I'm getting e-mail about this weekly and I expect the nonsense to ratchet up. This latest installment in decades of flaky astronomical apocalypse predictions is loosely based on the Mayan calendar that marks the end of a 5,126-year era. Apparently the Mayans knew something about the heavens we don't, according to numerous hot-selling 2012 doomsday books on the market. Our multi-billion dollar telescopes, space probes, and 6,000 professional astronomers somehow just can't keep up with the mystic knowledge of an ancient superstitious culture.
A hypothetical planet called Nibiru -- or Planet X -- is often the root of many doosmday scenarios. In reality no such harbinger of doom exists. ~ NASA
