I don't call it the theory of gravity, I call it the Law of Gravity. Or the Newtonian Laws of Physics. A theory, in the general sense of the word, is an analytic structure designed to explain a set of observations. A Law is a generalization that describes recurring facts or events in nature Laws are predicated on reproducible experiments. An idea is a theory before the experimental evidence is amassed and confirmed.
