A Global Rigid Proper-Time Clock from an Adelic Scalar

Abstract | A single spacetime-dependent scalar π(x^μ) taking values in the restricted adeles ℝ × ℤ₂ × ℤ₃ × ℤ₅ × ℤ₇ × ℤ₁₁ with six axioms defines a global rigid proper-time clock π_real that is exactly synchronized for every observer in the universe. The same construction derives: - the non-abelian gauge sector SU(2)_L × SU(3)_c - the exact Standard-Model chiral spectrum with three generations and three right-handed neutrinos - the observed Yukawa hierarchy - Λ = 0 exactly - a synchronous gauge (lapse = 1, shift = 0) with no coordinate gravitational time dilation The prime bundle (5,7,11) defines the next transcendent irrational after π: the minimal quadratic core τ = √33 in [5,6) and maximal unit ε = 6 + √33 (gap shift δ = 6). This reproduces the CKM matrix magnitudes within experimental error (e.g., |V_us|≈0.2265, |V_cb|≈0.0414, |V_ub|≈0.0037, Particle Data Group 2024/2025) via Diophantine ansätze derived from dimensional indexing and continued fraction convergents. U(1)_Y coupling and dark-matter abundance remain measured inputs; hypercharges and the Einstein–Hilbert coefficient are derived in Papers II and III.
