What a complete load of crap. Couldn't they be more creative than to just adapt some physics to try to explain why they had to invalidate everything that came before? Very weak and disappointing. This flick sounds worse by the day.
I am actually working on a masters in physics, but this is not really making much sense to me. I get the whole multiverse theory. What I don't get is how these knuckle heads think they preserve canon by creating an alternate time line?
I think I'd rather see Star Trek rest in peace rather see all this crockery and silliness happen. Shame on you people.
