The Mayan civilization had one of the most advanced calendars outside of Europe or Asia. When crafting their calendar, they ended it on December 21, 2012. What's going to happen that day? Surely, most people aren't afraid, but what are some of the theories out there? National Geographic says nothing:
Houston and Stuart's initial interpretation indicated that a god will descend at the end of Bak'tun 13. What would happen next is uncertain, although the scholars suggested this might have been a prophecy of some sort.This 1996 analysis was picked up "on many New Age websites, associated forum discussions, and even a few book chapters" as evidence that the Maya calendar had predicted the end of the world, according to Stuart.Houston and Stuart, however, independently revisited the glyphs recently and concluded that the inscription may actually contain no prophetic statements about 2012 at all.Rather, the mention of the end of Bak'tun 13 is likely a forward-looking statement that refers back to the main subject of the inscription, which is the dedication of Monument 6.
