use of the device, for example, allows a craft (which doesn't even need proper engines) to travel to the Moon within hours and to Mars within days (presumably, when Mars is near). A trip to Alpha Centauri would still take over 5 years, but this is ''much'' better than the centuries we're looking at with our current technology. [[spoiler:It turns out that the trick is actually pretty easy to figure out by scientists, once they know what to look for, and, by the end of the novel, several countries have independently filed patents for the technology]].
140* Played with in the ''Literature/EndersGame'' series. Students on the Battle School space station are told it rotates to provide gravity, with the central axis staying motionless to house the zero-g Battle Room. Some smarter students realize this explanation is ''impossible,'' because the gravity cuts off abruptly at the doorway. The only explanation is a secret source of Artificial Gravity, which Petra speculates was [[ImportedAlienPhlebotinum reverse engineered from captured alien ships]]. It's actually revealed later by Graff that humans have reverse-engineered artificial gravity generators from [[spoiler:Eros, a Bugger planetoid-turned-space-station at the edge of the Solar System]].
141** And then the author {{RetCon}}s this in the ''Literature/EarthAfire'' prequel by stating that [[MegaCorp Juke Ltd.]] already has gravity-lensing technology that it uses as a prototype mining drill and to make aircraft fly on projected gravity fields even before the Formics ever get to Earth.
142** The is fixed in the audioplay of ''Ender's Game'', where Graff mentions that it was indeed a Juke invention, whereas the Formics still didn't have it. The Little Doctor is also mentioned to be a product of that technology, originally developed as the "gravity laser" (or "glaser") designed to break down asteroids for quicker mining and actually used during the First Invasion by the Juke mining fleet to fight the enemy. Additionally, [[spoiler:Eros]] is corrected to be much closer to Earth, as it is in RealLife.
143* Creator/HGWells's ''Literature/TheFirstMenInTheMoon'' (1901) is probably the earliest example in English literature. Wells's hero travels to the moon with the help of "cavorite", a [[{{Unobtainium}} mysterious substance]] that blocks gravity in the same way a steel wall blocks light.
144* Stephen R. Donaldson's ''Literature/TheGapCycle'' goes into detail about how artificial gravity works, how it affects the engines (when going into "tach", the artificial gravity is shut off or the rotation could cause the ship to miss its target), and even how having zero G and 1G psychologically affects the crew.
145* Creator/RobertAHeinlein subverts this in some of his works, including several of the stories in ''The Green Hills of Earth'' (especially "--We Also Walk Dogs", which is about this trope), but he plays it completely straight when it's convenient to the plot for him to do so (like in ''Literature/StarshipTroopers'').
146* In the ''Literature/HonorHarrington'' novels by Creator/DavidWeber, artificial gravity is the basis of the series' distinctive "impeller drives" and coupled force fields as well as the hyperspace gravity wave-riding "Warshawski sails". Impeller drives can provide theoretically infinite acceleration, limited only by an inertial compensator's ability to prevent the crew from feeling it (usually topping out under 800 gravities). It's also the source of tractor beams which provide the basis for [[spoiler:the spider drive]], it's how bomb-pumped grasers shape the blast towards the lasing rods, and it has provided a revolution in cheap interstellar transport of goods and skyscraper design.
147** The artificial gravity is provided by adjustable "grav plating". But it's difficult to match up the gravity fields of docked ships, so the docking tube (equivalent of a gangplank) is null-''g'', and characters "swing" into the ship's gravity field.
148** Prequel novels set during the early days of the kingdom still have ''Series/BabylonFive''-type ships with most of the ship in zero-g and several habitation areas on rotating sections. It's mentioned that Havenites (that's pre-Peep Havenites, still good guys) are experimenting with "grav plates" to create ships without rotating sections.
149* In Creator/AlanDeanFoster's ''Literature/HumanxCommonwealth'' series, the method of [[FasterThanLightTravel FTL propulsion]] used by most spacefaring races is accomplished by creating an extremely powerful artificial gravity field in front of a spaceship, which then pulls the vessel towards it. This pushes the field further forward, and so forth. As the ship approaches the speed of light, the distortion induced by the field shunts it into [[SubspaceOrHyperspace "space-plus"]]. The field is also used to create artificial gravity for the ship's inhabitants.
150* ''Literature/JoelSuzuki'': Cars in Mono Realm have no roofs or seat belts - instead passengers are held in place by artificial gravity.
151* In the ''Literature/KnownSpace'' stories by Creator/LarryNiven, human spaceships at first either used inertial (spinning) pseudo-gravity, or learned to do without. At least, until the Man-Kzin Wars (the Kzinti having developed artificial gravity, which humans reverse-engineered).
152* ''Literature/{{Lacuna}}'' has artificial gravity based on some AppliedPhlebotinum introduced in chapter 1.
153* Notably {{Subverted}} in the otherwise straight SpaceOpera ''Literature/LuciferStar'' as artificial gravity only exists when the starship's drives are working and pulling them to the ship's engines (which are deliberately always put at the bottom of the ship). The rest of the time, they use magnetic boots and locks to keep everything in place.
154* Peter F. Hamilton's ''Literature/TheNightsDawnTrilogy'' has several forms of this: rotational, in the shape of the bitek or asteroid habitats; and more "sci-fi" in the form of the Voidhawks - they manipulate the shape of space-time (and thereby gravity) around them in order to move, then produce a counter-acceleration force for the crew compartments to leave a constant 1G gravitational field for the humans on board. Adamist starships have to make do with thrust acceleration. [[spoiler: In one of the short stories in the associated collection, Marcus Calvert stumbles upon an alien wreck which has actual artificial gravity - but they are forced to destroy the ship, losing the knowledge forever. However, given their eventual evident level of technology, it would be unlikely that the Kiint don't have artgrav of some description.]]
155* Creator/GregEgan's ''Literature/{{Orthogonal}}'' trilogy: Both CentrifugalGravity and the constant one-G variation are played straight as the protagonists fly their GenerationShip to an [[AlternateUniverse Alternate Dimension]] by [[ItMakesSenseInContext accelerating the ship to an infinite velocity]] at a rate of one-G for about a year. When they turn off the engines and stop accelerating, the lack of gravity unexpectedly causes their crops to fail, so they begin spinning the ship to compensate.
156* In Creator/NikolayNosov's children's book, ''Literature/DoonoOnTheMoon'', the first expedition to the Moon brings back some rock samples, one of which turns out to have [[Literature/TheFirstMenInTheMoon cavorite]]-like properties when in close proximity to a magnet. Dubbing the mineral "moonite" (or "lunite"), Doono (the smart shorty) builds a big rocket to carry a second expedition to discover the nature of craters on the Moon (he things they were formed when the Moon was being formed in the manner of bubbles popping on a pancake) and retrieve more moonite for subsequent expeditions. The rocket is spacious and even has a hold full of seeds of the giant fruit and vegetable plants that grow all over Earth (it's implied that these plants are normal-sized but the shorties are ''very'' small). The titular character is excluded from the mission for being clueless about anything and rude to many shorties. He (and another excluded shorty) sneak about the night before take-off but accidentally activate the launch. Since the rocket engine doesn't provide much thrust (most of the lifting power is due to the properties of moonite), no one else hears it take off. The two shorties end up on the Moon and then accidentally find themselves falling through a crack... and find out that the [[HollowEarth Moon is hollow]]. They keep falling with their parachutes until they land on a mini-Earth inside the Moon. When Doono has another rocket built, this one using conventional propulsion, it's much smaller, has a smaller crew, and far less comfort than the "moonite"-powered one.
157* ''Literature/PerryRhodan'':
158** Taken for granted in this universe. A portable anti-gravity generator is one of the first few pieces of alien technology that the titular hero brings back home from the moon in the earliest issues, and virtually every civilization (certainly every FTL-capable one) has artificial gravity on its ships and uses anti-gravity in lifts and vehicles. This is handwaved with the idea that working hyperspace physics by default includes some concepts of manipulating 'normal' spacetime, including gravity. Like any technology, however, the systems can't work without a power supply; a suitably wrecked but still existing starship will revert to zero-G conditions once the power cuts out.
159** Taken to its logical conclusion in the design of the BASIS (although then rarely mentioned past her introduction). A one-of-a-kind intergalactic exploration vessel designed by the Terran {{master computer}} NATHAN and at over fourteen kilometers long somewhat too big to make practical planetfall anyway, the ship uses an unorthodox more space-efficient internal layout only made really ''possible'' by artificial gravity -- for example, corridors may seem to suddenly bend sharply "up" or "down", but since gravity still exerts its pull towards the local floor a crewmember can just step across the dividing line and keep walking as though on even ground. It's still plausibly described as initially rather disorienting and humans (and others) need some time to get used to it first.
160* Creator/JackMcDevitt's ''Literature/PriscillaHutchins'': Mentioned as a fairly recent invention (except for in the first book, where [[EncyclopediaExposita newspaper and journal extracts at the end of chapters]] sometimes mentions development of anti-gravity and that this would be a logical development of that).
161* In Creator/MichaelReaves's ''Literature/TheShatteredWorld'' and ''Literature/TheBurningRealm'', the fragments of a [[EarthShatteringKaboom broken fantasy planet]] are kept in orbit and provided with localized artificial gravity by powerful Runestones, allowing life to continue on each FloatingContinent within an immense magically-preserved air envelope. Smaller Runestones are likewise used to generate normal gravity aboard flying ships that travel from fragment to fragment.
162* The ''Literature/RevelationSpace'' series takes a realistic approach; artificial gravity only exists when a spacecraft is under thrust or rotating. [[spoiler: However, there is at least one alien race that can manipulate gravity more easily.]]
163* Creator/JohnRingo plays it absolutely straight, but gets into the background and problems of artificial gravity in ''Literature/TroyRising''. One of the technologies that Tyler Vernon buys from the Glatuns is grav plates, which are capable of producing any level and type of gravity on demand (including negative gravity, ie [[WesternAnimation/RockyAndBullwinkle Upsidasium]]). It is used as a space drive, an [[Main/InertialDampening inertial damper]], and a weapon, as well as its more traditional use of providing 1G for shirt sleeve environments. Multiple characters wonder how the first one was produced by the alien race who originally came up with them, because "you need a grav plate to create a grav plate". Also, the controls for grav plates are exceedingly fussy when using them as inertial dampers in high-velocity (up to 400G) maneuvers: a person gets [[Main/ChunkySalsaRule sprayed all over the cabin]] when the grav plate under his seat goes haywire during a fast turn.
164* ''Literature/SectorGeneral'' has adjustable artificial gravity, which helps the doctors configure the various wards to an environment most suited for the species of patient in them.
165* The ''{{Literature/Slingshot}}'' series plays this straight in that most space ships and stations have it. It's not a given, though, as it's a power-hungry system and one of the first things to go when power generation is severely damaged. For the same reason, very small craft do not have artificial gravity.
166* E.E. "Doc" Smith flipped back and forth between hard and very soft sci-fi at times.
167** In ''Literature/TheSkylarkOfSpace'', humanity's first stumbling efforts into the void are played very hard in the gravitational sense. Later, the characters meet alien beings from whom they copy, acquire or (justifiably at times) appropriate gravity-manipulation technology, both giving them gravity without having to accelerate constantly (which they often do, being relatively non-energy-limited in later books) and enabling them to survive some seriously brutal manoeuvres without being shaken to bits in their seats.
168** The ''Literature/{{Lensman}}'' universe has portable gravity dampers for human personnel assigned to ships of races which are either heavy-gee to start with or have a higher tolerance of it in combat manoeuvres. In addition, parts of a ship can be tuned to high gravity to accommodate those who prefer to live and train in something closer to their home environment. By contrast, in the prequel novels, artificial gravity is a luxury reserved for spaceliners and is not bothered with in combat ships. Only in Kim Kinnison's era does it become commonplace on warships; and even then, he admits to a girl he's dancing with at a victory ball that the technology is empirical and "we really don't understand gravity, even though we make it to order".
169** In the ''Literature/FamilyDAlembert'' series, the heavyworlders who form the top ranks of the galaxy's secret service invariably end up paired with each other because they're the only ones who can stand each other's native environments - and even then, one of them finds that the extra half-gee of the place he's visiting (three vs. 2.5) makes a lot of difference when you're fighting for your life.
170*** In fact, the human heavyworlders' planets seem to top out at three gees in both the Lensman and Family d'Alembert series, which suggests Smith did some research which indicated that this was the practical maximum that humans could be expected to successfully adapt to without assistive technology. Such technology is not easily man-portable in the ''Family d'Alembert'' universe, although it is fitted to some of the larger spacecraft, and artificial gravity boosting up to twenty-five gees can be selectively turned on in individual rooms of a dwelling or compartments of a ship. This becomes a major plot point in the climax of both the first and final novels of the series.
171* ''Literature/{{Skyward}}'': The human fighters use two different kinds of grav-tech.
172** First, the [[{{Unobtainium}} acclivity rings]], which allow the fighters to levitate.
173** Second, the Grav-Caps, devices which can negate the affects of acceleration, but only for short bursts.
174* ''Literature/TheSpaceOdysseySeries'': In ''3001: The Final Odyssey'', it is shown that humanity eventually develops this, which also drives their InertialDampening and [[ReactionlessDrive Reactionless Drives]].
175* In Creator/SergeyLukyanenko's ''[[Literature/TheStarsAreColdToys Star Shadow]]'', the Strong races have gravity-manipulation technology (used to lift ships into orbit), implying the use of artificial gravity on their ships. The [[ScaryDogmaticAliens Geo]][[HumanAliens meters]] have artificial gravity on their ships. When a Russian "Buran" shuttle is docked to a Geometer ship, the latter's computer extends the ship's AG field to the shuttle. When the protagonist then gets into a fight with a more seasoned cosmonaut, he has the advantage, as he'd gotten used to AG, while the other man fights as one would in zero-g (e.g. hit and lightly push off to float to the ceiling).
176* In ''Literature/StarshipsMage'', [[SpaceFantasy gravity runes]] need to be constantly refreshed by magic. Since mages are always in demand, it's expensive to bring them in on a regular basis, which means many spaceships at dock don't have extensive artificial gravity. Ships in transit often have spinning components that allow centrifugal force to pull inhabitants to the outside of the ship. Despite the fact that mages can create their own artificial gravity fields, some, like the main character, choose to float through zero gravity spaces just like the rest of the population, to avoid drawing attention to themselves.
177* The Tzenkethi in the Literature/StarTrekNovelVerse manipulate gravity on a local scale so they can use every surface of a room for work or recreation. They consider using only the floor to be a foolish waste of available space. Also, they're psychologically uncomfortable with open spaces and prefer the sense of enclosure that comes from having workstations on every wall, floor and ceiling. The effects are shown in the ''Literature/TerokNor'' and ''Literature/StarTrekTyphonPact'' series.
178* ''Franchise/StarWarsLegends'':
179** In ''Literature/GalaxyOfFear'' there's a book, ''Spore'', that largely takes place on an asteroid that's large but not big enough for substantial gravity. A base on it has artificial gravity, but outside of it characters have to use special boots with tractor beams in them to avoid floating away.
180** The ''Literature/XWingSeries'' has a devious application of artificial gravity: [[spoiler:when Corran Horn ends up captive in the feared [[TheAlcatraz Lusankya prison]], [[PrisonersWork breaking big rocks into little rocks]] in a cave system, he notices some pieces of debris falling ''up'', and after an altercation that requires medical treatment, spots some stormtroopers walking along the "ceiling" of a corridor. This lets him put together that the prison is effectively built upside-down thanks to anti-grav systems, so any prisoners trying to escape to the surface will just end up moving deeper into the depths. This is all facilitated by the next big reveal: the prison is actually an artificial cavern complex inside the Super Star Destroyer ''Lusankya'', which would have anti-gravity components as standard.]]
181* ''Literature/TheSuccessionDuology:'' There are four types of gravity:
182## Hard gravity: natural gravity, made by large amounts of mass.
183## Easy gravity: the first type of artificial gravity. Cheap to generate, but easily overruled by hard gravity, and sufficiently variable to make some people seasick.
184## Wicked gravity: chaotically unstable artificial gravity. At short range it can tear a starship apart, at extreme range it will give the crew an increased risk of cancer.
185## Lovely gravity: wonderfully powerful and controllable, and so expensive to generate that it is mainly used for saying "We are rich."
186* Every spacecraft in ''Literature/ThisAlienShore'' has this, although it doesn't feel quite like the real thing. Even the tiny escape pod that Jamisia uses at the beginning of the story has gravity that can be turned on and off.
187* Planet-bound example: In the ''[[Literature/TheTripods Tripods]]'' trilogy, the Masters' domed cities are maintained at higher internal gravity than is normal for Earth, making life comfortable for the alien Masters and extremely arduous for their human slaves.
188* Creator/AllenSteele:
189** ''{{Literature/Coyote}}'': This novel tries and fails to avert this trope, when [[ArtisticLicensePhysics a ship traveling at a constant velocity]] of .2 C results in an effectively 1 g environment.
190** ''Literature/AvengersOfTheMoon'': After entering a top secret Solar Guard cruiser, Captain Future is told to hold on tight, whereupon Gravity Ensues after the cruiser goes to warp (handwaved as the warp bubble isolating them from the normal conditions of spacetime). The crew can't help smirking at the self-proclaimed Literature/CaptainFuture's surprise. "Welcome to the [=24th=] Century!"
191* A standard technology in the ''Literature/{{Uplift}}'' universe, so much so that at least one alien race believed that flight was impossible without AntiGravity. Many Earthclan ships still have rotating ring segments to emphasize their "wolfling" status to the Galactics.
192* ''Literature/VorkosiganSaga'': The invention of artificial gravity helps to drive the plot of ''Falling Free'', rendering the Quaddies (genetically engineered HumanSubspecies designed with legs replaced by a second set of arms + hands and free-fall adapted metabolisms) obsolete.
193* In ''TabletopGame/Warhammer40000'', Space Hulks are the smashed-together remains of lost ships that occasionally resurface from the Warp. Literature/CiaphasCain ('''HERO OF THE IMPERIUM!''') mentions the strange feeling of gravity shifting when they move from the range of one ship's gravity generator to another.
194** He also mentions antigravity vehicles used by civilians. The Imperium of Man has yet to use AntiGravity in a military context, unlike the hover-tanks of the Tau and Eldar.
195* In addition to the traditional use of this on spacecraft in the VideoGame/WingCommander universe, the "hopper" drive [[AllThereInTheManual described]] in ''Confederation Handbook'' (essentially the manual for [[Film/WingCommander the movie]]) creates a temporary gravity anomaly to effectively make the equipped ship [[FasterThanLightTravel superluminal]] (though not with the ease of use of traditional jump drives). The novels building off of the movie {{novelization}}, ''Pilgrim Stars'' and the unreleased ''Pilgrim Truth'' (for which the outline is publicly available) have an improved version of this drive that eliminates some of the limitations and can be used as a weapon, equipped on a ship that gets hijacked by Pilgrims.
196* The Carpathia uses this in the ''Literature/XandriCorelel'' books, with gravity levels varying between rooms depending on what they're used for and what species stay there.
197* Completely averted in ''Literature/TheExpanse'': normal-sized spaceships only have gravity when the engines are on. (Fortunately for them, they have an insanely efficient engine that can stay on for the entire trip.) All equipment and furniture aboard is designed with 0G in mind. Space stations, asteroid bases, and the massive GenerationShip Nauvoo use CentrifugalGravity. Magnetic boots are standard equipment for anyone living in space.
198* In ''Literature/{{Bounders}}'', the space station and the shuttle the kids take to get there use artificial gravity, which can be switched on and off.
199* Lone from ''Literature/MoreThanHuman'' builds an antigravity machine, following Baby's instructions, to help the Prodds with their truck. Pushing the lever in one direction makes the object the machine is attached to heavier, and pushing it in the other direction makes it lighter. When Lone reaches the Prodds' farm, he finds it abandoned, so he attaches the device to the truck in the field and forgets about it. [[spoiler:Hip discovers it years later and spends seven years searching for the people who put it there.]]
200[[/folder]]
201
202[[folder:Live-Action TV]]
203* ''Series/AgentsOfSHIELD'': Both artificial and anti-gravity can be created using [[{{Unobtainium}} an element called Gravitonium]]. [[spoiler: In Season 5, the Team encounters a facility and a plane using this tech in a post apocalyptic future they end up using, which Fitz and Simmons later invent when they get back to their own time.]]
204* ''Series/{{Andromeda}}'': The in-universe explanation for why the ''Andromeda Ascendant'' can maneuver like a SpaceFighter despite being a [[TheBattlestar kilometer-long capital ship]] is fine control of the ship's AG field by the AI.
205* ''Series/BabylonFive'':
206** As artificial gravity generation is a closely held secret, humans have to make do with ships that have rotating hull segments to generate centrifugal force, whereas smaller vessels had to do completely without any gravity other than when accelerating. Humans eventually get a hold on this technology thanks to [[spoiler:joining the Interstellar Alliance, as one of its advantages is sharing technology and science among the member races.]]
207** It is eventually mentioned that the tractor beams used by some of the more advanced ships are actually part of the same artificial gravity system that provides gravity and propels the ships (it propels the ship by making it "fall" in the desired direction of travel).
208** The Brakiri and the Minbari have developed gravitic weapons that effectively crush the target under its own weight. The Brakiri have developed it to be their main weapon even on warships, while the Minbari seem to find it AwesomeButImpractical and only have rings that work as hold-out weapons for diplomats, using more conventional energy weapons (augmented by artificial gravity) for everything else.
209** Narn warships canonically have no artificial gravity at all. Their ship crews are thus always depicted strapped in to their seats to avoid floating off.
210* The ''Galactica'' in ''Series/BattlestarGalactica2003''.
211** There was one scene where crew in spacesuits were shown to be carefully traversing one of the flightpods with magnetic boots. This is consistent with ships being magnetically sealed to the flightdeck.
212** Interestingly, one ship in the ''Galactica'''s civilian fleet (the ''Zephyr'') has a large and distinctive ring that rotates to provide gravity. Ron Moore wanted to do part of an episode on board it in a nod to ''2001: A Space Odyssey'', but was unable to for budget reasons. [[AllThereInTheManual Apparently]], the Colonials used to rely on this method of artificial gravity generation, and the ''Zephyr'' retains the design for novelty value (it's a luxury liner). The ring stops spinning for [[spoiler: repairs after being hit by two Cylon missiles]] and [[spoiler: when no-one is on board as the ship and the rest of the fleet are flown into the sun]].
213** There's a screen capture of the computer on Boomer's Raptor from one episode that clearly shows "Gravity Control" as an option, indicating that Colonial gravity generators have variable settings (and are presumably small enough to fit within relatively small craft).
214* In ''Series/DarkMatter2015'', the ship is equipped with this, but unlike most examples of this trope, the artificial gravity ''will'' go out if the ship has to divert power for evasive maneuvers.
215* ''Series/DoctorWho'':
216** [[Recap/DoctorWhoS31E5FleshAndStone "Flesh and Stone"]] has some fun with this. The heroes escape the Weeping Angels by jumping up to a crashed spaceship far above them, using its artificial gravity field to get the rest of the way. Then they drop through a hatch, which turns into a corridor from their perspective. Finally, the Angels drain the ship dry of power out of desperation — switching off the gravity and leaving them to plummet into a crack in time.
217** Time Lords can apparently feel the difference between artificial gravity and the normal kind. In [[Recap/DoctorWhoS35E1TheMagiciansApprentice "The Magician's Apprentice"]], the Doctor and Missy use this to deduce that the "space station" they're on is actually an ordinary building on ''an invisible planet''.
218* According to ''Series/{{Firefly}}''[='s=] supplemental materials, there is a three-part gravity manipulation system on ''Serenity'' and other ships in TheVerse; one to keep everyone down, another to make the ship float, and a third to cancel out major inertial movements in time with the drive system (See InertialDampening). All those systems, together with its inertia-cancelling drive, are colocated with the reactor in the rear bulb of the ship.
219** The artificial gravity is given a mention in one episode, where Kaylee explains that it sometimes gets interference with a planet's gravity when the ship hits the atmosphere.
220** We're also shown a scene in the pilot where the gravity is switched on once the crew are back aboard, resulting in them thumping down onto the deck.
221** Their method of {{Terraform}}ing can give a planet the size of our moon Earth-like gravity.
222* ''Series/HenryDanger'': In both the Love Shuttle and on the space station, there was artificial gravity in the two-part episode "Space Invaders". The space station had a switch that could turn it on and off, which became a plot point when fighting against Kid Danger.
223* Rabbit Hutch in Series/KamenRiderFourze has a large lever to activate this.
224* The first episode of ''Series/LostInSpace'' has the artificial gravity turned off to make repairs.
225* ''Series/TheMandalorian'' has his ship lose all power for a few moments at the beginning of an episode. The gravity generators keep working until he can restart the engines.
226* ''Series/NickyRickyDickyAndDawn'': The space simulator in "A Space Quadyssey" has artificial gravity that the quads accidentally trigger, thinking they were in space.
227* Series/NightMan's anti-gravity belt is what allows him to fly. Apparently, according to the pilot, it was planned to be standard-issue for cops of the future, along with an InvisibilityCloak and an {{Eye Beam|s}}.
228* ''Series/{{Space 1999}}'' includes "gravity shields" that provide artificial gravity, let spacecraft take off and land on planets without refueling, and allowed the moon to fly through a black hole (!). The shields stop working every time they would be detrimental to the plot.
229* In the reality TV series ''Series/SpaceCadets'', a group of gullible, ignorant people were successfully fooled into believing that such technology exists now and is in use in manned orbital flights.
230* ''Franchise/StargateVerse'': All spaceships have some sort of artificial gravity.
231** In ''Series/StargateSG1'', Ba'al has a research base dedicated to the manipulation of artificial gravity, complete with a jail cell that shares all the same drawbacks as a ForceFieldDoor.
232** ''Series/StargateAtlantis'':
233*** When Rodney and two bit characters are trying to repair an Ancient KillSat in part one of "The Siege", they're initially weightless because the satellite has been without power for millennia. Then they turn on the artificial gravity too fast and [[AmusingInjuries poor Rodney falls about twenty feet onto his back]].
234*** Samantha Carter and Bill Lee were working in a half-finished base that didn't have artificial gravity. Sam glided gracefully from point to point, while Bill... well, spaceships need barf bags, too.
235* Author Ben Bova's UniverseBible for the shortlived series ''Series/TheStarLost'' explicitly invoked artificial gravity for the Ark, but coyly refused to quantify the technology, except to note that gravity generators were likely to be large, massive and completely non-portable devices. The show did not last long enough for the specifics to become important to a story.
236* Starfleet ships in ''Franchise/StarTrek''. Even the relatively primitive ''Enterprise'' of ''Series/StarTrekEnterprise'' has artificial gravity.
237** Considering that a warp field is essentially a massive graviton field, it stands to reason that any warp-capable civilization also has AG.
238** Early in ''Series/StarTrekTheOriginalSeries'', the creators put together a tape of intercom chatter to play as background during bridge scenes. At one point one of the voices reports that "Gravity is down to point eight." This tape was used over and over, particularly when the ''Enterprise'' had been attacked, which meant that the artificial gravity went down to eighty percent a fair amount of the time. The Technical Manual's HandWave is that a gravity generator takes a long time to stop generating gravity once you pull the plug; it actually goes out as readily as any other system when the [[ExplosiveInstrumentation consoles start sparking]] but about eighty percent of the artificial gravity will remain for quite some time.
239** ''Series/StarTrekDeepSpaceNine'':
240*** In "[[Recap/StarTrekDeepSpaceNineS02E06Melora Melora]]", an alien Starfleet officer from a low-gravity world is able to lower the artificial gravity in her quarters, allowing her to leap about as she is used to, when she normally needs a wheelchair to get around in the Earth/Bajor/Cardassia-standard station gravity. She later takes out a bad guy who had taken her and other crew hostage by turning down the gravity on the runabout they're on, disorienting him long enough for her to beat him up. (She was originally planned as one of the series' leads, but repeated low-gravity scenes would have been prohibitively expensive, so she became a one-off.)
241*** In "[[Recap/StarTrekDeepSpaceNineS03E22Explorers Explorers]]", Sisko restores an old Bajoran vessel from their pre-warp age, authentic in every way... except for a gravity generator, because zero-G makes him nauseous. Cheater.
242*** In "[[Recap/StarTrekDeepSpaceNineS07E06TreacheryFaithAndTheGreatRiver Treachery, Faith and the Great River]]", Sisko outright requests O'Brien to fix the gravity in the Defiant which would require a "graviton stabilizer" and thus when Nog convinces O'Brien to find one "the Ferengi way" shenanigans happen. This would confirm that at the very least the artificial gravity in the ''Star Trek'' universe is caused by graviton manipulation.
243** In ''Series/StarTrekTheNextGeneration'', ''Enterprise'''s shuttle bay floor has a section marked "Warning: Variable Gravity Area", although it is never seen at anything that is clearly different to normal gravity.
244** In the {{novelization}} of one of the movies, Captain Kirk steps out of an Earthlike-gravity zone into a zone which recreates the much more powerful gravity of the planet Vulcan. There is then an amusing scene in which Kirk is pushed a few inches or so into the air by this sudden change, and comes back down, injuring himself in the process.
245** The bigger episodes and the movies sometimes put the characters into zero-gravity situations -- which also happen to be zero atmosphere situations, meaning they get to wear spacesuits with magnetic boots that somehow allow them to walk almost normally.
246** Artificial gravity failure has only happened twice in the franchise; on the Klingon vessel Kronos One in ''Film/StarTrekVITheUndiscoveredCountry'' and in a limited section of the ''[[Series/StarTrekVoyager USS Voyager]]'' in "Prey". Both included the aforementioned magnetic space suits, but some floating was shown, particularly in the former which also included zero-g blood floating around.
247*** It also happens (briefly) in an episode of ''Series/StarTrekEnterprise''. A cloaked alien ship is "coasting" in the NX-01's warp drive wake (effectively pulling them along with ''Enterprise'') due to their warp drive being damaged. The later explanation is that the aliens are too shy to just contact them and ask for help. The presence of the ship in the ''Enterprise'''s wake causes warp field distortions that feed back into other systems and cause malfunctions throughout the ship (the computers and crew don't know to compensate for a ship being there because they don't know that it is). At one point, the gravity fails in Archer's quarters while he is taking a shower. He actually floats up out of the shower and nice zero-G CG water floats about his cabin, until the gravity is suddenly restored and he ends up falling flat on his face, followed by being drenched.
248*** It will happen again in the upcoming animated series ''WesternAnimation/StarTrekProdigy'' if the official trailer is anything to go by.
249** Some of the [[AllThereInTheManual Tech Manuals]] published to accompany the various series have tried to HandWave away the reason why the gravity never seems to fail, even if the ship loses power. The reason is that systems generating gravity have to spin up when powered on and keep going for several hours even if the power is cut off meaning that gravity disappears slowly rather than cutting off all at once.
250** ''Series/StarTrekEnterprise'':
251*** In [[Recap/StarTrekEnterpriseS01E01E02BrokenBow the pilot episode]], a conversation between Helmsman Travis Mayweather and Armory Officer Malcolm Reed takes place where Travis asks if the artificial gravity feels a bit heavy. Malcolm replies that no, it's about normal for Earth sea level. Travis reveals that, growing up on a cargo vessel, his dad liked to lighten the artificial gravity to "put a spring in his step". In this same episode, Travis shows Chief Engineer Charles Tucker the ship's "sweet spot", right between the gravity generator and the back of the ship, where gravity reverses halfway through the room -- illustrated by having both men sitting upside down on the ceiling. In a later episode, knowledge of this is used to ambush some intruders from an unexpected direction.
252*** In the MirrorUniverse episode "[[Recap/StarTrekEnterpriseS04E18InAMirrorDarkly In A Mirror, Darkly]]", Archer defeats a [[TheDreaded Gorn]] by increasing a grav plate's power to 20 Gs, crushing it under the weight.
253* Like in the original book series, ''Series/TheExpanse'' notably doesn't have artificial gravity. When the ship is not accelerating, characters usually have their magnetic boots turned on. WireFu is used to simulate weightlessness when it's required.
254[[/folder]]
255
256[[folder:Pinball]]
257* The MadScientistLaboratory in ''Pinball/StrangeScience'' includes an Anti-Gravity machine that sends pinballs to the top of the playfield.
258[[/folder]]
259
260[[folder:Tabletop Games]]
261* The ''TabletopGame/JovianChronicles'' RPG series, which draws inspiration from Gundam is set in a future where humans have colonized the inner planets, the asteroid belt and jupiter, but space stations need a 'ring' section to rotate for habitation, and most larger vessels have a habitation arm that spins to do the same.
262* ''TabletopGame/DungeonsAndDragons''
263** ''TabletopGame/{{Spelljammer}}'' setting. Because of the [[RuleOfCool nature of physics in the D&D universe]], ships in space automatically generate enough gravity to keep objects from drifting away from them, and a "gravity plane" keeps the direction of gravity steadily "down" from the crew's perspective.
264** 1st Edition module S3 ''Expedition to the Barrier Peaks''. The starship has multiple examples of gravity control technology, including the drop chutes/tubes, inside the control room and the worker robots.
265** From the ''Planar Handbook'' comes the spell [[https://dnd.arkalseif.info/spells/planar-handbook--79/false-gravity--2202/ False Gravity]], which allows the caster to ''choose'' which way is "down". You can also fly by changing which way is "down" mid-flight, essentially [[Literature/TheHitchhikersGuideToTheGalaxy throwing yourself at the ground and missing.]]
266* ''TabletopGame/{{Traveller}}''. Space ships have "grav plates" that generate a 1G floor field, and robots can fly while on the surface of planets using an antigravity device.
267* ''[[TabletopGame/{{GURPS}} GURPS: Ultratech]]'' has a lot of technology based on gravity control. Ranging from shipboard gravity plates to grav guns to gravitic screwdrivers. There's even gravity controlling cloth that lets you fly like a superhero.
268* ''Starblazer Adventures'', based on the 1970's-80's British science fiction ComicBook. Robots could fly using built-in anti-grav units.
269* ''TabletopGame/EclipsePhase'' only has spinning habitats and ships, though since basic biomods provide immunity to the degenerative effects of microgravity many don't bother.
270* Despite the abundance of softer sci-fi elements, such as HumongousMecha, in ''TabletopGame/{{BattleTech}}'', this trope is handled pretty realistically with spacecraft. [=JumpShips=] have a centrifugal section with gravity, while [=DropShips=] generate inertial gravity through thrust.
271* ''TabletopGame/MageTheAscension'' gives us the Sons of Ether, whose ships have artificial gravity by virtue of the ethernauts that built or are flying the craft not thinking the floaty bits of space were worth the effort of putting into the local consensus reality. Tends to be relatively forgivable since they also get away with things like open decks or building their spaceship from a wooden Junk complete with somehow-functional sails... physics has much bigger things to complain about.
272* Gravity in ''TabletopGame/RocketAge'' is something of an odd beast since the setting attempts to emulate Buck Rogers, John Carter and Flash Gordon. In general artificial gravity works in one of two ways:
273** The general explanation of how gravity on Earthling [[RetroRocket rocket ships]] works is that the thrust of the ship's engines creates enough acceleration to create gravity. However, the fact that the gravity may vary with the ship's acceleration is never touched on. The [[WordOfGod official]] [[ShrugOfGod line]] is that gravity only really matters when it would be dramatic or interesting for it to do so.
274** Rocket Age's most advance race, the Europans, seem to have true artificial gravity by dint of the fact that their [[FlyingSaucer ships]] can actively ignore its effects, along with other things such as inertia.
275* ''TabletopGame/Warhammer40000'': Not only is ArtificialGravity standard equipment on ships, one of the weirder effects of space hulks (conglomerates of derelict ships that meld together in the Warp, sometimes re-entering realspace) is that when moving from one section to another, "down" might change depending on which generator is closer. One ''Literature/CiaphasCain'' novel even mentions a null-grav room for zero-G training located on a planet's surface.
276[[/folder]]
277
278[[folder:Video Games]]
279* The ''Vigilance'' orbital platform and the freighter in the ''VideoGame/{{Crusader}}'' series of games have artificial gravity, which probably made programming the game's engine a lot easier.
280* Inverted in FirstPersonShooter ''VideoGame/{{Crysis}}'': Aliens that presumably live in a zero-gravity environment use a spaceship that creates just that. The main character moves around using thrusters.
281* ''Franchise/DeadSpace'':
282** It appears that all ships, from tiny repair shuttles to massive planet-cracking mining ships have artificial gravity. However, in the first ''VideoGame/DeadSpace1'', certain areas of the ''Ishimura'' (such as the place giant rocks are broken down to extract minerals), don't, and the artificial gravity onboard is failing in other areas due to the whole [[ZombieApocalypse Necromorph infestation]] thing going on. In fact, actions in Zero-G are a fairly major gameplay element (Isaac's maintenance suit has magnetic boots, so he doesn't float).
283** The series also features artificial introduced microgravity, allowing the player to float around on the surface of various planets.
284* Half-explained in the ''Franchise/{{Halo}}'' universe. Most early human ships had no artificial gravity and the few that did achieved this through centrifugal force. However, once the UNSC started salvaging destroyed [[ScaryDogmaticAliens Covenant ships]], the existence of artificial gravity is {{Hand Wave}}d as AppliedPhlebotinum.
285** ''Literature/HaloTheFallOfReach'' had the ''Pillar of Autumn'' generate gravity via centrifugal force; in the games, it's generated by Phlebotinum instead. Worth noting that the book was written before the [[VideoGame/HaloCombatEvolved first game]] even came out; it's only one of several details that have been retconned over the years.
286** The Covenant make much more extensive use of gravity technology; all of their vehicles use anti-gravity to move and stay afloat, and they even use it for things as small and mundane as jetpacks, chairs and lifts. They even have small gravity generators attached to their aptly-named Gravity Hammers to strengthen each blow. The [[{{Precursors}} Forerunners]] they reverse-engineered the technology from had even greater mastery over it, allowing them to keep entire skyscrapers afloat for 100,000+ years with little to no outside maintenance. Forerunner Monitor [=AIs=] even have limited telekinetic abilities, [[spoiler:while the Ur-Didact's own pseudo-telekinesis is so powerful that he can easily beat the Master Chief without ever touching or shooting him]].
287* ''Franchise/MassEffect'' inverted the breaking part in the game's Codex. As soon as a ship goes into combat it turns off all gravity to decrease heat buildup and to divert power to systems that need it more. The ship's interior are marked and color-coded to help right the disorientated passengers.
288** In addition, only the existence and use of [[MinovskyPhysics mass effect]] allows ships to have artificial gravity that doesn't rely on movement. Those that don't use mass effect use methods such as rotation.
289*** Ships not designed to land in atmosphere - for example, cruisers and dreadnoughts - also have their decks oriented with the "floor" toward the engines, so that the thrust will provide artificial gravity while moving.
290** Most biotics powers are based on control of artificial gravity. Throw is a directed burst of gravity that grabs someone and throws them away from the biotic by creating a powerful gravitational pull behind them. Lift/Pull grabs an opponent in a zero gravity field that pulls them into the air. Warp creates powerful, distorted gravity fields around the target that pulls apart their armor and tears up flesh and muscle. Singularity creates an intense high-gravity zone that draws all objects around it into the area of effect.
291* The FirstPersonShooter ''VideoGame/Prey2006'' is pretty creative with this, in that the Sphere's artificial gravity goes in different directions in different parts of the ship. You can look out a window in one room and see people running on the ceiling in the next.
292* ''Franchise/SonicTheHedgehog'' is known for its space levels that actually ''reverse'' the gravity, making you walk on the ceiling, or, in the case of [[GimmickLevel Crazy Gadget]], the walls.
293* Used to good effect in ''VideoGame/UnrealIITheAwakening'' where the artificial gravity starts failing, allowing the player to make larger leaps than normal, it then starts playing up even more pulling the player against the walls instead of the floor.
294* ''VideoGame/SuperMarioGalaxy'' (and its sequel) have several dozen tricks with artificial gravity, changing gravity, and inertia puzzles -- often several times in the same level.
295* Gravity manipulation in the ''VideoGame/SpaceEmpires'' series takes many forms, from ships, to preventing [[EarthShatteringKaboom pesky planet killing weapons]], to creating {{DysonSphere}}s if your tech level is high enough.
296* In ''Platform/{{Roblox}}'', most games that are in space have this, since they're essentially the same as non-space games but with a different SkyBox. Some games actually do set their gravity value to zero in order to implement more realistic zero-gee movement systems.
297* Several stages in the ''VideoGame/MegaManClassic'' series have this, as they take place in space, but have Mega Man maneuvering normally, albeit sometimes with underwater-style JumpPhysics. Some stages also have gravity changing panels, and there are several weapons that reverse gravity ([[VideoGame/MegaMan5 Gravity Hold]]) or create artificial gravity wells ([[VideoGame/MegaMan9 Black Hole Bomb]]).
298* ''VideoGame/SepterraCore'' presents The Doomsday Weapon which works by creating a gravitational disturbance which causes the target continent to rise up out of its World Shell and crash into the underside of the shell above. [[spoiler: This turns out to be a massive Chekhov's Gun: by raising the proper continents to the upper shells, they form a rune pattern which grants Septerra access to the Kingdom of Heaven.]]
299* ''VideoGame/NexusTheJupiterIncident'' has the spinning kind and the more traditional artificial graivity field, although none of that is mentioned. The only indication that all but Earth ships (which have spinning sections and very limited maneuverability) have AG is their lack of spinning sections and increased maneuverability and acceleration (suggesting InertialDampening).
300* In ''VideoGame/StarCraft'' Terran ships and space platforms use "gravity channeling", in the latter case it explains how ground units can walk around on those things without flying off into space.
301* VideoGame/{{Startopia}} has a rotating space station creating CentrifugalGravity.
302* In ''VideoGame/ShoresOfHazeron'', special technology is needed to give a ship or a building artificial gravity. With it, you can give your gravity fields whatever size, shape and direction you like. Can be abused for fun and profit, often to the dismay of boarding parties. You can also tie the field to a door switch, producing complex and possibly deadly interactions.
303* ''VideoGame/SidMeiersAlphaCentauri'' has the technologies "Graviton Theory" and "Graviton Mechanics" (one of which reads a [[EncyclopediaExposita Datalinks]] quote going "What goes up...had better darn well stay up."). They allow you to build Graviton Struts (making land units faster) and "Gravships" (an air unit that, based on their appearance, seem to be propelled by fans and lifted by anti-gravity; that is to say, basically [[ZeppelinsFromAnotherWorld dirigibles]] with antigravity replacing lifting gas).
304* Shay's space-ship in ''VideoGame/BrokenAge'' obviously has artificial gravity to allow him to walk around. He does go on several space walks but his kept firmly on the hull by magnetic boots; at one point he does manage to fly around space using whipped-cream as a propellant. [[spoiler: This is impressive as we later learn that Shay hasn't been in space all this time and it is in fact the weightlessness that is being faked.]]
305* ''VideoGame/SpaceEngineers'' has this in spades, with constructable Gravity Generators that choose a "down" direction based on which way they are oriented. You can also change the strength of the field, as well as its X, Y, and Z dimensions, allowing for specific shapes and cool tricks like walking around the inside perimeter of a structure. The effects of multiple generators also stack, allowing gravity to be ''weaponized''; dropping an object with a lot of mass into a powerful gravity field will launch it with incredible force, and do massive damage to whatever it hits.
306* Your ship in ''VideoGame/{{Rodina}}'' has a field of gravity even when on different planets. When you enter your ship from a planet or asteroid with a different intensity and direction of gravity, there is a notable shift between the outside and inside.
307* ''VideoGame/Prey2017'' has artifical gravity over most of the space station with navigating in microgravity as significant gameplay element, weather it's flying around outside the space station or navigating the '''G'''ravity '''U'''tility '''T'''unnel '''S'''ystem.
308* All ships in ''VideoGame/GalaxyAngel'' and ''VideoGame/GalaxyAngelII'' seem to be equipped with artificial gravity, which is HandWaved due to them being LostTechnology. One incident in the first game has Tact and Ranpha temporarily deactivating it in the Elsior's storage room to move some heavy containers, but they lose control while floating and end up [[AccidentalKiss kissing each other by accident]].

311[[folder:Webcomics]]
312* The ships in ''Webcomic/AlienDice'' operate with artificial gravity.
313* In ''Webcomic/CrimsonDark'' the ''Niobe'' has grav-nets that maintain a charge for hours after power is cut, but are a pain to modify or replace. Newer ships and stations have variable grav-plates that can be altered [[https://www.davidcsimon.com/crimsondark/index.php?view=comic&strip_id=394 remotely]].
314* In ''Webcomic/{{Freefall}}'', the satellite delivery story arc goes out of its way to demonstrate the lack of artificial gravity. WordOfGod discusses the various nods of clothing and gear to the lack of a convenient gravity quite a way down [[https://web.archive.org/web/20130222045719/http://home.comcast.net/~ccdesan/Freefall/Freefall_Backstory.html#Flo-Details this page]] (almost right before the details section for Sam Starfall).
315* Much of the [[TheFederation Nemesites']] and [[OurDragonsAreDifferent dragons']] technology in ''Webcomic/TheInexplicableAdventuresOfBob'' seems to be based on gravity manipulation.
316** Galatea claims a ship's artificial gravity, and all related systems (the ability to make a ship hover, etc.), run off a separate power source than everything else on the ship; a footnote then says that this is why, "as all space opera fans know, the artificial gravity never, ever goes out!"
317* ''Webcomic/SchlockMercenary'' has a rare and interesting variation; artificial gravity is impossible. What they actually have is gravity ''manipulation'' or "gravitics", which is as well-developed as electronics. Those big round spheres every ship has are [[http://en.wikipedia.org/wiki/Neutronium neutronium]], which acts as a source of gravity to manipulate. Also explores the concept of '''weaponized gravity''': 'Gravy guns' are extremely powerful, short-ranged weaponry that, well, uses gravy to make gravy (or compressed neutronium, or just fine shreds of atomic matter) out of anything it's aimed at.
318** The "Mallcop Command" storyline is set on a space station that uses rotation to generate its gravity; it's a historically preserved artifact of mankind's early space exploration after cheap gravitics became available.
319* In ''Webcomic/SluggyFreelance'', Bun-Bun actually [[http://sluggy.com/comics/archives/daily/20010723 weaponizes a ship's artificial gravity]] to make everyone inside fall "up" towards the ceiling, then fall back down to the floor, repeating as necessary.
320** The same technique is used in one ''Webcomic/QuantumVibe'' strip, with bloody consequences.
321* In Christopher Baldwin's ''Webcomic/{{Spacetrawler}}'', gravity on space-ships is generated by collecting actual mass (space debris, on-board refuse... [[http://spacetrawler.com/2010/03/10/spacetrawler-22/ criminal evidence]], etc.) and compacting it using the titular spacetrawler, an incomprehensibly advanced piece of AppliedPhlebotinum (which is also used to manufacture supplies and fuel the engine).
322* In ''Webcomic/UmlautHouse'' anti-gravity is accomplished via spinning tops with very fine control circuitry. [[http://maskedretriever.com/uh2/d/20060103.html Seriously]].
323[[/folder]]
324
325[[folder:Web Original]]
326* ''Website/SCPFoundation'', [[http://www.scp-wiki.net/scp-2099 SCP-2099 ("Brain in a Jar")]]. One of SCP-2099's inventions is a generator that doubles the force of gravity on all nearby objects. It was originally an AntiGravity generator, but he changed it by crossing out the word "Anti" that was written on it.
327* In TabletopGame/NewVindicators, [[IJustWantToBeSpecial Alex Winters]] is the son of a superhuman, and the only one of his brothers to not develop his powers. Dejected, Alex is eventually given a belt that simulates incredible gravity, which he trains with. Eventually, he becomes one of the best martial artists in the world, and [[WordOfGod officially]] the most agile human being (without super powers), able to fight a lot of superhumans with his skill and a few martial arts weapons and have a fair chance of victory.
328* In the [[Website/ThingsOfInterest Ed stories]], Ed decides that true artificial gravity is impossible. However, the Andromedans are able to create quite a good facsimile of gravity through very precise use of their Momentum Cannon, by repeatedly applying a downward thrust to all objects on board the ship, so as to simulate gravitational acceleration.
329* In ''WebAnimation/MonkeyWrench'', artificial gravity, or [=AG=], is a common but expensive feature of starships and space stations. Shrike and Beebz can't afford to install it on their ship, forcing them to wear magnetized boots when walking around and strap themselves to the bed with duct tape when they want to sleep.
330* A realistic example in ''Literature/JunctionPoint''. The starship ''Odysseus'' is able to accelerate at 1g, which simulates gravity via thrust. However, when orbiting a planet, it turns its engines off, and everything becomes weightless again.
331* In the ''WebAnimation/RedVsBlue'' universe, you'd expect there to be artificial gravity. It gets special mention because there's a few fight scenes in zero gravity that are [[Awesome/RedVsBlue amazing]].
332* Literature/WhateleyUniverse: in "Tennyo's Easter", while Tennyo is off-world, we see spacecraft with artificial gravity, but she has a ship that doesn't need it because she ignores gravity and flies.
333* Photon shells in ''Literature/{{Phaeton}}'', as well as enabling FTL travel, also reduce G forces and generate unidirectional gravity. It is also near impossible to fail, but can very easily be switched off.
334[[/folder]]
335
336[[folder:Western Animation]]
337* In ''WesternAnimation/ThreeTwoOnePenguins'', even though it's never explicitly stated whether the Rockhopper has it, the characters not floating around in it is evidence enough of its existence.
338* The very first episode of ''WesternAnimation/ExoSquad'' was partly aboard a cargo ship that had been attacked by pirates, and was without gravity. Or so they said, anyway. The animators apparently couldn't make up their minds about whether they were moving in or out of a gravity field. Otherwise, though, they have artificial gravity, and can even use it as a weapon for defending planets (GRAF [[=GRAvitational Focus=]] shields, the focus of the Venus story arc).
339* ''WesternAnimation/{{Futurama}}'' - played straight, as "Gravity Pumps" have been invented. There's even a scene where Bender is flying [[strike:drunk]] sober upside down on a planet, and everything inside is still "pulled to the floor" just like normal.
340** Also, in the episode "Brannigan Begin Again", the crew is delivering pillows to a world with significantly higher g than earth. Even after they land on the planet, they are unaffected until they step off the platform that lowered them to the surface. At this point the cart used to move the pillows is destroyed by the weight, Fry's normally upright hair falls, Bender's legs collapse, and Brannigan's girdle fails spectacularly.
341** In another instance, the crew are working out in a gym, and Fry is bench-pressing an impressive number of plates. Then Leela notices that someone has "turned the gravity down" and adjusts a dial on the wall, causing the weights to immediately fall and crush him. [[FridgeLogic It's apparently a very localized effect, as the gravity alterations didn't seem to affect anyone else]].
342* In ''WesternAnimation/JusticeLeague Unlimited'', Mr. Terrific switches off the Watchtower's artificial gravity and then switches it back on again to incapacitate Lex Luthor, who's in Flash's body at the time.
343* Both used and not used in ''WesternAnimation/KimPossible'': a space station in one episode had artificial gravity, which was turned off during a fight. A quick scene in space didn't have gravity, but the aliens' ship in the fourth season did.
344* ''WesternAnimation/TheRenAndStimpyShow'' - in "Space Madness", Stimpy has Ren take a hot bath to sooth his nerves...he also shuts off the gravity (with a light switch) to help. It only affects Ren and his bath water.
345* In one multi-part episode of ''WesternAnimation/RockyAndBullwinkle'', they encounter a substance called Upsidaisium, which has negative weight.
346* ''WesternAnimation/RoughnecksStarshipTroopersChronicles'' had the main characters floating realistically the first time they were shown on the spaceship ''Valley Forge''; for some reason, probably animation difficulties, they never showed it again.
347* ''WesternAnimation/SpacedOut'': The Krach Industries space dome, which houses an Earth-like town, has artificial gravity that can be switched on or off at any time.
348* ''WesternAnimation/StarTrekTheAnimatedSeries'':
349** In "The Practical Joker", the title character uses its control over the Enterprise computer to turn off the ship's artificial gravity system, causing the characters to float around in zero gravity.
350** In "The Jihad" the BigBad creates a zero-gravity area inside the building so his opponents can fight him in the air.
351* In ''WesternAnimation/StarTrekLowerDecks'', it's played depressingly straight, to the point that a starship with ''literally no other functioning electronics'' still has gravity.
352* ''WesternAnimation/StarWarsResistance'': [[Recap/StarWarsResistanceS2E1IntoTheUnknown "Into the Unknown"]] has Kaz, Torra, Neeku and CB-23 having to fix [[spoiler:the Colossus']] artificial gravity after it conks out, due to the gravity generator not having been needed for over 20 years. They have some initial difficulty that results in the gravity switching between nothing and ''too'' heavy, resulting in people having a drunken celebration getting smashed to the floor.
353* ''Franchise/{{Transformers}}'' are somewhat implied to have such a device with this principle; what with being heavily armed, 30 foot tall robots. Many of which can even fly.
354[[/folder]]
355
356[[folder:Real Life]]
357* Astronauts that went aboard the once-functioning Skylab satellite wore magnetic shoes during work so they could have a simulated feeling of gravity while doing tasks that zero g would make complicated, but since the Skylab was decommissioned this technique has never been replicated.
358* According to general relativity, it might be possible to induce, through Einstein's general relativity, a spacetime metric that allows for gravity inside a bounded volume, with little effect outside. Evidence points, however, to it taking a ludicrously large amount of negative energy (similar to the quantities required for [[FasterThanLightTravel wormholes and warp drives]], which is several ''Jupiter masses'' for most useful purposes). Fortunately there's actually some wiggle room to [[HandWave wave your hands in]], since the particulars of the relations between gravity and quantum theory are not perfectly understood. A writer can simply say "[[MinovskyPhysics figuring out how M/Superstring/Hologram/The-Turtles-That-Go-All-The-Way-Down Theory worked, revealed an easier way to get artificial gravity (and warp, since they're related)]]". We can, however, in a trivial sense, perfectly simulate Earth's gravity with as little as one Earth mass... just look at [[ShapedLikeItself Earth]]. This also means that smaller, denser things could have the same gravitational pull as Earth. Compared to the alternative, this is actually more plausible at this time.
359* A section of the [[SpaceStation ISS]] was planned which would have been able to generate artificial gravity between 0.01 and 2 times that of Earth gravity via [[CentrifugalGravity spinning]], but was eventually cancelled. The module is currently on display in Japan.
360* Some hypothetical designs for interplanetary vessels would use steady acceleration to simulate gravity. Such vessels would rotate 180 degrees halfway through their journey, flipping the engines to decelerate and the floors to correspond with simulated "down".
361** This also has the advantage of allowing relatively rapid interplanetary travel, taking only days or maybe weeks (if you're traveling out to Pluto or someplace really far), instead of years as it does now. The downside is that the power output from the engine would be gargantuan (meaning that if the engine has any sort of heat leakage, it will likely vaporize from the sheer heat). Real-life engines are generally either high-thrust/low-exhaust-velocity (like the Space Shuttle) or low-thrust/high-exhaust-velocity (like with ion drives). Such a ship would need to be high-thrust (in order for there to be a decent sense of acceleration), ''and'' high-exhaust-velocity (in order to ''get'' to such high speeds. Accelerating at 1 ''g'' for a week equals out to about six thousand kilometers per ''second'').
362* Heim theory supports that a rotating magnetic field created by a ring spinning around a superconducting coil would produce an artificial or anti-gravity field. It is, however, also fringe science and fairly unlikely to hold water.
363* Many space station concepts during the 20th century commonly used a ring-shaped station with the center in microgravity while the outer rim spun constantly to generate artificial gravity through [[CentrifugalGravity centrifugal force]]. ''Film/TwoThousandOneASpaceOdyssey'' made the concept even more popular.
364* You can create gravity, but not in a useful way since the effect is 15 orders of magnitude less than 1 g for reasonable velocities, by increasing the spin of a massive object in a similar manner as you can generate an electric field by increasing the power of a magnet. Once the spin stops increasing, the gravity goes away. It does still have a [[http://en.wikipedia.org/wiki/Gravitoelectromagnetism gravitomagnetic]] field that will affect objects moving past quickly, just like a magnet will alter the direction of an electron beam.
