Is there historical and scientific evidence supporting a theory that the Maya had knowledge of a significant 2012 event?

Some people question whether the Maya actually knew something was going to happen on Winter Solstice, December 21, 2012. They point to a lack of specific mention in their writings and scientific confirmation. These naysayers are wrong on both counts.
The next series of blogs will discuss the historical and scientific basis of what I will call for convenience sake, the “Maya 2012 End Time Prophecy.” The conclusions reached after research and analysis surprised even me. I’ll start with this question: Did the Maya leave a written record revealing that a cosmic event will occur on December 21, 2012?
We need to first discuss why the Maya calendar date that equates to our date of December 21, 2012 has become a matter of concern as the date approached.
Basically, the Maya believed that the world around them suffered catastrophic events four times in the past and that the fifth such event would occur on the Winter Solstice, 2012 date. Rather incredibly, the events that they believed caused global annihilation in the past roughly mirror Biblical disasters such as the Flood and the cataclysmic destruction of ancient cities by fire from the sky and eruptions of the earth.
We also know from geological evidence that life on our planet was almost completely wiped out a number of times before recorded history. These events, such as mega volcanoes and asteroid and comet strikes, including ones the Maya would have knowledge of, will be discussed later.
It needs to be emphasized again that the Maya were a highly advanced and literate culture. This has to be important to keep in mind because there is misconception that began immediately after the conquest by Europeans that the Aztecs, Maya and other peoples of Mesoamerica were savages. That concept arose to justify the destruction, looting and rape of their entire civilization—behind it was Spanish lust for treasure and religious zealots.
The fact they practiced human sacrifice was perhaps the most serious charge, ignoring the fact that many pagan European cultures did the same and the Romans in fact kicked their form of human sacrifice up to a high level by pitting untrained, ill-equipped people against savage beasts and professional warriors.
One way to judge the state of a culture is by looking at how complex their language was. Like the Egyptians, the Maya had a well developed written language based on hieroglyphics, a system of mathematics and were perhaps the finest astronomers of the ancient world, surpassing cultures such as the ancient Greeks, Persians, and Chinese who made studies of the sky.
The Maya produced tens of thousands of books, a recorded history of their entire civilization. What happened to these books and from clues left behind what I believe the books contained, will be discussed in the next blog.

The above is my co-author’s response to my original blog, which now follows:

Did the Maya have a serious scientific reason for their belief in a 2012 apocalypse?

The date they picked for their apocalypse is December 21, 2012. At that time our planet, moon and solar system will align with the heart of the galactic plane, in which scientists now know a supermassive black hole resides. The Maya viewed that black abyss—which they called “the Dark Rift”—as a kind of hell world, out of which the Black Tezcatlipoca would unleash the dark demons of everlasting night, which would then descend on the earth and annihilate humankind. This alignment only occurs once every 26,000 years, which closely approximates the combined duration of the five Mayan “Sun Ages.” I say “approximates” because the precise length of each of those “Sun Ages” is not known. They come to around 5200 years each, which would equal 26,000 years. In other words, the first “Sun Age” would have roughly coincided with the earth’s last alignment with the galaxy’s core. On 12/21/2012 at 11:11 PM Universal Time earth will experience its first galactic alignment in that 26,000 period. The Maya believed that date marks the end of the Fifth Sun Age.

They Maya also seemed to know—for reasons that are still unclear—that the Milky Way galaxy was a spiraling disk and that we orbited along its edge. We know this because the Mayan glyph for our Milky Way—which they sometimes called “The Tree of Life”—is a spinning disk.

I’m not suggesting the Maya viewed the universe exactly as we do or that they had our mathematical and the scientific sophistication—only that their vision of the 2012 apocalypse was based on closely studied astronomical observations and mathematical calculations as well as mystical divination.

I’ve done a lot of national radio and some TV for this book, and many people ask if extraterrestrial beings gave the Maya these unique insights. My answer is somewhat oblique. In the end the Maya could not have inferred these insights into our galaxy from their mathematics, science or from direct observation, and these insights imbued their hieroglyphic language, their religion and their life. They weren’t irrelevant, ephemeral observations. It seems to me they gained them either through a kind of preternatural revelation unimaginable to us or someone told them. I do not see a third alternative. I wish someone would come up with one.

I also do not see how we can dismiss out of hand their End-Time prophecy, if we cannot explain how they arrived their other uncanny perceptions about the nature of our galaxy.
