Unified Derivation of the Four Fundamental Forces in Quantum Spin Torsion Theory (QST v7): Framework and Preliminary Experimental Verification

Quantum Spin Torsion Theory version 7 (QST v7) unifies the four fundamental forces—electromagnetic, strong, weak, and gravitational—as emergent geometric effects from particle spin interactions with the spinor ether field (ΨSE) and fractal dimension gradients (∇ D(x)). This paper derives the QST unified force formula (F{ QST} = κ σ^2 (∇ D(x) × J{ SC})), showing its application to each force. Preliminary verification uses 2025 experimental data from muon (g-2), high-frequency gravitational waves, THz optics, and galaxy rotation curves, supporting the formula with deviations <1(σ).
