Nobody knows when the world will end... The world will ends when God wants it to ends no Mayan no siencetist.. no one only God can tell us and as the bible said he will come like a thief in the night no one will know..:)
Supposedly the scientists have said so.......but they have done this stupid (I believe the sun will explode, for like forever,etc)for me Its a big maybe....its all guess work anyway there is no proof of accuracy on future catastrophic events...only in books....but If it does happen then, well we humans will have to find a way to escape.....let the world die, its becoming a useless piece of trash under our (Human) hands......its still a big maybe
No the world will not end but in the year 2012 per spiritual mystics / spiritual gurus the human race will have reached a level of spiritual enlightenment that has never been experienced and will continue to progress as never before. This means a turning point for humanity to creating a better more spiritual (closer to God) environment.
