  • How to defend Earth from asteroids???

    Simple. Why not use the 40,000 NUCLEAR weapons we have at our disposal!

  • such great minds work at NASA.I wish I was in their offices and labs for one day to see how they work and explore our universe

  • Build a few HAARP satellites that orbits Earth. Then blast the shit out of that asteroid. Yup, that should kill it. HAARP is Tesla technology that he split the patents up as he gave each of the world's super powers pieces of the patents. Tesla did not want give the complete patent to any one country because he says that it is a technology that can literally crack the Earth. Well, go HAARP!

  • We could redirect it to hit planets that we don't like. Like Mercury. Fuck Mercury!

  • Bring that thing down into earth and mine it..Metal prices will go down..

  • The "if" in "if we detect them" if quite a big one.

  • So the asteroid ain't gonna hit us ?

  • @Seannyskillz I'm sorry this was too sophisticated for you. Go watch Austin Powers if you want "Lasers."

  • @batbawls I bet it was PETA: People for the Ethical Treatment of Asteroids.

    (Sorry I couldn't resist...:)
