The standard cosmological model (ΛCDM) faces critical challenges, including the Hubble tension,the vacuum energy catastrophe (10120 discrepancy), and recent JWST observations of mature galaxies at z > 10. We propose that these anomalies stem from neglecting the dynamical memory of thevacuum. We model spacetime as a Maxwell-type viscoelastic continuum governed by Kim’s Law:τ = C/H. By constraining the vacuum’s stored elastic energy to match the observed dark energydensity, we analytically determine the viscoelastic constant to be C ≈ 0.795. This framework yieldsthree transformative results: (1) The vacuum acts as a spectral filter, dissipating high-frequencyquantum fluctuations while storing only cosmological-scale deformation; (2) The viscoelastic delayextends the age of the universe to 16.55 Gyr, resolving the early galaxy formation crisis; (3) TheHubble tension is explained as a phase-lag effect. We further present specific observational predictions regarding gravitational wave memory relaxation and structure growth rates (fσ8), offering aclear path for experimental verification.
