Just wondering... so the conception is that gravity is not really a "force" but rather the consequence of shortest-path motion through curved geometry. Are there analogues for the other forces? I know gravity is not yet theoretically unified with the other forces. But is there nonetheless some conception of, say, the attractions and repulsions of the electromagnetic force actually being a consequence of motion of matter through strange geometry rather than a "force" as we usually think of the word? If not, what is the theoretical mechanism of the attractive/repulsive properties of non-gravitational forces and how do they differ from gravity?
