Are you sitting still?
You may think you are, but you’re not. You never can be.
As the earth turns, a person standing on the surface at the equator is zipping along at 1,100 miles per hour toward the east. (Do the math: a point at the equator has 24 hours to get all the way around to the same place, so 25,000 miles, which is the circumference of the earth, divided by 24 hours = 1,100 mph) Depending where you are on earth you could be moving at up to this speed. This is the biggest reason why we launch rockets toward the east; they’re getting a nice free boost in that direction just sitting there on the launch pad. (Naomi and I are headed for FL today, by the way, to witness a 3 December launch.)
And the earth takes 365 days to complete one orbit around the sun, which is 94 million miles away from us. (Do the math: our orbit circumference is 2 x pi x 94 million = 590,619,418.9 miles, divided by 365 days = 1,618,135 miles that the earth speeds along its orbit per day, or 67,422.3 mph on average.
And the entire solar system, the sun and all its family of planets and moons, is racing around the center of our Milky Way Galaxy at 514,000 mph. (A speed at which you would circle the earth at the equator in just 2 minutes, 54 seconds.)
And the entire Milky Way Galaxy, with its approximately 400 billion suns (including ours) all arrayed in a beautiful glittering spiral pattern, is flashing through space at an incredible 1.3 million mph.
So the next time you tell your child to sit still, dammit, be advised that she or he simply cannot. Not by a long shot.
And neither can you.
