Gravity and Relativity from SU(2) Phase Dynamics on a 4D Hypersphere

I present a unified geometric description of gravity and special relativity based on the SU(2) phase structure over a compact 4D hypersphere S3 [1,2]. Mass and gravitation are modeled as distortions of global SU(2) phase alignment. I derive Newtonian gravity, establish a natural origin for the constancy of the speed of light, and show how Lorentz symmetry emerges from hyperspherical constraints. This approach circumvents the need for spacetime curvature and offers a new route to gravitational phenomena.
