"Photon Aging" versus "Space Expansion": A Meta–Monist Re-reading of Cosmic Redshift

We propose a paradigm shift: cosmological redshift as a manifestation of photon energy loss within the Meta–Monist tension field, challenging the space-expansion paradigm of ΛCDM. Recasting Friedmann equations in the geometry of the Chaos– Polytope, we identify |∇T|—the temporal component of the tension field with the Hubble parameter a/a ˙ . A dynamical drift of |∇T| mimics time–dependent dark energy, reproducing the DESI 2025 anomaly. We predict a novel z-dependent polarization twist in quasar light, driven by the Chaos–Polytopes polarization drift βp, and anomalous gravitational wave echo-delays, alongside signatures in supernova time–stretch, Tolman surface–brightness, CMB spectrum, and baryon acoustic oscillations. An experimental roadmap (2026–2030) tests universal β–drift, facet– linked surface-brightness suppression, polarization twists, and fibre–loop analogues, addressing critical hurdles to establish Meta–Monism as a viable cosmology.
