(Repost from last year)
The Mayans predicted that the end of the world will happen 4 years from now on Dec 21, 2012 due to a polar shift.
NASA states that there will be a massive polar shift around December 2012 and the results of that shift are unknown. The North Pole could shift to the Equator within days, weeks or hours. Tighten your seat belts.
