** A later book shows a race that has developed projected time dilation fields as a response to the race having an extremely slow metabolism compared to most other races. To them, every other being is TheFlash, so their solution is to use time dilation to slow them down to their level. They can also slow them down even more as a way to immobilize enemies. Their "time twister" ships can project a field in a spherical manner for a short distance away from the ship, which helps it survive non-direct nuclear explosions (the blast is slowed down, which means the ship is exposed to smaller amounts of deadly radiation for a longer period of time instead of a quick burst of a lot of it). The field can also be turned into a directed long-ranged version, although this limits it to a cone.

* This effect is present in ''Literature/TheLeftHandOfDarkness''; the [[TheFederation Ekumenical]] diplomats consider it a good thing, since if their mission on a particular planet fails, they can hop over to the nearest planet, then turn around and come right back and have a whole new generation of leaders with which to try again.
** In the prologue to the related novel ''Rocannon's World'', a young woman named Semley left her low-tech native planet to reclaim a family heirloom that had wound up being traded off-world. By the time she returns from a journey that was very short for her, her daughter is a grown woman. In the main story, Rocannon, who returned the necklace, meets Semley's granddaughter but has aged very little due to traveling.

** The ''Bellerophon'', Earth's earliest starship, traveled half the speed of light across the galaxy for 3000 years, but far less passed on the ship.

* [[Recap/DoctorWhoS36E11WorldEnoughAndTime The two-parts]] [[Recap/DoctorWhoS36E12TheDoctorFalls ending]] of ''Series/DoctorWho'' season 10 takes place aboard a GenerationShip slowly escaping the pull of a black hole. Because of the increased gravity near the black hole's event horizon and the length of the ship, time passes much more slowly in the ship's command center than in the lower decks. This is bad news, as said decks are now inhabited by malevolent creatures who have years to plan attacks while only days or minutes pass in the higher-level decks.[[/folder]]

This is sometimes extrapolated by science fiction authors to apply to FTL Travel as well, though this does not make much sense physically. Many writers extend this so traveling faster than light means aging backwards, but that isn't how the math says it works. The time scale factor for speeds faster than ''c'' is imaginary, not negative. If an object is travelling faster-than-light, though, that means there is always some slower-than-light frame reference that sees the object travelling backwards in time -- or possibly moving in the opposite direction, with events on the object occurring backwards.[[note]]This, contrary to popular belief, would not imply TimeTravel: an observer still exists that sees events happening in the "proper" order. Trouble is, both types of observers -- those that see our superluminal buddy going forwards and those that see him going backwards -- can simultaneously exist. And they do not agree on the relative order of events. Woe and behold, causality is thrown out the window in a much harsher way than any Grandfather Paradox ever dared attempt.[[/note]] TheOtherWiki has [[http://en.wikipedia.org/wiki/Tachyon an article]] on tachyons, theoretical objects that move faster than the speed of light, and explains how this works.

** Prior to "Unnatural Selection", the Asgard used a time dilation device to try and [[SealedEvilInACan lock away the Replicators]] in a HourInsideYearOutside "bubble." The replicators managed to reverse the device's function and play that trope straight. SG-1 had to go in and correct the problem.

* ''OrionsArm'' has relativistic space travel at speeds in excess of .9c, but it's usually requires a Transapient tech ReactionlessDrive. But it's not much of an issue because people can have essentially unlimited lifespans (average Nearbaseline lifespan is about 3000 years). Also the setting's PortalNetwork requires the two mouths of the wormhole to be towed into position at sub-relativistic speeds (~.77c).
