Theories don’t explain- they predict. Consider gravity- Newton’s law tells you the attraction between two masses, and it’s mostly consistent with the mostly elliptical orbits that we observe the planets moving in.
The gravitational equation is effectively just* a summary of the observed data, so it is no surprise that it predicts. I believe Monkeymind finds this unsatsifactory, but I’m still not sure exactly how. Perhaps he defines theory differently. I’m a little curious what actually causes the Earth to pull on me, rather than, say, push me away. At the time Newton said he had no hypothesis for that, but now the same equation constitutes a theory or explanation? I feel like these terms are used a little too loosely.
*Not to imply that finding the equation that fit the data wasn’t an important achievement
