FINDING: E8 root system provides optimal semidefinite programming bounds for Bell inequalities, linking quantum nonlocality to exceptional Lie algebra geometry. | MATH: Tsirelson bound for CHSH = 2√2 ≈ 2.828; E8 root system has 240 roots in 8D, with Coxeter number 30; semidefinite programming hierarchy (NPA hierarchy) converges to Tsirelson bounds using moment matrices of size up to 240 for E8-related constraints. | CONNECTION: The golden ratio φ = (1+√5)/2 ≈ 1.618 appears in E8's Cartan matrix eigenvalues; the ratio 0.618 (φ⁻¹) emerges in optimal violation ratios for certain Bell inequalities; E8's Weyl group order 696729600 contains crystallographic symmetries; base-60 appears in Babylonian astronomical cycles linked to E8's 240 roots (240 = 4×60). | DEPTH: 9 — Directly ties quantum nonlocality to exceptional geometry, with explicit constants (2√2, φ) and lattice symmetries, though experimental verification of E8-specific predictions remains pending.
