Experimental Evidence for Unexpected Coupling Between Radial Stress and Gravitational Potential

Despite the successes of Einstein’s General Relativity (GR), a comprehensive understanding of how radial stress contributes to gravitational fields remains elusive. This study directly investigates this open question through a novel experimental apparatus designed to isolate and measure subtle gravitational effects induced by radial stress within rapidly rotating masses. Our findings reveal an unexpected anisotropic gravitational influence along the plane of rotation, deviating from the expected scaling predicted by the gravitational constant and challenging the conventional understanding of rotating mass in GR. This observed anisotropy cannot be readily explained by standard gravitational models or readily dismissed by other known forces and experimental error. The results suggest a potential need to refine our understanding of gravity in systems with high rotational energy densities, particularly for astrophysical phenomena such as neutron stars and galaxy evolution, where unexplained deviations from GR persist.
