Doctor Who (Doctor Who) (2005) (№ 393197)

When the child is first said that the Earth rotates, it doesn't feel real, because everything around stands still and never moves. I can feel it. The Rotation Of The Earth. The earth beneath our feet is spinning at a speed of 1,600 kilometers per hour and the entire planet goes around the Sun at a speed of one hundred thousand kilometers per hour, and I feel like we're flying in space: you and me. We try to cling to this planet, because if we fall... That's who I am.
