Ancient Mayan glyph adds 7,000 years to doomsday clock

On a tiny patch of six square miles of jungle floor in Guatemala, a stunningly preserved ancient Mayan glyph is changing how archaeologists think about the Mayan calendar. Excavated in 2011, the intricate artworks revealed a "lunar table," an ancient tool for calculating planetary motions, which indicates dates 7,000 years in the future -- adding further evidence that a 2012 apocalypse isn't even in ancient Mayan mythology. Yes, it's official: You need to pay down all those credit cards you've been giddily using to pay for your end-of-the-world doomsday yacht party. But if you haven't cashed in your retirement fund already, consider a trip to South America to see these stunning murals, which continue to reveal new insights into the Mayan empire.
