Sandra Noble, executive director of the Foundation for the Advancement of Mesoamerican Studies, Inc. in Crystal River, Florida. To render December 21, 2012, as a doomsday or moment of cosmic shifting, she says, is "a complete fabrication and a chance for a lot of people to cash in.
Like she has anyway of knowing whether or not it's a moment of "cosmic shifting" or what that would signify. Speaking of somebody cashing in on MesoAmerica herself, of course.
Let me suggest that you take a peek at the work of Terrence McKenna. Not the psychedelic plants stuff, the "Time Zero" program and resultant time mapping.
Briefly, it's a theory of time drawn out of mathematical permutations of the I Ching--itself a document based on time, on change (which is what time is made of, actually). Jung's idea that it dealt with "syncronicity" is a very simple and basic concept of what this whole study is all about, and suggests a document based on time.
What the Time Zero business graphs, essentially, is "novelty". Again, change, new ocurrence. It plots a period of decreasing novelty--an entropy of time. And charts the increase of novelty over the peaks and valleys of a "time wave". The current wave approaches infinity on Dec. 12, 2001.
Now there are many ways of discounting this, especially without familiarizing one's self with the material. (I'm continually astounded at how many people in forums devoted to speculative fiction cite science--what they got taught--to attempt to rule out speculation.)
But this thread asked for thoughts on the subject, and there is thinking on it that goes way beyond and Nostradamus or bearded nut on the street with an end is nigh sign.
Those interested can start with an overview of Time Zero
here.
Time Zero was developed almost two decades ago, indepently of the Maya Calendar thing. There is a blog that shows some of the ties between them
