2012 Galactic Alignment - 21-12-2012 Solstice Sun Conjunction With Great Rift
The Milky Way2012 Maya Calendar Dark Rift Conjunction
On December 21st 2012 the Long Count Calendar used by the ancient Meso-American peoples such as the Maya, Aztec, Toltec and Olmec will end one great cycle of 13 Baktun (5125.26 years). The creators of this system were able to calculate and track interesting cycles of nature such as eclipse and conjunctions.
The length of sub-cycles matched natural cycles such as human gestation local snakes shedding their teeth as well as the number of human digits and major joints. They understood the orbits of the observable planets and knew the lengths of each ones journey around the sun. The minds behind this system gave birth to some 24 separate calendar systems capable of tracking both astronomical and non-astronomical cycles within nature.
The winter solstice of 2012 will occur at 11:11 GMT on of course 21-12-2012 the same day the Long Count flips over. On that morning the sun will appear to rise into the patch of sky we refer to as the galactic centre or nuclear bulge. It is the location of the super-massive black hole at the centre of rotation for the Milky Way galaxy.
In itself the appearance of the sun rising here is not a particularly unique event. The phenomena can be observed for winter solstice dates of numerous years either side of 2012. The only unique aspect of this year will be the sun appearing to just touch one part of the Dark Rift (Great Rift) that snakes its way along the Galactic Equator. This is an area of the night sky considered important to Maya cosmology most notably with respect to spiritual rebirth mythologies.
Although commonly known as the ‘Galactic Alignment’ the correct term for the event should really be the ‘Galactic Conjunction’. Astronomical alignments refer to three celestial objects in shared orientation. Astronomical Conjunction is an alignment of two cosmic objects or bodies as seen from the Earths perspective.
For a simple example we can imagine three planets in alignment. The factuality of this event would not be effected by your location in the solar system. Whether you are stood on the Moon or on the Earth the three planets would still be aligned. When an alignment, such as that of the Sun and the Dark Rift, is only happening from the perspective of the Earth then it is a Conjunction. This is clearly the case for 2012 calendar end-date.
