'however i have plenty'
I don't know if this has been raised already but the Mayans were a race that were wiped out a long time ago by the Spanish Conquistadors. But some documents that were not burned by the Conquistadors were discovered, including a calender. This, and all other Mayan calendars found all ended at 21/12/2012.
There have been many theories from some rather ridiculous alien invasion stories to a more credible space phenomena. This space phenomena is described as an electro-magnetic wave that will wipe out our technology system and send the civilized world (Barely!) descending into the chaos of a new dark age.
I don't know if this is of any interest to anyone but it is just me saying, there are more possibilities than a giant comet to rival the leviathan of space that wiped out the Dinosaurs.
