I've heard a lot of stuff. The Mayans and other cultures have calendars that end. Some say they didn't include leapyears, some say they did.
Also around this time there is suppose to be huge sunstorms. This would cause a lot of solar radiation, disabling some satalites. Cell phones and similar wouldn't work.
If your a Christian, the bible says, no man can tell when the end is upon us.
Several well known psychics say major alien activity is suppose to happen 2010-12. Take that for what it's worth.
A lot of people have tried to predict the end and all have this failed.
