Well it depends a lot on how you describe "The World".
By any means if you are trying to refer to a total exctinction of human race.I would certainlly disagree to that.
Why do you want the exctinction theory to become a reality soon ???
Do you know that after how much possibilities amongst millions and billions of planetary objects , it was possible for life to originate and sustain on Earth. ?? And Human Race being the most intelligent amongst them(Cats are an Exception , though).
Why...dude..why ?? WHy do you want to get all of us killed ?? I ain't that bad.
