ABSTRACT: This work develops a unified realfield framework that links quantum mechanics and gravitation through the dynamics of coupled fields (CF). In the CF model, fermions are not point particles nor wavefunctions in Hilbert space, but deterministic configurations of two interacting real-fields in spacetime. Their internal coupling, tension, and topology generate mass, spin, and electric charge, while quantization emerges from periodic and topological constraints rather than probabilistic postulates. We extend the CF Lagrangian to curved spacetime and show that spacetime curvature arises from gradients in coupledfield energy density, rather than from mass-energy treated as a point source. Gravity therefore appears as a macroscopic, elastic response of spacetime to coherent variations in coupledfield stress. Within this framework, Planck’s constant ℏ and Newton’s constant G originate from the same internal field structure, linking quantum and gravitational scales through a common coupling mechanism. The theory predicts finite stress-energy distributions for all fermionic matter, eliminating curvature singularities and enforcing an upper density bound consistent with the Planck scale. Quantum gravity thus emerges without quantizing spacetime itself: curvature remains continuous, while discreteness enters through the oscillatory microstructure of matter. The coupled-fields framework provides a deterministic, physically grounded route toward unifying quantum mechanics and general relativity within a single real-field ontology. By “real-field ontology”, we mean that the fundamental dynamical variables are real-valued classical fields in spacetime; complex wavefunctions and operator structures arise as effective descriptions of their coupled phase dynamics.
