Wrong forum to discuss this, but you are so wrong. Destruction of the Romulus is a fact and canon in the Prime universe and needs to be addressed.
Destruction of Romulus did not happen in an alternate universe. It happened in Prime and Spock prevented the expansion of the supernova, but did not undo the whole situation. I don't comment on the plausibility of the supernova. There have been a lot of not so plausible science on Star Trek.
This is the point where I
vehemently have to disagree:
Fans DON'T remember Romulus blowing up -
because it never actually happened in the movie!
Seriously, ask anyone who
is not deep into Trek literature or online games - they ALL have already forgotten that event! And there is a very simple reason for it: It happened in an alternate timeline of the movie. A future that never happened.
Nero's entire motivation in ST09 is as much based in reality as that of VOY's future Captain Braxton in "Time's End":
Sure, this events happened in
his timeline - he has a
personal reason to want revenge. But it never happened in the
main timeline - the actual timeline depicted in the movie. And especially Neros backstory is waaaay less thouhgt out than that of Cpt. Braxton was on a purely technical or logical level.
Seriously, most people that watch ST09 think it's a straight up prequel to TOS. Only few peple actually realize that it's an alternate timeline - and only for a few thing standing out, like Vulcan blowing up or Khan showing up. But the general concensus for this points is more "reboot" than actually events happening parallel to each other. And really, NO ONE outside the absolute hardest hardcore fanbase hanging out on Internet forums does actually remember the destruction of Romulus
even happened!
This is really just Kurtzman not wanting to let go of his personal creation - which I can understand, but is actually detrimental to the storyworld and the universe.
