Abstract
According to recent arguments, the geodesic principle strictly interpreted is compatible with Einstein’s field equations only in pathologically unstable circumstances and, hence, cannot play a fundamental role in the theory. It is shown here that geodesic dynamics can still be coherently reinterpreted within contemporary relativity theory as a universality thesis. By developing an analysis of universality in physics, I argue that the widespread geodesic clustering of diverse free-fall massive bodies observed in nature qualifies as a universality phenomenon. I then show how this near-geodetic clustering can be explained despite the pathologies associated with strict geodesic motion in Einstein’s theory.
