Astrophysicist and scientific rock-star Neil deGrasse Tyson probably knows more about the universe than you know about anything. He's a smart dude, and now he's taking on idiots who think the world is going to end on December 21, 2012.

...before proving once again that he's a top-notch kind of astrophysicist:
Now that you've been told off by one of the smartest men in the world, do you still think the world's coming to an end? [Neil deGrasse Tyson]
