I've been getting rather irritated by the sheer volume of nonsense being spewed all over the Internet about the coming 'catastrophe' in 2012. The expiry of the current cycle of the Mayan 'long calendar', the existence (not!) of a mythical 'Planet X' called Nibiru, the alignment of various galactic features on December 21st of that year which will 'flip the Earth off its axis' . . . all these and more are spoken of with bated breath by those who clearly lack even the most basic scientific education.
It's all bull, folks.
If you, like me, are tired of having to answer questions from the ignorant and uninformed, there are a few good resources online to which you can direct people. NASA's Astrobiology Web site is a good start. As David Morrison of its 'Ask An Astrobiologist' column explains:
Stories about the fictional planet Nibiru and predictions of doomsday in December 2012 have blossomed on the Internet. There are now (June 2009) more than 175 books listed on Amazon.com dealing with the 2012 doomsday. As this hoax spreads, many more disaster scenarios are being suggested. “Ask an Astrobiologist” has received nearly a thousand questions about Nibiru and 2012, with more than 200 answers posted.
He provides links to some good resources, and answers the 20 most common questions. It's worth reading the whole thing.
Another good resource is Bad Astronomy's analysis of the 'Planet X' fantasy. Recommended reading.
Finally, for a light-hearted look at this nonsense, here's Dr. Neil deGrasse Tyson's take on it.
I like a scientist with a sense of humor!
