This work proposes a fundamental transition in the early universe where the metric signature changes from Euclidean to Lorentzian, triggered when vacuum energy exceeds a critical threshold. By introducing a continuous energy flux (₅₋₎ₖ) from the Euclidean sector, we present a unified framework to address major cosmological anomalies. Key highlights of this upload: Hubble Tension: Resolution of the discrepancy between H₀ 67. 4 and 73. 1 km/s/Mpc through a dynamical temporal channel. S₈ Tension: Suppression of matter growth via quadratic viscosity = ², where = 3/8. NANOGrav Validation: Consistency with the stochastic gravitational wave background (SGWB) with a spectral index 3. 15. The upload includes the full manuscript (PDF), Python source codes for figure generation, and Monte Carlo simulation data for statistical validation.
