You all DO know that this is knowledge obtained by extraterresteral beings right?
See, the Mayans had this information back a long time ago. They got it from a dying martian civilization that tried to flee mars and move to earth, but ran into a tribe of people called Jehovahs Witnesses that drove them to commit mass suicide. The Mayans stole this knowledge from the martians before they died and kept it away from the Jehovahs witnesses. They just let them continue to go around banging on peoples huts passing out leaf pamplets. This knowledge is how the Mayans were able to travel through time trying to escape, and accidentally found that the world will end this year (2012). They made a calender leading all the way up to that date and then left it as a warning for everyone else so we can find it now.
The CIA had this cloaking information right about the same time they found the Mayan Calenders, ( one agent accidentally stumbled across it while looking for his toupee and a bottle of hair tonic), but didnt want anyone to know about it. Somehow it wound up in the hands of Rosie O Donnell, who chose to sell this info to wired magazine in exchange for an all expense paid trip to weight watchers.... and that's how this information became avaliable to everyone.
See...I've been doing my homework
