What will happen if the world explodes?

Answer 1

we would be dead

The question is purely a hypothetical. Even if ever the world explodes, no living objects will survive. How the state of affairs will be, has been depicted in Spielberg's film with adroitness.

Answer 2

The world will never explode. Plus, even if it will, we won't know when. Some people believe that the world will explode on December 12, 2012, but that's just nonsense. No one is stupid enough to believe that just predictions are enough to have an exact answer. For all of the people who believe the world will explode in 2012, it may not. Don't scare kids with the stupid predictions.
