Similarly, let the second object have mass m2 and have motion described
by the equations x=g1(t), y=g2(t) and z=g3(t). Let their rotational
motion be described by f4(t), f5(t), and f6(t).

According to general relativity, what is the force between these two
objects?

The answer is:

1. For m1/m2~ 0 (m1 is a test particle). m1 moves along a geodesic
generated by m2. Only numerical solutions available. The force can be
approximated by solving numerically the field equations. Also known as
the'"restricted problem.

2. For m1/m2 finite. m1 now affects its geodesic path by contributing
to spacetime curvature. Solution does not exist. Force cannot be
calculated.


I am aware of the fact that problems like this often become quite
complicated in GR, but I am fine with an answer that contains such
elements as differential geometry and tensor analysis.

Just use Newtonian mechanics for a reasonable answer. GR will gets you
nowhere. Only losers care about GR. I have been asking the losers to
write down the GR equations for a simple spring-mass system. They never
did. GR is metaphysics blended with crackpot mathematics. If you want
answers Newton rules everywhere. Of course there is the crap of wek
field limit approximations, GPS, perihelion etc. but that si another
pile of crap evident now since:

1. GR predicts an order of magnitude less energy for cosmic radiation

2. Fails by a factor of a million billion times in gravitamagnetic
effects

3. Frame dragging never detected

4. Gravity waves never detected

5. Black holes only dreamed off.
