Text: "In General Relativity it is well-known that any change of spatial energy density is a priori a curvature of spacetime, and that an EM wave is an oscillating change of spatial energy density, hence an oscillating curvature of spacetime. So the EM wave does propagate in curved spacetime; in fact it identically is "curvature of spacetime" dynamics that is propagating."
