Will the world end on December 21st 2012? Here's what one very well-known astrophysicist thinks:

"The 2012 end-of-the-world scenario is a hoax perpetrated by the scientifically illiterate on the scientifically under-informed. Earth is going to be here till the end of the solar system. The sun will die in five billion years."

-- Neil deGrasse Tyson, astrophysicist, author, and director of the Hayden Planetarium at the American Museum of Natural History, New York, NY
