Can General Relativity be "translated" to a language of forces in the analogous way that Newtonian gravity can be formulated in geometric terms?
I know from "Gravitation" of Misner, Thorne and Wheeler(MTW) that Newtonian gravity can be formulated in a geometric language. Can we do the reverse for General Relativity? That is, could General ...
