Whoa. I done some research on this 2012 stuff, and found some Awesome stuff. I shall share:

On July 31st, 2006, An amazing thing happened on the sun. A reverse polarity sun spot, which is indicative of the next solar max cycle, number twenty four. That cycle is where the sun goes into its maximum emissions activity. The peak of the increased suns activity will occur in 2012.

This also corresponds to the Maya 'end of the world' prophesy.

The Mayan calendar, or so I've heard, is three gears.
The hieroglyphs on the larger wheel mark the three hundred and sixty five days of the solar year. Those on the two smaller gears mark the two hundred and sixty two days of the priests sacred calendar. Using this calendar, Maya priests predicted the exact time and place of solar eclipses. The accuracy of Maya astronomy still astounds. The cycles of the moon, where mapped so precisely, that today, fifteen hundred years later, their calculations are off by only thirty-three seconds.

By the Maya calendar, the world will end on Sunday, December the 23rd, 2012.
