Perturbative Gravitational Force -- Lack Of Smooth Ricci Curvature -- Lack Of Gauge-Invariance

 A perturbative gravitational force is eminently associated, with the proximal local lack of a flat Ricci Curvature, to where such a just stated lack of a flat Ricci Curvature, may often tend to work to facilitate, the resultantly consequential proximal local lack of gauge-invariance.
