Geometric Derivation of the Fine-Structure Constant α = 1/137.036 from TUM v0.12: Clifford Algebra Cl(8) with Rule C≠D

TUM v0.12: Derivation of the fine-structure constant α = 1/137.036 from first principles using Time-Unity Theory. Core result: α = Γ_eq/16π² where Γ_eq = 0.8470 derived from Clifford Algebra Cl(8) projection 8D→3D with Rule C≠D. No free parameters. Builds on TUM v0.11 geometric foundation DOI: 10.5281/zenodo.20450294 4 falsifiable predictions: 1. Hawking radiation +10-30% faster than GR 2. LIGO ringdown 1-5 kHz for BH 30-60 M⊙ 3. EHT shadow 3-8% larger than Kerr metric 4. Galaxy rotation curves without dark matter Author: Sebastián Berón, Independent Researcher, Argentina Date: 2026-05-29 License: CC-BY-4.0
