Why does the Mayan Calendar stop at December 2012?
The Mayans could see the stars and the planets and by sight distinguish between the two by the apparent movement among the fixed stars. The validity of the claim is not tested by any one. The Mayans were descendants of the Olmec empire, with records and codices being destroyed by fire by the Spanish conquistadors. But there was always a oral tradition. We don’t know what will happen on 12/21/2012, but the time and date are related to a phenomenon called the precession of the Equinoxes. It’s the end of a five thousand year cycle. The Mayan calendar is remarkedly accurate due to their computation of the value of pi, which value was more reliable than any European pi.
