This paper introduces a theoretical framework in which all physical phenomena arise from the oscillatory interaction between two coupled dynamical fields: a time deformation field, and a space inertia field. These fields exchange energy through a closed system of evolution equations, forming the basis for a unified interpretation of mass, force, wave propagation, and field behaviour. In this model, mass is not fundamental but emerges from the confined energy of a stable time-space oscillator. Electromagnetic, gravitational, and thermal phenomena are shown to result from specific configurations of this coupling. Entropy is reinterpreted as the rigidity of proper time under motion, and heat as the irreversible dispersion of time deformation. The framework recovers known physical laws — including Newtonian mechanics, Maxwell’s equations, and Einstein’s relation — as limiting cases of the same underlying dynamic process. This approach offers a unified and mechanistic basis for classical and quantum behaviour, while suggesting new directions for modelling particles, fields, and energy transport at all scales.
