Electromagnetic Origins of Gravity and Inertia in Classical Systems

This paper proposes that all classical mechanical and gravitational effects in ordinary matter arise from electromagnetic interactions. It argues that mass, inertia, contact forces, and spacetime curvature reflect the energy and structure of electromagnetic fields generated by charged particles. Two postulates support this view: (1) the electromagnetic field fully accounts for the stress-energy content responsible for all classical mechanical behavior, including inertia and contact forces, and (2) fluctuating charges in ordinary matter generate both radiation and relativistic effects, even in electrically neutral systems. The theory establishes a formal correspondence between gravitational and electrostatic potentials and shows that geodesic motion and time dilation arise from gradients in electromagnetic field energy. The apparent weakness of gravity is explained as a statistical average over countless small-scale interactions. Within classical regimes and for ordinary matter, this framework eliminates the need for additional forces by unifying all observable motion under electromagnetism and identifying the electromagnetic field as the physical background of spacetime.
