I saw star trek today...
So... let us discuss some time travel theory (again). What is your opinion on this?
Let us start from a single timeline, one that is pure and without any sort of paradoxes or time travel whatsoever - timeline A.
A man from the year 2100 travels back in time to the year 1900 and only slightly changes history, creating the new timeline B. This change is grandfather paradox free - meaning that his changes do not alter history enough to stop his future self from going back and making the same changes. Okay?
So let us say that now a man from the year 2200 in timeline B travels back in time to the year 2000. He radically alters the timeline, making it very different from timeline A or B (Timeline C). In timeline C things have changed so radically that the man from the first example no longer exists and he no longer travels back in time.
So, in which timeline do the years 1900 and 2000 fall under? A, B, or C?
