When scholars first began to study the ancient Mayan culture, which flourished in Latin America during the first millennium, they were surprised to discover how highly developed Mayan knowledge of astronomy was. The Mayans were able to predict astronomical events such as eclipses with perfect accuracy far into the future. But something else struck the scholars too : for some reason the Mayan calendar came to an abrupt end on December 21 2012. What did this mean?
It means that the Mayans didn't survive long enough to institute the next edition of their calendar. Or it means that you also believe the world began August 13, 3114 BC, if the beginning of the Great Cycle on the Long Count Calendar is accurate. Since I haven't seen any calendars printed for 2012 yet, I guess western civilization is predicting the end of the world on Dec. 31 2011.

All the planets align. That is the significance of that date. The effects of that are undetermined.
No, they won't. Quit reading astrology books and start reading astronomy books. Planetary alignment is a virtual impossibility in our solar system. Even planetary configurations (not alignment, only when the planets are in the same quadrant) of the five 'classical' planets with the sun and moon only happen about every 40 years. The last time was in May 2000 and next is in 2040.
The worst part about doomsday predictions is that someday some morons prediction will be right through nothing more than sheer, dumb luck.
