The doomsday theory arose from a non-Maya Western idea, not a Mayan one. Mayas insisted that the world would not end in 2012. The Mayas had a talent for astronomy, and enthusiasts found a series of astronomical alignments they said coincided in 2012. Once every six hundred forty thousand 640,000 years, the sun lines up with the center of the Milky Way galaxy on the winter solstice, the sun's lowest point in the horizon. The last time that happened was on December 21, 2012, the same day the Maya calendar expired. The modern doomsday myth was bolstered by several ostensibly scientific reasons for a disaster, including a pole shift, the "return" of Planet X or the Sun's sinister counterpart Nemesis, a galactic, planetary, or other celestial alignment, global warming, global cooling, a massive solar flare, or a new ice age. None had any basis in real science. For example, the "galactic alignment" between the sun, Earth, and galactic center happens every December. The best alignment was reached in the 1990s, and was accompanied by its own set of doomsday theories. Alignments since then have been increasingly poor.
