We show that a single topological ansatz — spacetime near a gravitational source has the structure S¹ × S² — reproduces all classical tests of general relativity, explains galaxy rotation curves without dark matter, and predicts the Schumann resonance from pure geometry. Extending S² = CP¹ to CP² at nuclear scales, the full Standard Model gauge group U (1) × SU (2) × SU (3) emerges from topology alone. The Euler characteristic χ (CP²) = 3 predicts exactly three fermion generations, and the mass ratio mₚ/mₑ = χ (CP¹) × χ (CP²) × π⁵ = 6π⁵ matches observation to 0. 002%. The inverse fine structure constant 1/α = 4π³ + π² + π matches to 0. 0002%. No free parameters are adjusted. Seven falsifiable predictions distinguish this framework from standard physics.
