I think this may sound odd and strange, the idea ocurred to me while i was watching a TV program about GR.

If Einstein and other proved that the equations of motion could be derived from Geodesic, or that point particles moved on Geodesic under no forces, could it be applied to QM

I mean , for example the function $$P(r,t)=|\Psi (r,t)|^{2}$$ is some kind of minimal surfaces, in the sense that it would minimize the integral taken over R-4

$$A(\Omega)= \int_{\Omega} |Gra(P(r,t))|^{2}dxdydzdt$$
