Two objects A and B in other space of masses $M1$ and $M2$ are separated by a distance $r$. The $Δg$ with $Δh$ is not negligible. Integrate a function $f(t)$ with time as an input for velocities $v1$ and $v2$ of objects A and B respectively taking into account $g$ at a point changes due to either of the objects because both objects accelerate towards each other?

    $\begingroup$ As far as I know, there is no analytic solution for this in GR. $\endgroup$ – G. Smith Nov 22 at 6:05

    $\begingroup$ @Ace also mention your work. Where are you facing problem. Then we will have a decent discussion $\endgroup$ – Anonymous Nov 22 at 7:49
