This paper introduces a new experimentally supported framework for understanding gravity, proposing that it originates from atomic nuclei rather than from mass or the curvature of space-time. Unlike Newtonian and Einsteinian models—which define gravity as a mass-based attraction or the result of space time deformation—this theory presents gravity as an electromagnetic force generated by positively charged nuclei. It introduces the concept of a "Nuclear Polarization Force" to explain gravitational interactions between nuclei and other bodies—neutral, negatively charged, or positively charged—through polarization and charge dynamics. To validate this theory, an experiment was conducted demonstrating measurable weight differences in objects when charged positively or negatively, compared to their neutral state. The results suggest that gravitational force is influenced not only by mass but also by electric charge. This model aims to unify gravitational behaviour across atomic, planetary, and cosmic scales, offering a new perspective on the dynamics of the solar system, black holes, and the expansion of the universe. By redefining gravity in electromagnetic terms, this research addresses existing gaps in cosmology and quantum gravity, potentially opening new pathways in fundamental physics.
