** And then the author {{RetCon}}s this in the ''Earth Afire'' 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.

** In fact ''Literature/HaloTheFallOfReach'' has the ''Pillar of Autumn'' generate gravity via centrifugal force. In-game, it's generated by Phlebotinum. Worth noting that the book was written before the first game even came out; it's only one of several details that have been retconned over the years.
** 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 took the technology from had even great mastery over it, allowing them to keep entire skyscrapers afloat for 100,000+ years with little to no outside maintenance. 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]].

* The invention of artificial gravity helps to drive the plot of Creator/LoisMcMasterBujold's ''[[Literature/VorkosiganSaga 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.

In 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. This makes a certain degree of sense, as fixing a ship while floating around helplessly would probably take much longer. 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.

This makes a certain degree of sense, as fixing a ship while floating around helplessly would probably take much longer. It also makes sense energetically, as there is no (1st Law) reason for an artificial gravity system to consume a significant amount of energy.

Added DiffLines:

* 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.

* 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.

*** Incorrect. It also happened (briefly) in an episode of ''Series/StarTrekEnterprise''. A cloaked alien ship was "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 was that the aliens were too shy to just contact them and ask for help. The presence of the ship in the Enterprise's wake caused warp field distortions that fed back into other systems and caused malfunctions throughout the ship (the computers and crew didn't know to compensate for a ship being there because they didn't know it was). 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.

* 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.

* The discovery of a way to reduce gravity drives the plot of Creator/HarryHarrison's ''The Daleth Effect''. The discoverer 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]].

* The FirstPersonShooter ''VideoGame/{{Prey}}'' is pretty creative with this, in that the Sphere's ArtificialGravity 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.
