Question of Planckian "Action" in Gravitational Wave Detection Experiments

It is shown that in the absence of a purely gravitational measurement of Planck's constant one cannot at present rule out the possibility that the ripples in the curvature of the fabric of spacetime may be scaled by a more diminutive "action" whose detection requires sensitivities beyond the standard quantum limit. An experiment that could unequivocally test this possibility is suggested.
