Renowned astrophysicist Carl Sagan once described a "baloney detection kit" — a set of tools that skeptical thinkers use to investigate any new concept. A few of the key tools include a healthy distrust of information that isn't independently verified, critically assessing an idea rather than becoming irrationally attached to it simply because it's intriguing, and a preference for simple explanations over wildly speculative ones.
The waxing obsession with the planet Nibiru , which conspiracy theorists say is a planet swinging in from the outskirts of our solar system that is going to crash into Earth and wipe out humanity in 2012 — or, in some opinions, 2011 — shows that an astonishing number of people "are watching YouTube videos and visiting slick websites with nothing in their skeptical toolkit," in the words of David Morrison, a planetary astronomer at NASA Ames Research Center and senior scientist at the NASA Astrobiology Institute.
Morrison estimates that there are 2 million websites discussing the impending Nibiru-Earth collision. He receives, on average, five email inquiries about Nibiru every day.
"At least a once a week I get a message from a young person — as young as 11 — who says they are ill and/or contemplating suicide because of the coming doomsday," Morrison told Life's Little Mysteries, a sister site to SPACE.com.
What's the origin of this mass panic about Nibiru, which astronomers say doesn't exist?
