This is total BS- As per the Mayan calendar, the world end on 2012- because the calendar was not complete. Xtian nuts such Ministries of Van Impe, the world will end on 2012!, Jesus comes back, all non-xtians willperish in hell, only xtains will go to planet Heaven (which is within our solar system, but hidden?).
Nothing will happen to Earth, unless we are hit by a large meteorite. But then, no one can predict when that happens.
