Which is absolutely bang on, no?<br /><br />Almost; but what he has forgotten (probably being too contaminated with Aristotle) is that the heavenly bodies go in circles not straight lines *and this needs explaining*.<br /><br />This is absolutely key (cite: Feynman) because once you realise that what you need to explain in planetary motion is not the motion along the tangent, but the motion/acceleration *towards* the sun, you're naturally lead to the idea of the sun being the source of whatever force is doing this.William M.
