It would be interesting to be able to calculate exactly how fast we are moving in relation to an absolutely inert point.

ie--the rotation of the planet, combined with our orbit around the Sun, combined with the Solar System's orbit in the Milky Way, combined with the Milky Way's movement in the Universe.....

It's obvious too, that it will all add up to...2012 - right?

Seriously tho', it is only spin, or rotation, that keeps us all from being at the bottom of a gravity well somewhere, be it solar, galactic, or whatever.

According to this approximately 1,342,000 mi/hr - relative to the Universe, which could be moving as well, but so far no one has found a way to measure that.
