<edit>
Actually, the 12/21/2012 date isn't the Mayan Date... The Mayan date is 12/23/2012.
The 12/21/12 is this:
Dec 21, 2012 - Terence McKenna combines Mayan chronology with a New Age pseudoscience called Novelty Theory to conclude that the collision an asteroid or some "trans-dimensional object" with the Earth, or alien contact, or a solar explosion, or the transformation of the Milky Way into a quasar, or some other "ultranovel" event will occur on this day. Anyway, something is supposed to happen, and he has lots of pseudoscientific gobbledygook to back up his thesis.
Another 2012 prediction is:
2012 - James T. Harmon's Rapture prediction #3. (Oropeza p.89)
</edit>
There are MANY retarded theories ranging from the Sun will throw out intense radiation and fry the earth to the return of "Planet X" and the aliens that 'seeded' us on earth so that they could harvest us for slaves to "Mine gold in the asteroid belt".
I SWEAR that I am not making any of that up...
I have collected a number of articles and videos on each of the various 'theories'.
I hope these help...

Ƹ̵̡Ǫ̵́ÌÆ· The End Is Coming in '2012'?
http://movies.yahoo.com/feature/2012-roland-emmerich.html
Few people have destroyed the world more than Roland Emmerich. In his mega-hit "Independence Day," aliens laid waste to pretty much every metropolitan center on the planet, and in his eco-thriller "The Day After Tomorrow," much of the northern hemisphere finds itself buried under ice. In his third crack at presenting the apocalypse, this fall's "2012," Emmerich taps into the angst of thousands of astrologers, doomsday enthusiasts, and conspiracy theorists who fear that a massive cataclysm will strike the earth on December 21 of that year. Yet unlike previous dates tied to the Earth's expiration, this one has its roots in various sources throughout history including interpretations of the Mayan calendar, astrology, and the ancient Chinese fortune-telling text the "I-Ching."

Ƹ̵̡Ǫ̵́ÌÆ· The Psychology of 'Knowing'
http://www.livescience.com/culture/090319-bad-movie-knowing.html
Though the plot is fictional, this scenario has occurred many times in the real world. In 1997 Michael Drosnin published a best-selling book titled "The Bible Code," in which he claimed that the Bible contained a code (hidden in numbers and letters) accurately predicting past world events. Drosnin's work was later refuted, with critics demonstrating that the "meanings" he found were simply the result of selectively choosing data sets from a vast sea of random letters.
Similar "hidden codes" were found in other books such as "Moby Dick" and "War and Peace," demonstrating that any sizeable text can produce such codes if you look long enough.
In psychology, the tendency for the human mind to find coincidences, patterns, and connections in random data is called apophenia.
Ƹ̵̡Ǫ̵́ÌÆ· Apophenia
http://en.wikipedia.org/wiki/Apophenia
Apophenia is the experience of seeing patterns or connections in random or meaningless data. The term was coined in 1958 by Klaus Conrad,[1] who defined it as the "unmotivated seeing of connections" accompanied by a "specific experience of an abnormal meaningfulness".
