I was up on the roof yesterday, watching the sun go down and sitting really still, thinking. At this latitude, the Earth’s surface is rotating eastward on its axis at 750 miles per hour, while sailing west around the sun at 20 miles per second. The sun, meanwhile, is in the outer spirals of our galaxy, orbiting up and to my left around the center of the galaxy at 150 miles per second, as our galaxy barrels in God knows what direction at 200 miles per second. All this is happening as the universe itself expands perhaps even faster than the speed of light (186,000 miles per second).
So much for thinking I was up there sitting still.
