Scientists at NASA's Jet Propulsion Laboratory have put out a new video to address false claims about the "Mayan apocalypse," a non-event that some people believe will bring the world to an end on Dec. 21. 

In the video, which was posted online Wednesday (Mar. 7), Don Yeomans, head of the Near-Earth Objects Program Office at NASA/JPL, explains away many of the most frequently cited doomsday scenarios.

Addressing the belief that the calendar used by the ancient Mayan civilization comes to a sudden end in December 2012, and that this will coincide with a cataclysmic, world-ending event, Yeomans said: "Their calendar does not end on December 21, 2012; it's just the end of the cycle and the beginning of a new one. It's just like on December 31, our calendar comes to an end, but a new calendar begins on January 1."

This nonsense will go the way of the Harmonic Convergence and Y2K.  Much ado about nothing.  To read more, click here.
