A Unified Force Density Equation for Equilibrium in Nuclear Fusion Plasmas

Current theoretical frameworks for nuclear fusion often struggle to accurately describe plasma stability due to a reliance on classical mechanics, which formulates forces as discrete vectors (Newtons) or surface pressures (Pascals). This article proposes that such approaches are insufficient for describing the volumetric nature of fusion processes, where forces are distributed continuously throughout the medium. Drawing on the principles of the Navier-Stokes equation, which models fluid dynamics via force densities (Newtons per cubic meter), we argue that a similar continuum approach is required for the electromagnetic and gravitational interactions within a nuclear plasma. We identify a fundamental gap in current physics: the lack of a single equation that unifies mechanical, electric, magnetic, and gravitational interactions as volumetric force densities. This study derives and presents a novel "Electro-Magnetic-Gravitational Equilibrium Field Equation." By expressing all relevant forces—including inertia and gravity—as densities (N/m3), this equation provides a rigorous mathematical condition for fundamental equilibrium in nuclear fusion processes, offering a new theoretical foundation for confinement and stability analysis.
