Check Chapter 13. Simple arithmetic is all it took to shoot down the Michelson-Morley experiment. While I'm responding to this, I might add that repeating the old saw about Earth continuously falling towards Sun, should be balanced by stating that because of Newton's 2nd Law re: Momentum, Earth is also continuously flying off into space. Both statements are absurd, and mutually exclusive. Orbital balance is absolutely maintained by corrective negative feedback to any perturbations, such as the meteor impact at ~65 million years ago, that is thought to have wiped out the dinosaurs. Any perturbation to planetary orbit is almost instantly corrected by a change in orbital angular momentum, which restores centripetal/centrifugal balance. I don't need math to demonstrate a simple mechanical principle. Your weight-on-a-string serves quite nicely. As the weight is whirling around, just pull the string in a bit shorter, and angular velocity increases. What this demonstrates is that, if a planet is knocked a bit closer to the Sun by an impact, orbital velocity increases, thereby increasing centrifugal force, and re-stabilizing the orbit. Got to go, will get back on the other points ASAP.
