Note to Conspiracy Theorists: Time is an Abstract Concept Created By Man
The 2012 phenomenon comprises a range of eschatological beliefs that cataclysmic or transformative events will occur on December 21, 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 related to this date have been proposed.
A New Age interpretation of this transition postulates 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, or Earth's collision with a black hole or a passing asteroid or 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 proposed events as pseudoscience, stating that they are contradicted by simple astronomical observations.
