So in General Relativity you can solve the geodesic equation for my body and find that it's "trying" to travel a path through the center of the earth due to local curvature. I remain on the ground as it is continually intercepting me from this path.
This explanation doesn't leave any room for my personal mass to play a role, and so it appears to fail in explaining the obvious fact that it's much more difficult to lift a car away from the ground than myself.
So what's going on here? Obviously I generate a gravitational influence which will change the geodesics slightly, but I estimate that the difference in this effect (between me and the car) cannot account for the difference in weight. Maybe I'm wrong? If so, how exactly does my gravitational curvature result in the difficulty one has in lifting me?
