and yet it moves

It's like when you're a kid. The first time they tell you that the world's turning and you just can't quite believe it because everything looks like it's standing still.
The ground beneath our feet is spinning at a thousand miles an hour. And the entire planet is hurtling around the sun at sixty-seven thousand miles an hour. We're falling through space, you and me. Clinging to the skin of this tiny little world. (The Doctor (9) )
