Earth aligns with the our Milky Way galaxy center.
Several years ago I tripped some documentation indicating that the Mayan calendar ends on December 21, 2012. Some time later I stumbled upon some information suggesting that December 21, 2012 would mark the date at which the solar system aligned with the center of the galaxy. Still other sources talk about a shift in the poles of the planet earth.
Over time, I've tripped over more and more information and everyone writing about 2012 is pretty convinced that we're in for the end of the world or the universe as we know it or the end of time.
Here are some references. You're on your own ... but there sure are some interesting theories.

Pole Shift before 2012?
I wonder if there shouldn't be a ceremony like mariners hold for people who cross our planet's equator ... the Court of Neptune Rex? But who would oversee the heavens? I suggest Orion.
