Under-Determinism and Philosophy

Newton's original theory of gravity is a force and this other weird variation where gravity comes from the curvature of spacetime, but it gives the same predictions as Newton's original theory. So you're saying there we have like two theories with different descriptions for what's unobserved. The underlying concept is simple and we'll be familiar to all sorts of folks. We find ourselves in situations just in our day-to-day lives where the body of evidence that we've gathered doesn't help us adjudicate between two theories.
