2012: Six end-of-the-world myths debunked

From an article by Brian Handwerk for National Geographic News:

The end of the world is near—December 21, 2012, to be exact—according to theories based on a purported ancient Maya prediction and fanned by the marketing machine behind the soon-to-be-released 2012 movie.

But could humankind really meet its end in 2012—drowned in apocalyptic floods, walloped by a secret planet, seared by an angry sun, or thrown overboard by speeding continents?

And did the ancient Maya—whose empire peaked between A.D. 250 and 900 in what is now Mexico and Central America—really predict the end of the world in 2012?

At least one aspect of the 2012, end-of-the-world hype is, for some people, all too real: the fear.

NASA's Ask an Astrobiologist Web site, for example, has received thousands of questions regarding the 2012 doomsday predictions—some of them disturbing, according to David Morrison, senior scientist with the NASA Astrobiology Institute.

"A lot of [the submitters] are people who are genuinely frightened," Morrison said.

"I've had two teenagers who were considering killing themselves, because they didn't want to be around when the world ends," he said. "Two women in the last two weeks said they were contemplating killing their children and themselves so they wouldn't have to suffer through the end of the world."

Fortunately, with the help of scientists like Morrison, most of the predicted 2012 cataclysms are easily explained away.

The Maya calendar doesn't end in 2012, as some have said, and the ancients never viewed that year as the time of the end of the world, archaeologists say.

But December 21, 2012, (give or take a day) was nonetheless momentous to the Maya.

"It's the time when the largest grand cycle in the Mayan calendar—1,872,000 days or 5,125.37 years—overturns and a new cycle begins," said Anthony Aveni, a Maya expert and archaeoastronomer at Colgate University in Hamilton, New York.
