2012 Doomsday

The 2012 phenomenon comprises a range of eschatological beliefs according to which cataclysmic or transformative events will occur on 21 December 2012. This date is regarded as the end-date of a 5,125-year-long cycle in the Mesoamerican Long Count calendar. Various astronomical alignments and numerological formulae have been proposed as pertaining to this date, though none have been accepted by mainstream scholarship. A New Age interpretation of this transition is that this date marks the start of time in which Earth and its inhabitants may undergo a positive physical or spiritual transformation, and that 2012 may mark the beginning of a new era. Others suggest that the 2012 date marks the end of the world or a similar catastrophe. Scenarios suggested for the end of the world include the arrival of the next solar maximum , an interaction between Earth and the black hole at the center of the galaxy, or Earth's collision with a planet called "Nibiru".

Scholars from various disciplines have dismissed the idea of such cataclysmic events occurring in 2012. Professional Mayanist scholars state that predictions of impending doom are not found in any of the extant classic Maya accounts, and that the idea that the Long Count calendar "ends" in 2012 misrepresents Maya history and culture. Astronomers and other scientists have rejected the proposals as pseudoscience, stating that they conflict with simple astronomical observations and amount to "a distraction from more important science concerns, such as global waming and loss of biological diversity".

Apocalypse

There is a strong tradition of "world ages" in Mayan literature, but the record has been distorted, leaving several possibilities open to interpretation. According to the Popol Vuh, a compilation of the creation accounts of the K'iche' Maya of the Colonial-era highlands, we are living in the fourth world. The Popol Vuh describes the gods first creating three failed worlds, followed by a successful fourth world in which humanity was placed. In the Maya Long Count, the previous world ended after 13 b'ak'tuns, or roughly 5,125 years. The Long Count's "zero date" was set at a point in the past marking the end of the third world and the beginning of the current one, which corresponds to 11 August 3114 BC in the proleptic Gregorian calendar. This means that the fourth world will also have reached the end of its 13th b'ak'tun, or Mayan date 13.0.0.0.0, on 21 December 2012. In 1957, Mayanist and astronomer Maud Worcester Makemson wrote that "the completion of a Great Period of 13 b'ak'tuns would have been of the utmost significance to the Maya". In 1966, Michael D. Coe wrote in The Maya that "there is a suggestion ... that Armageddon would overtake the degenerate peoples of the world and all creation on the final day of the 13th [b'ak'tun]. Thus ... our present universe [would] be annihilated [in December 2012] when the Great Cycle of the Long Count reaches completion."
