This has probably been said before, but I don't feel like reading the entire thread. The Mayan's never predicted the world would end in 2012. That's when (a part of) their calendar ends. It consists out of 26,000 years divided over 5 periods of 5200 years. I don't know which one of the two is ending though, might be the entire period of 26,000 years or just one of the 5 smaller periods.
