Experimental Refutation of Relativistic Delay in the Sun's Gravitational Potential via Differential Hydrostatic Detection.

This paper presents a precision experimental method for detecting the Sun's gravitational response using a differential hydrostatic system. The setup consists of a horizontal baseline of communicating vessels and a 5-meter vertical barometric baseline using BMP580 sensors to isolate the gravitational signal from atmospheric noise. The experiment aims to determine whether the gravitational force vector is directed toward the optical or the true geometric position of the Sun. A detection of the peak response at the geometric zenith would provide direct evidence of instantaneous gravitational action at a distance, challenging the relativistic "retarded potential" model.
