Exactly what will happen on December 21, 2012 still remains a mystery, but it seems that we are receiving stronger and stronger clues. The Mayans certainly placed great significance to this date. 

The Mayas were a mysterious and much advanced people who were superb mathematicians and astronomers. They were also blood-thirsty cannibals involved with human sacrifices. They devised (alien taught) one of the most accurate calendars known to man, far more accurate than the modern Gregorian calendar. Their calendar was created through extremely accurate observations of the sun, the planets, the stars and our own Milky Way Galaxy. They knew, through unknown methods, the exact location of the center of the Milky Way and attached great significance to the birth and death of stars at this center. They also possessed extensive knowledge concerning the 'Precession of the Equinoxes' and their periodicity which was necessary to create an accurate calendar and other time keeping devices. The Mayas viewed time differently than western man. The magnificent pyramids (constructed when?) were perfectly aligned to the Sun and were constructed in such a way that during the equinoxes, the setting Sun casts a shadow of a serpent (Kukulcan/Quetzalcoatl) descending on the northern steps of the pyramid. This effect could only be obtained by precise architectural and astronomical measurements and is most evident at the pyramid in Chichenitza.

The Mayan's astronomical knowledge was inherited from even an older and more mysterious civilization at Teotihuacan which contains the famous Pyramid of the Sun and of the Moon. The Pyramid of the Sun is perfectly aligned with the star cluster called the Pleiades which the Egyptians also took into account in building their pyramids at Giza. There is a connection between the ancient religious beliefs of the Sumerians, the Egyptians and the Mayas, especially as they relate to the creation of the universe, of the human race and of the future.

The Mayans had a glyph that represented a ‘black hole’ in the center of our galaxy. They tied their philosophy entirely on what they observed in the heavens. They believed that the center of our galaxy was a ‘Cosmic Mother Womb’ and that it gave birth to our world that went through cycles of birth, death and rebirth. 

December 21, 2012 will end the cycle and our world will end by fire,  but will be reborn in a new, different and more evolved form, possibly in the form of a ‘New Jerusalem’ that is described in Revelation. This will be the beginning of a new Sun or the ‘Sixth Sun’ according to the Mexicans (Aztecs).

On December 21, 2012 ,which coincides with the Winter Solstice and as the Sun sets west of Chichen-Itza, a pattern of shadow and light will project the Plumed Serpent (Quetzalcoatl) descending on the stairs of the pyramid that has a large head of a serpent sculpted in rock at the base. This occurs twice in Chichen Itza every year, but on the Winter Solstice of December 21, 2012 something very special will happen. 

As the Sun sets in the early afternoon, the shadow of the pyramid's northwest edge will project a moving pattern of light that joins and illuminates the sculpted serpent head at the base of the stairway. Within a thirty-four minute period, the serpent, formed by this play of light and shadow will appear to descend to the Earth, as the Sun leaves each stair, going from the top to the bottom. This combined effect creates the visual appearance of the body of the serpent descending the pyramid. In addition, on December 21, 2012, the tail of the serpent projected up from the top of the pyramid will be pointing precisely to the star cluster Pleiades. 

The pyramids at Teotihuacán which means 'City of the Gods', constructed by a Meso-American civilization just north of Mexico City that preceded the Mayans, are also aligned to the Pleiades as are the Egyptian pyramids at Giza. In addition, on December 21, 2012 at around 11:11 universal time, there will be a precise alignment of our Sun with the Galactic center (Hunab Ku).
