| Jun 10, 2015 at 20:28 | comment | added | Michael Seifert | "Invariant" means that it is observed to be the same by different observers passing through one particular spacetime point; this doesn't imply that the quantity $u_\mu u^\mu$ is the same at different points along the geodesic. As an (imperfect) analogy, two people using Euclidean coordinates rotated relative to each other will agree that the electric field at a particular point has a particular magnitude; but that doesn't imply that the electric field has a constant magnitude everywhere in space. | |
