But again, if you are 'creating' an entire timeline from nothing, where does all the matter and energy need to create that timeline (an entire universe) come from? This version only works if you can overwrite the original timeline, which is not what is advocated with the NuTrek franchise.
So, in other words, branching theory only works if it's really just single-timeline theory by another name, meaning that true branching theory simply cannot work. This is starting to sound like self-fulfilling prophecy.
If time occurs everywhere all at once then past events that are dependent upon future events cannot happen if those future events don't happen.
That's why "time occurs everywhere all at once" sounds nice from a poetic standpoint but is not particularly meaningful or workable when applied to an actual plot. At the point when the Abrams timeline is originally created, it is not yet subject to the effects of hypothetical time travel from its ( as yet unknown ) future. To try to somehow make it so would constitute an untenable logical proposition, and would ultimately prevent the timeline from being in a fixed state in 2233 or any other point.
There you go. And people dissed me when I said it was complicated.
