They've found some more astronomical calculations by the Mayans, which were the basis for the Mayan Calendar. Apparently, these calculations predict the position of the moon to years way past the current projected end of the world this year.
I'm thinking they would have been farther along if they had Excel, an H.P. printer and a calender program to print their results. Then again, all of that would have been useless without a wall plug and some electricity.
