Non-Equilibrium Unified Field Theory Based on the Principle of Spatial Symmetry Maintenance: 3D Extension, 4-Vector Mass, and d'Alembertian Formulation

This study presents a unified non-equilibrium equation that defines the four fundamental inter- actions as a single restorative process of spatial symmetry. By extending the previous 1D model into 3D space and redefining mass as a 4-component information vector m = (m, 0, 0, 0), we ensure mathematical consistency across dimensions. Furthermore, the self-energy density term is defined using the inner product y·y, effectively coupling directional force with isotropic energy. By elevating the field operator to the d’Alembertian (□), we formulate a dynamic equation that describes the propagation and attenuation of spatial distortions as waves. This theory resolves the cosmological constant problem and achieves full integration with Maxwell-type equations based on mass density
