Indeed, we have no idea what is the connection between time, space, mass and other forces. We have some findings (hey! mass is intimately connected to curvature of spacetime!) and approximations in forms formulae we know, but that's just it. I think our physics is akin to epicycles before we found actual place of Earth in solar system and shape of planet orbits.
