Why is general relativity a geometric theory? The redshift argument revisited
Harvey R. Brown (Faculty of Philosophy, University of Oxford)
Abstract
A standard heuristic argument in general relativity textbooks for associating gravity not with a force but with curvature of space-time concerns the phenomenon of gravitational redshift of clocks. Yet there are distinct ways in which Pound-Rebka-type experiments are interpreted in the literature, and distinct ways in which the notion of curvature is related to redshift. A related argument common to a number of recent textbooks is found wanting.
