Abstract

The nodes of the `geometric trinity' are: (i) general relativity (in which gravitational effects are a manifestation of spacetime curvature), (ii) the `teleparallel equivalent' of general relativity (which trades spacetime curvature for torsion), and (iii) the `symmetric teleparallel equivalent' of general relativity (which trades spacetime curvature for non-metricity). One popular reformulation of (iii) is `coincident general relativity', but this theory has yet to receive any philosophical attention. This article aims both to introduce philosophers to coincident general relativity, and to undertake a detailed assessment of its features.
