motion?
eg. Why is the earth spinning at 1,000 mph on its axis, while orbiting the sun at 66,000 mph, while our solar system is orbiting around our little neighborhood in the galaxy at 43,000 mph, and that little local neighborhood is spinning with the galaxy at 483,000 mph, and our galaxy is moving at 1.3 million mph?
If there is no such thing as a perpetual motion machine why is there motion? Was there a beginning to the motion... and matter?
