Earth Changes have been avidly studied throughout many cultures; the ancient Mayans being the most captivated by evolutional earth changes. Earth changes were tracked by Mayans through cycles and cycles of time. These wisdomful Mayans were predictive of a possible, cataclysmic earth changes occurring on December 21, 2012. Bizarrely, this date conjuncts with an astronomical event of grand prepulsion. This earth changes will haphazardly, but clearly coincide with a rare astonomical episode. On this particular day, the Sun will conjunct the intersection of the Milky Way and the plance of the ecliptic. By Mayan calculations, this cosmic cross correlates with the "Sacred Tree by the Maya."
A phenomenon named "the precession of the equinoxes," causes the Earth's wobble to last nearly 26,000 years. Since that time, the Winter Solstice sunrise has meticulously shifted toward the Galactic Center at a snail's pace. By counting revolutions, Mayans were able to calculate future dates in history for major Earth changes and transitions.
Does this mean that our Earth's life will ultimately face its demise? Perhaps, but it may also mean that a "new world age" will evolve. A grand transformation of massive forces will occur. In this time, the Age of Pisces will transcend to the Age of Aquarius -- the Sun sign of brotherly love. Perhaps, the earth changes that are coming, usher in a revolutional time of renewed hope and peace.
