This paper presents a comprehensive unification of gravitational and electromagnetic phenomena through the introduction of spin as the foundational property of spacetime fabric. Building upon the ΛCGF1 framework and the Spin Metric2, we demonstrate that angular momentum is not a secondary effect, but the primary generator of charge, magnetism, mass, and temporal progression. The subquantum grain lattice, when compressed and twisted under gravitational tension, naturally gives rise to electric and magnetic fields through rotational deformation. Matter itself emerges as a stabilized torsional structure—a standing wave of curved tension. By reframing all field interactions as the result of rotational strain within the compressed matrix of spacetime, we reconcile curvature (General Relativity) with field emergence (Electromagnetism) in a single dynamic principle. This work completes the Grand Unification long sought by Maxwell and Einstein, revealing that at the heart of every force and every form lies the same forgotten truth: Spin generates everything.
