And because you can never cram too many crazy ideas into a single Disaster Hoax, there are some people who believe Planet X is actually the mythical Nibiru, supposedly known to ancient Sumerians, which has a highly elliptical orbit and passes into our solar system every 3600 years. Earth itself, according to this crackpot theory, was created from a collision between Nibiru and some other object in the asteroid belt. Nibiru also doubles as a "spaceship" of sorts, in that an alien race supposedly traveled to Earth during one of its passes and founded the human race.

The good news is that there isn't a shred of scientific evidence for any of this. Take it fromNeil de Grasse Tyson, who punctures the myth with typical good humor in the clip below. That doesn't mean we won't thrill to the sight of a cinematic end of the world, because who doesn't love a good disaster flick now and then?

And there's definitely technology related to the blockbuster film. Sony Pictures joined forces with D-Box Technologies to show 2012 with the D-BOX motion technology in a limited number of theaters. So lucky audience members will not only watch the movie, but also experience it physically since the D-BOX technology creates realistic motion effects frame by frame, in sync with the actual film. Probably not a good option for anyone suffering from motion sickness, though.
