The world is supposed to end (according to the Mayan Calendar) on Friday Dec 21, 2012. Few people probably actually believe this to be a cause for concern but NASA just dropped the most "Your move, Apocalypse" video there is as they confidently release their reasons why the world DIDN'T end one full week before it's slated to happen. It's good to see NASA has nothing better to do with their time than sooth fears none of us have. Also, suck it, Mayans.
