Experiment Findings Gravity is Electromagnetism: A Theoretical and Experimental Study
This research paper investigates the hypothesis that an object’s weight may vary depending on its electric charge, challenging the conventional understanding of gravity as a purely geometric curvature of spacetime. By exploring the relationship between charge and gravitational behavior, the study proposes that gravity could fundamentally be an electromagnetic phenomenon. The paper combines theoretical analysis and experimental design to test whether charged objects exhibit measurable differences in weight compared to neutral ones. If validated, this approach could offer a unified view of gravity and electromagnetism, providing a new perspective on the nature of gravitational force and its origin at the atomic level.
No, it would imply a violation of the equivalence principle, which means that there exist fields, in addition to the metric, that define the geometry of spacetime and, thus, couple to the electric charge of the constituents of matter. It is possible to classify such theories (that involve, typically, additional scalar fields, so-called ``scalar-tensor theories'', or, also, more generally, vector and spinor fields, so-called ``supergravity theories'')
and the corresponding experimental signals are studied as a matter of course as backgrounds. For the moment no such violations have been measured.
