  In the present work, it is shown that the geometerization philosophy has not
been exhausted. Some quantum roots are already built in non-symmetric
geometries. Path equations in such geometries give rise to spin-gravity
interaction. Some experimental evidences (the results of the COW-experiment)
indicate the existence of this interaction. It is shown that the new quantum
path equations could account for the results of the COW-experiment. Large scale
applications, of the new path equations, admitted by such geometries, give rise
to tests for the existence of this interaction on the astrophysical and
cosmological scales. As a byproduct, it is shown that the quantum roots
appeared explicitly, in the path equations, can be diffused in the whole
geometry using a parameterization scheme.
