Differential Hydrostatic Detector for Measuring the Temporal Difference Between Gravitational and Light Signals During a Solar Eclipse

The propagation speed of the static gravitational potential has never been measured by a direct operational method. Existing evidence consists either of indirect observations — orbital stability, light deflection — or results of complex mathematical processing within the same model being tested. LIGO results concern exclusively the dynamic regime of gravitational waves under catastrophic mass accelerations and were obtained via an electromagnetic reference standard without independent verification by a fundamentally different method — and therefore cannot be considered an answer to the question of the static potential. We propose the first direct operational test by measuring the temporal difference X = Tbreak Tgeom between an anomalous jump on a mechanical load cell and the astronomically calculated moment of geometric contact C1. The experiment employs two independent physical channels — hydrostatic and barometric — which detect the same effect through different media: water and atmosphere. Coincidence of breaks in both channels constitutes mutual confirmation from two physically independent measurements. All scenarios are considered equally possible. The author has no prior hypothesis regarding the expected outcome.
