Editing Time Travel (section)

=Examples=
* [[H. G. Wells]]' novel ''The Time Machine'' <s>is one of the first cases of time travel to ever exist</s> is ACTUALLY one of the first stories to have a controllable time machine in a modern sense of this word; before that most time travelers were transported to past and future by some supernatural shit or through lethargic sleep (only for the future). The plot is about a nameless narrator taking his time machine to a distant future in order to prove his scholarly thesis.
* [[Warhammer 40,000]]: There's been plenty of examples of time travel between the mere nature of the [[Warp]] itself distorting the flow of time, [[Necron]]s like [[Orikan the Diviner]] who can traverse time through their own arcane means (likely involving enslaved C'tan), and even the [[Ordo Chronos]], an entire branch of the [[Inquisition]] dedicated to preserving the nature of time.
* [[Star Wars]]: a very arcane aspect of the Force is the “Nexus of the Force,” a place that is particularly strong in the force. If it’s the Cosmic Force, especially anywhere that the Ones are involved, time and space are wierd. One specific nexus, the World Between Worlds, allows a force user to jump to different periods in time and alter said events. Very briefly used by Ezra Miller to rescue Ashoka from her duel with Vader, then the only known entrance to the Nexus was destroyed so that Palpatine couldn’t get his hands on it. We don’t get much more exploration on the concept other than that time paradoxes are possible and dangerous. 
* [[Star Trek]]: While it has happened a couple times throughout the series, none are quite as infamous as the fourth movie, in which the crew of the Enterprise have to travel to 1970's San Francisco to procure humpback whales for their present, where the cries of the whales can cancel out the frequency of a probe that's causing severe ecological damage to the earth and all whales have been long extinct.
* [[Homestuck]]: A comic about a reality changing video game that gives some of the players time travel powers.  Making the story even more complicated is the existence of a chat program that can send messages forward and back in time, which creates tons of confusion when two people can have conversations in reverse order from each other's perspective or even get into arguments with their own past/future self.  In this story time travel avoids paradoxes with a rule that if you change the past or fail to do something your future self already did, you end up in a doomed timeline where you and all your friends are destined to die and somebody will have to travel back in time to make sure the past and future happen the way that they already did happen.
* [[Army of Darkness]]: Pretty much baked into the premise of both the movie (hapless store clerk who's fought the nightmares of an ancient book gets thrown to medieval times) and the game that spawned from it.
* [[Doctor Who]]: Nothing further needs to be said.
