The Galactic Center is the rotational center of the Milky Way galaxy. It is located close to the stinger of Scorpio and the arrow of Sagittarius. In December 2008 it was confirmed by German scientists that the Galactic Center consists of a supermassive black hole.
The Mayan people identified the Galactic Center as the Hunab Ku, which to the Maya represented the supreme God and ultimate Creator. It represented the gateway to other Galaxies beyond our Sun as well as all of the consciousness that has ever existed in this Galaxy. Hunab Ku, according to the Maya, is also the consciousness which organized all matter from a "whirling disk" into stars, planets and solar systems. Hunab Ku is the "Mother Womb" which is constantly giving birth to new stars, and it gave birth to our own Sun and Planet Earth. They also believed that the "Creator" directs everything that happens in our Galaxy from it's center through the emanation of periodic "Consciousness Energy" bursts. Today, modern astronomers have verified that at the center of our Galaxy is a "whirling disk" with a "Black Hole" at its center that is both swallowing and giving birth to stars.
The Hunab-Ku was originally square shaped. It contains octagonal symmetry which is sometimes linked to the center of the Milky Way.
The Mayan Calendar predicts that a superwave of energy is going to come from the Galactic Center when the Mayan Calendar ends on December 21 2012 11:11am UT. Such Galactic energy bursts are predicted by Paul LaViolette in his book Earth Under Fire. LaViolette explains that all spiral galaxies, such as the Milky Way, go through a "Seyford" phase where their energy output increases dramatically from explosions in the center of each galaxy. Possible evidence of these waves of energy are layers of Rhodium and Iridium found in ice core samples which mark periods of around 13,000 to 26,000 years. It takes the earth about 26,000 years to complete a precession of the equinox. One "month" of this galactic year is about 2,160 years long. This time period, along with clues to a double-catastrophe and safe zones on earth, are found encoded in the Cyclical Cross at Henday. The last chapter in Fulcanelli's Mystery of the Cathedrals is dedicated to deciphering the clues on the cross.
