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?
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.

If you want an analyitic solution, don't hold your breath. It has been
my understanding that there is not even a two body solution to general
relativity.

I would be pleasantly surprised to know if I am wrong, though.


Thank you in advance.
