Rotational Field Substrate Theory: unified field substrate model

I developed the Rotational Substrate Model (RSFT) to establish a unified physical framework where electromagnetism, inertia, mass, and relativistic effects are not independent postulates, but emergent properties of a single, continuous rotational medium. In this model, spacetime is filled with a physical field possessing intrinsic spin degrees of freedom, where electric charge is a topological spin defect and magnetic fields arise from organized lateral spin shear. By treating the substrate as a mechanical lattice—specifically a 13-point nodal truss—I can derive Maxwell’s equations and Lorentz symmetry from the underlying dynamics of spin and vibrational ripples rather than relying on abstract geometry. I transitioned the name from the Unified Field Substrate Model (UFSM) to the Rotational Substrate Model (or Rotational Substrate Theory) specifically to distinguish my hypothesis from other similar theories. While many "unified field" models exist, they often rely on purely geometric or gauge-based approaches. By emphasizing the "Rotational" nature of the substrate, I am highlighting the unique mechanical foundation of my work, which interprets fields as physically real rotational dynamics. This shift ensures my framework is recognized for its specific focus on spin-field dynamics and the localized energy states that define mass and inertia, separating it from more generalized or metaphysical "substrate" concepts. New version also contains properly rendered equations for professional reference.
