Part 1 The Non-Overlapping Domains of Quantum Mechanics and General Relativity

Abstract / Description This upload presents a theoretical argument concerning the relationship between quantum mechanics, general relativity, and the early-universe QCD confinement transition. It proposes that quantum mechanics and general relativity should be understood as applying to distinct, non-overlapping physical regimes rather than as incomplete descriptions awaiting conventional unification. The paper identifies the QCD confinement transition as a physical boundary between a pre-geometric quantum phase, in which smooth spacetime and classical curvature are not yet applicable, and a post-geometric relativistic phase, in which stable matter, spacetime geometry, and gravitational structure become meaningful. On this basis, the work argues that traditional unification programs may rest on the mistaken assumption that the two frameworks operate simultaneously in nature. Instead, it suggests that future theoretical progress may depend on studying the emergence of spacetime, the thermodynamics of early-universe phase transitions, and the conditions under which classical geometry arises from quantum-dominated states.
