Elastic Field Series – Part II: The Structure of Matter and the Dynamics of Resonant Motion

This second part of the Elastic Field Series develops the idea that matter arises as a stable standing resonance of the elastic field. The work examines how localized oscillations of the vacuum lattice acquire persistence and inertia, forming the basis of physical particles. Motion is interpreted as a transformation of the internal wave geometry of matter — a shift from symmetric standing patterns to directed phase gradients that carry kinetic energy. This establishes a unified picture where mass, momentum, and motion are different manifestations of the same elastic process.
