Time Travel

Time Travel is the theoretical ability to travel through time at will. It is widely regarded by the scientific community as impossible but is still believed by some people to not only be possible but to have already happened.

In Fiction
Time travel has been a frequent focus in many works of fiction, including comics, manga, books, cartoons, anime, live television shows, short films, movies, and video games. Many of these works only use time travel to a small extent, be it in a single episode or just for a joke, but others have had their main story relying entirely on this concept.
