Temporal singularity, otherwise known as a point of divergence, 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. It may involve technology in "hard" science fiction, or may involve anything up to or including magic as the basis of the "what if?" scenario.
Every moment in our lives is a point of divergence, and i try to capture them as a memory.
A free thinker and a seeker of truth.
