Theory of the Absolute: A Geometrical Interpretation of Spin

Spin is one of the fundamental properties of elementary particles and plays a central role in quantum theory and the Standard Model of particle physics. Despite its fundamental role and extensive experimental verification, its physical origin remains unclear, and spin is generally described within the standard quantum formalism without an explicit geometrical interpretation. This work investigates the possibility that spin may be understood as a manifestation of an underlying geometrical dynamics within the framework of the Theory of Absolute (ToA). The analysis is based on a toroidal model involving two coupled periodic motions. It is shown that a simple coupling between the angular coordinates of the toroidal trajectory naturally reproduces several characteristic properties of spin-1/2 systems, including two spin orientations, the characteristic spin-1/2 behavior, and the requirement of a 4𝜋 rotation for complete restoration of the dynamical state. The model further leads naturally to the relation S=L/2, from which the experimentally observed value g=2 follows. The analysis is further extended by incorporating the local temporal dynamics of ToA. Applying the theory's relation between velocity and local time to the proposed internal motion leads to a natural limitation of admissible internal velocities. As the internal velocity approaches the speed of light, the rate of local time decreases toward zero, providing a self-consistent dynamical constraint on the internal motion. When applied to the electron as an illustrative spin-1/2 system, the model also reproduces the characteristic scales of the Bohr magneton and the reduced Compton wavelength. The results suggest that the Theory of Absolute provides a coherent framework for investigating a realistic geometrical interpretation of spin. Although the proposed model does not constitute a complete physical theory of spin, it demonstrates that several experimentally observed spin properties can emerge naturally from a simple geometrical structure combined with local temporal dynamics.
