alternate timelines

Alternate timelines are hypothetical versions of reality that branch off from a common starting point due to different choices or events. Imagine a single story that divides into multiple variations, each unfolding differently based on different decisions or circumstances. In this concept, every possible outcome exists in its own separate timeline, like parallel branches on a tree. While science fiction often explores this idea, it remains a theoretical framework for understanding how different choices could lead to diverse versions of history or the future without implying these timelines are physically interacting.
