The Mayan Calendar
2012 gained the patina of doom with the best-selling 1966 book “The Maya” by Harvard archaeologist Michael D. Coe. He noted that the Mayan culture’s famously complex “Long Count” calendar simply ends on 12/21/12, speculating that civilization might come crashing down on that date. Other scholars argue, however, that the Mayan calendar would merely flip over like an odometer that reached 100,000 miles.

Galactic Alignment
Astrologers have also pointed out that during the winter solstice of 2012, the orbital planes of the solar system and the twelve Zodiacal constellations will intersect with the “Dark Rift” — a black bit of the Milky Way located next to Sagittarius. Some argue this intersection is precisely why the Mayans — who were brilliant astronomers — ended their calendar when they did. But other astrologers believe that this conjunction will usher in a great shift in consciousness.

Timewave Zero
And then there’s counterculture thinker Terence McKenna whose Timewave Zero theory — drawing off of elements from the “Itching,” the teachings of philosopher Alfred North Whitehead, and modern fractal mathematics — which determined that 12/21/12 is, you guessed it, the exact date of a profound change in world. Roughly speaking, the Mayans, astrologers and McKenna are all predicting global doom or the dawning of the Age of Aquarius.

The SUN
So if the apocalypse is set just in time for holiday shopping season three years from now, how exactly will the world end? One theory that actually has some traction in the scientific community is that a solar flare will cause a sudden shift in the magnetic orientation of the Earth’s poles, causing all kinds of planetary problems like volcanic eruptions and earthquakes. NASA is predicting strong solar activity around 2012 and there’s evidence that the magnetic poles are slowly weakening, something that reportedly presages a reversal. Of course, most scientists think that this reversal will take centuries, not days, to occur.

Most of this info is from the review on the 2012 preview, but it fits. WHAT SHOULD I DO OH GREAT AND POWERFUL ANSWER PEOPLE OF YAHOO!!!
