Honestly, I don't think it matters. You have to be able to adapt to the situation at hand. In some case you may die before you can do anything about
it. There is nothing you can do. In others you might have a fighting chance. That is when you take it and use it.
The asteroid scenario, is a particularly nasty one. Even if you survive the initial impact you got the aftermath to deal with. Unless, of coarse it is
a large one, in that case it's lights out for everyone.
I don't know why a large particle accelerator would concern you, a nuclear power plant is more dangerous then particle accelerator.
Overpopulation is a problem, but there is nothing you or I can do about it.
Personally I am a lot more concerned with human doing something stupid. Maybe I am still stuck in Cold War nuke scenario.
Those are my two cents.


Sarcasm, the rest of the stuff above is serious tho.
