Re: Is the "Yesterday's Enterprise" alt-timeline the REAL one?
Besides, in FC the Borg and the E aren't traveling into their own past if you go by multiverse theory. Rather, they're traveling into the past of a timeline that closely resembles their own. At the end the E jumps forward in time in that same track, but as far as the original timeline is concerned the Borg and the E disappeared into a temporal vortex and never returned.
Correct, just as there's also a timeline in which the Enterprise
never followed the Borg back in time, and Earth was assimilated in the past.
