as concern your question there are three basic things which said World end in 2012.
1. Earth Beats: is the sound between plate of earths. now it reaches to 12Hz if it go on 13Hz Then Earth will stop moving and start moving to opposite direction. and cause to maximum earth quakes, life will not end but maximum lossed happen.
2. Nastredamas: the great Predictiation in world.
