The most common question people ask about 2012 usually deals with what, if any, science there is behind it. This ties into the thrill of traveling in the Mundo Maya in 2012 -- to visit the various stelae and inscriptions with relevance to the Maya cosmovision and calendar. Luckily, there are plenty of these -- both in situ at the archeological sites, and in museums around the world.
In the video above, Dr. Mark Van Stone, professor and author of 2012: Science and Prophecy of the Ancient Maya, explains various important Maya glyphs at the Museum of Man in San Diego. This first explanation of Stela C from Quirigua, covers the 3114 BC start-date of the Long Count which will end on December 21, 2012.
As he explains: "The text tells us the names and actions of five actors in part of the Maya Creation myth of 13.0.0.0.0, which is 3114 BC in our calendar. This 13.0.0.0.0 date will repeat in December 2012, which is why so many people call it the 'end of the calendar' and predict a tremendous Change in our world."
For more of the science behind the Maya prophecy and 2012, read Dr. Van Stone's book, 2012: Science and Prophecy of the Ancient Maya [1], a full-color, 172-page book "inspired by Maya inscriptions, astronomical knowledge, math, and myth."
