Gravitational lensing is traditionally interpreted as a geometric consequence of spacetimecurvature. This description is predictive but not generative: it does not identify the physicalmechanism that produces curvature. The Cohesion UFT 1, 2, 3 derives curvature fromlocal field density as K = ∇2Dst and predicts light bending through the density gradientequation d2x/ds2 = −∇Dst. In this framework, gravitational lensing is the optical responseto a density gradient — the same mechanism that produces acoustic lensing, thermal lensing, and plasma lensing. The theoretical prediction is established in prior Cohesion UFT papers and is not rederived here. The central contribution of this paper is a laboratory protocol demonstratingthe Cohesion UFT’s density-gradient lensing mechanism at bench scale. A coherent laserbeam directed through an acoustic or vibrational standing-wave field — a controlled, measurable density gradient — should exhibit deflection, phase delay, and oscillatory modulation analogous to gravitational lensing. This experiment is achievable with standard opticslaboratory equipment at a cost under 5, 000 and would provide the first direct tabletopdemonstration of the Cohesion UFT’s curvature-as-density mechanism. Three specific predictions are stated that distinguish the Cohesion UFT interpretationfrom the geometric GR account, and one of which — the oscillatory modulation frequencymatching the acoustic driving frequency — is not predicted by GR and constitutes a cleandiscriminating test.
