ABSTRACT Over the past century, modern physics has been bifurcated into the theory of relativity explaining the macro-world and quantum mechanics dealing with the micro-world. In doing so, it has forfeited mechanical causality, relying instead on mathematical probabilities and geometric optical illusions. This paper meticulously identifies the epistemological blind spots and voids of conventional physics and proposes 'Jung Sung-mo's Grand Unified Dynamics,' which penetrates all forces and motions of the universe with a single, overarching mechanical principle. First, this study establishes the 'Theory of Absolute Intrinsic Physical Metric Relativity,' which posits that every object in the universe independently possesses its own intrinsic unit time (T) and unit distance (L). By introducing the independent metrics (Tc, Lc) of a 'Third-party Omniscient Observer ( C)' into the formulation, we present an algebraic formula for deriving relative velocity, thereby completely and mechanically dismantling the inherent contradictions and the Twin Paradox of Einstein's Special Theory of Relativity. Second, the reality of quantum phenomena, previously dismissed as mere probability clouds, is explicitly elucidated through a novel three-step verification framework: Theoretical Formulation → Algebraic Equation Derivation → 3D Parametric Simulation Verification. Within the Dynamic Field formed by the intrinsic motion of particles within the Static Field lattice medium, the mechanical cumulative density of multi-dimensionally superimposed and rotating particles is mathematically formulated. In particular, it visually and dynamically demonstrates via a computer simulation (Appendix A) that the geometric configurations of s, p, d, f orbitals—long considered an enigma in quantum mechanics—are not mathematical probability functions, but rather the pure mechanical outcomes of a 'Teardrop Envelope Trajectory' designed for friction avoidance between particles and a 'Surface of Revolution Scanning' across multiple planes. Ultimately, this study declares a paradigm shift toward a grand unified physics that strips away Einstein's spacetime curvature and Schrödinger's probabilistic illusions, thereby fully restoring the authentic mechanical causality of the Field that bridges the macroscopic and microscopic realms of the universe.
