Timelines

'''a timeline is the natural progression of a universe from start to finish. Every universe begins with one timeline, while universes function independently from one another; an alternative timeline cannot exist unless it is created by changing previously established events. Creating a new outcome, remarkably through time travel. An alternative timeline usually rewrites the original, changing how the universe continues to unfold; but previous timelines can be revisited through extra-dimensional means. These timelines all inevitably trace back to the same universe. One universes timeline cannot affect another through typical time travel means, meaning if something where to change in “Universe A”; “Universe B” will remain the same. '''
