Evidence for 5.9-Year Temporal Structure in Hubble Constant Measurements: A Potential Resolution of the Hubble Tension

This dataset contains the complete analysis demonstrating the discovery of a 5.90 ± 0.28 year periodic oscillation in Hubble constant measurements, matching exactly the period found in gravitational constant G variations (Dindar 2025, DOI: 10.5281/zenodo.17281428). KEY FINDINGS:- Period: 5.90 ± 0.28 years (H₀) vs 5.9 ± 0.5 years (G)- Amplitude: 2.34 ± 0.41 km/s/Mpc - Significance: p < 0.001- Impact: Resolves the Hubble Tension as temporal sampling effect The analysis of 47 high-precision H₀ measurements (1998-2024) reveals that CMB-based measurements systematically sample oscillation minima while local measurements sample maxima, separated by π radians phase shift. TESTABLE PREDICTIONS:- Next CMB minimum (2026): H₀ = 67.8 ± 0.5 km/s/Mpc- Next local maximum (2027): H₀ = 73.2 ± 1.0 km/s/Mpc This discovery transforms the Hubble tension from a cosmological crisis to a temporal phenomenon requiring new observational strategies.
