2012 Doomsday Bullshit

In the solar system, gravity causes the sun and planets to share the same plane of orbit. In the night sky, this plane is known as the ecliptic. The twelve Zodiac constellations move along or near the ecliptic, and over time, appear to recede counterclockwise one degree every 72 years - that is, from our perspective looking up from the ground. This movement is attributed to a slight wobble in the earth's axis as it spins. As a result, approximately every 2160 years, the constellation visible on the early morning of the spring equinox changes. This signals the end of one astrological age (currently the Age of Pisces) and the beginning of another (Age of Aquarius). Over the course of 26,000 years, the precession of the equinoxes makes one full circuit around the ecliptic.
This phenomenon underlies the principle of "galactic alignment", a rarely occurring intersection of the earth, sun and galactic equator. The next alignment is claimed (wrongly, according to Maya scholars) to coincide with the end of the Mayan Long Count calendar, which is claimed (wrongly again) to coincide with the winter solstice of December 2012. Former software engineer John Major Jenkins is credited with the premise that the classical Mayans anticipated this conjunction and celebrated it as the harbinger of a profound spiritual transition for mankind.
