The document discusses the Mayan prophecy that the year 2012 would mark a major transition or end of the current world age, as predicted by their extensive astronomical and calendar studies. The Maya developed a precise long count calendar cycle of about 26,000 years, with the fifth and final cycle ending in 2012. Their calendar was based on observations of lunar, solar, and galactic cycles. The Maya believed these cosmic cycles paralleled human consciousness and spiritual evolution. The document outlines NASA findings that solar magnetic field reversals in 2012 could significantly weaken Earth's magnetosphere and cause widespread electrical grid failures and climatic changes, posing major threats to human civilization.
