Our solar system is part of a huge disc shaped collection of stars and planets called the Milky Way. We’re located somewhere on the edge of the disc, slightly above it. But very soon we’ll be moving to the bottom of the disc. This change, from top to bottom, begins on December 21, 2012.
What makes 2012 significant is that it coincides with the alignment of the center of the Milky Way galaxy, our sun, earth, and the large planets.
