This paper presents the third major instalment of the DoIH XV series within Informational Cosmology. Here, redshift is reinterpreted not as evidence of expanding space, but as the gradual informational fading of photons as they travel through a universe increasingly dominated by dark-energy equilibrium fields. Building on the foundations of Papers 1 and 2, this work introduces a non-expansion explanation for cosmological redshift that arises naturally from the Hunt–Lyra Informational Luminosity Law. As photons propagate across cosmological distances, they lose informational structure into the surrounding equilibrium medium, causing a systematic drift toward lower frequencies. This single mechanism unifies: the observed redshift–distance relation long-wavelength background overpopulation CMB smoothness and depth limitations high-redshift spectral anomalies the apparent age and maturity of early galaxies The result is a coherent and testable alternative to expansion cosmology, grounded in the informational identity Phi R = E + I and the physics of diffusion rather than spacetime stretching.
