You never know.But i do believe something big is gonna happen.I don't think that it will be THE END, the last time the end of the world was with noah's ark.I think that God sent jesus on earth because he didn't want to end the world.So there is the big possibility that at 2012 Jesus Christ is coming on earth again and he will bring paradise with him.But for the people who only spread sorrow and hate will be like hell is on earth.
