"I can feel it. The turn of the Earth. 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, and I can feel it. We're falling through space, you and me. Clinging to the skin of this tiny little world, and if we let go… That's who I am. Now forget me, Rose Tyler. Go home."
The Doctor, "Doctor Who"
