_So I know everyone is like, “What is the big frick’n deal about this 2012 Mayan thing?”
I'll tell it to you real simple.
_ Though every year, in December, the Sun and the Milky Way, from the surface of the Earth, appear to come into alignment, and every year, precession causes a slight shift in the Sun's position in the Milky Way. Given that the Milky Way takes between 700 and 1400 years for the Sun's December solstice position to precess through it. The galactic coordinate system (GCS) is a celestial coordinate system which is centered on the Sun and is aligned with the apparent center of the Milky Way galaxy.
Like many others I can’t help but wonder if anything will happen on, or around December 21, 2012. This date isn’t all just based on the Mayan calendar. There are many other ancient prophesies that count this date as important, like the “I Ching”, the Egyptian Phoenix Cycle, and not to mention the Hopi Indians. Each have interesting concepts of what will happen in 2012.
Do I think it’s the end of the world? Nah, that’s just media hype around a few individuals who haven’t researched the date. I seriously think it is just a reset. Like going from December 31, 2011, to January 1, 2012. The Mayan calendar just starts over.
Now the real tantalizing question is; how did the Mayan’s know we cross the center of the Milky Way galaxy on that exact date? Did someone tell them? If so, who?
Yet, I do think something major could happen. The Earths poles did flip at one time, and something was strong enough to force Venus to rotate the opposite direction than all the other planets in our system. Was it because we got too close to “Sagittarius A” that it messed with our polarity field? I hope not. Maybe being between Jupiter and the Sun, will keep us unflippable.
There is a belief that the Earth's magnetic field is weakening, which could precede a reversal of the north and south magnetic poles. Scientist say it takes a long time for a reversal to happen, but let’s face it, they really don’t know. They weren’t here when it happened.
Some debate whether there is a black hole or not. I believe there is, the universe is not random. We are circling around something big, and something powerful enough to keep our sun in its orbit.
Stars near the galactic center are believed to be orbiting a super massive black hole called Sagittarius A (Sgr A) (from Gillessen et al., The Astrophysical Journal, 692:1075–1109, 2009)
Based on observations by a group led by Reinhart Genzel have found the best evidence that there is a supermassive black hole lurking at the center of our galaxy. By watching 28 individual stars (above), it is possible to see that they share a common point around which they all orbit. But perhaps most interestingly, one such star (so called 'S2') was observed to complete a full orbit around the central point - the first time such an event has ever been recorded. From the speed and shape of the orbit of this star (and the others), it was determined that the central point must be relatively small, but with a mass equivalent to around 4 million times that of the Sun.
Again, how did the Mayans know we were aligning with the center of our galaxy on 12/21/12? It can’t be dumb luck.
