Concept

Time travel

The imagined possibility of moving among times other than the present.

Time travel appears here as a philosophical device and as a theme in stories about changing the past. The archive does not treat it as an established physical phenomenon. The Temporary Timeline Hypothesis uses it to ask what kind of history a change would have to be.
