This is in sharp contrast to the Nibiru legend that thrives on the Internet where there is no shortage of end-of-world predictions.
What's more, we live in a largely science illiterate society where the pronouncements of real experts are often suspect and derided. This is obvious in the political debates over global warming, evolution, and questionable alternative medicine.
Keep in mind that if any part of the Nibiru prediction is true it would mean the history of the solar system is vastly different from what we have theorized and gathered painstakingly though telescope observations, space probes and dynamical computer models.
Astrobiology would be all wrong because a world colder than Pluto is supposedly inhabited. And, Newton's laws of gravity are all wrong too, based on the planet's alleged influence on Earth.
The Nibiru mania is the epitome of a pseudoscience: reject a huge collection of knowledge, conventional wisdom, and rational thought and come up with an ad hoc solution no matter how implausible it is.
For anyone who may think I'm being a snooty Nibiru-basher, all you need to do is post the planet's orbital ephemeris here. I'll get one of my amateur astronomer buddies to go out and photograph the region of sky where Nibiru supposedly is, and then I'll gladly publish the picture.
After all, seeing is believing.
