Doomsday scenarios seem to be getting more common than solar eclipses. (Remember Harold Camping, the radio minister who declared May 21, 2011, as the day the world would end -- and then revised his doomsdate to Oct. 21?) The latest prophecy comes from the ancient Mayans, who supposedly identified Dec. 21, 2012, as the day of doom. NPR's David Greene talks with David Stuart, an expert on the Mayans from the University of Texas.
"The Maya never, ever, said anything about the world ending at any time - much less, this year," says an archaeologist who helped translate the ancient culture's hieroglyphs. Still, David Stuart says, he often gets emails from people who want more details about the end of days.
