WebMar 5, 2024 · A partially successful change of coordinates for the Schwarzschild metric, found by Eddington in 1924, is (see problem 8): (6.4.1) t → t ′ = t − 2 m ln ( r − 2 m). This makes the covariant metric finite at r = 2 m, although the contravariant metric still blows up there. A more complicated change of coordinates that completely eliminates ...
