Thank you for doing this because I couldn't wrap my head around the explanation for the "Star Trek" reboots. I was actually a bit worried because it made me think of "Donnie Darko" and that did not end well for Donnie.
Yes, but the problem is that in the world of Star Trek, changing the past doesn't lead to an alternate reality. Every change in the past, changes the future of the same reality (see: The city on the edge of forever (TOS), First contact (TNG), Year of Hell (VOY) and many others....)
To be fair, 99% of Star Trek's nefarious time travel episodes always end up "closing" the loop by convenient solutions at the end of the story arc. This case is different because the only way they could close this particular loop is prevent the black hole from ever opening in the first place.
