Temporal singularity, otherwise known as a point of divergence, is a concept in speculative fiction, usually an item or event triggered by an item that results in divergent narratives in which the singularity alters the new timeline away from a prior "default" state, leaving behind a parallel universe in which the singularity did not occur; this is the basis of much of the "alternate history" genre and may involve technology in "hard" science fiction or may involve anything including magic as the basis of the "what if?" scenario
