The ground under you is moving, really fast. Along the equator, the Earth rotates at over 1,000 miles per hour, twenty-four hours a day, while orbiting the Sun at a little over 67,000 miles per hour. That’s 1,600,000 miles per day. Meanwhile our solar system is in motion relative to the Milky Way galaxy at more than 1,300,000 miles per hour, covering just shy of 32,000,000 miles per day. And so on.
