The law of inertia and momentum made outside divine intervention unnecessary for planetary motion.
Evidence
The solar system, at any rate, was kept going by its own momentum and its own laws; no outside interference was needed. There might still seem to be need of God to set the mechanism working; the planets, according to Newton, were originally hurled by the hand of God. But when He had done this, and decreed the law of gravitation, everything went on by itself without further need of divine intervention. — Bertrand Russell, History of Western Philosophy, 1978
