Perspective

The moon is traveling about 2300 MPH (more than 1/2 mile a second) in its orbit around the Earth. The Earth, spinning on its axis at about 1000 MPH, is traveling roughly 67,000 MPH (19 miles a second) around the sun, while the sun is zooming at 560,000 MPH (156 miles a second) around the hub of the Milky Way (the last time our sun was in it's present relative position on its galactic circuit, dinosaurs walked the earth!). And the Milky Way is going someanywhere even faster. Think about it: all that rushing around! And Sir Isaac, sitting under an apple tree was struck by an apple...so, where do you suppose IT was going? Well, it flew right into Sir Isaac's brain and became The Calculus, and our view of the cosmos has never been the same since... and then there was Einstein...

Gravity well done, if not overly distant. - dh
