I would probably become a theif and steal everything i could and enjoy it and just before whatever happend, i'd have jacked a space shuttle with enough supplies for a few months or so and take off (Of course it would be the latest one so it would have hypersleep so i sleep the whole flight or at least die in my sleep)
And laugh how stupid some people were not to join me when i offered them a chance to live. Of course i'd email everybody except the jerks on this fourm and bring them with me along with my family and friends. (The ship would be big enough to hold everyone)
So....Well maybe i'd try to blow up the asteroid by planting a bomb on the satalite I brought and detonating when it touched it.
Well what do you think?
PS This is in the future of course. If not, well i'll just pray to God and have the best day of my life.
