Although I realize this is tongue-in-cheek:
"2012" is cashing in on a gamut of wild doomsday scenarios revolving around the belief that the Mayan calender purportedly ends on December 21st, 2012. The date is thought to be significant to many besides, and there are even opposing theories swirling around claiming that the world won't end, but instead shift radically.
NASA is interested in particular with Nibiru " also known as Planet X, a fabled celestial object that "2012" addresses " which some believe may collide with or pass nearby the Earth, ending life as we know it.
According to physorg.com, "NASA insisted the Mayan calendar in fact does not end on December 21, 2012, as another period begins immediately afterward. And it said there are no planetary alignments on the horizon for the next few decades."
NASA posted a FAQ guide on its site, hoping to dispel some of the claims. The real proof, the agency says, is that no credible astronomers have discovered Planet X, and would have been able to track an object like it for a decade, at least.
Q: How do NASA scientists feel about claims of pending doomsday?
A: For any claims of disaster or dramatic changes in 2012, where is the science? Where is the evidence? There is none, and for all the fictional assertions, whether they are made in books, movies, documentaries or over the Internet, we cannot change that simple fact. There is no credible evidence for any of the assertions made in support of unusual events taking place in December 2012.
Q: Does the Mayan calendar end in December 2012?
A: Just as the calendar you have on your kitchen wall does not cease to exist after December 31, the Mayan calendar does not cease to exist on December 21, 2012. This date is the end of the Mayan long-count period but then -- just as your calendar begins again on January 1 -- another long-count period begins for the Mayan calendar.
So there you have it. Is NASA laying down the law, or is it all just some big cover up? Either way, we'll find out in 2012, just like we found out what was what back during y2k and also in 2003, when Planet X was originally supposed to mess us up.

As far as the "alignment to cause our sun to eclipse the center of the Universe:
I'm planning on seeing a movie with John Cusack explaining why nothing happened and pop another big bag of popcorn.
