Theme: Alternate Timelines and Multiverses

Alternate Timelines concerns itself with alternate possibilities of how the present may have transpired. These differ from Alternate History Films, which are concerned itself with alternate outcomes of historical events. Alternate Timelines take place on a personal level and tell how the events of an individual’s life may have transpired differently had a crucial event been changed or they made a different decision at some point in the past.

There are also various stories that show individual pasts changed as a result of time travel. Also popular particularly on tv have been Mirror Universe stories that show dark and very different versions of familiar characters.

In the 2020s, the Multiverse idea has gained a good deal of traction – for effective purposes, the multiverse is no more than an Alternate Timeline that is regarded as a physical place and the universe is regarded as having an infinitely possible number of such timelines.
