in the movie where we saw Spock come trough the wormhole ,etc, he was coming from the universe of the prime timeline, yes?
I would still like to know how no one in the galaxy knew that Romulus' star was going to go nova?
NO. He was not. JJ Abrams created the entire alternate timeline to bring it within his level of intellect. The wormhole was allegedly created by magical "red matter" which exists nowhere except in JJ Abrams' mind. Such a substance would be impossible to exist due to the laws of physics. So there should be no wormhole, let alone the time travel element of it. Second, the actor Leonard Nimoy is the only thing common between the prime timeline and the 2009 movie. That character was NOT prime timeline Spock, even though it was Leonard Nimoy. It is an illusion only. Hardcore fans see this very clearly/ The Abrams Trek is like a remora on a shark or a tick on a dog. It isn't really part of the whole, it is only attached to the whole. Like a parasite.
