Entropic Cosmology without Expansion: A Resolution-Shift Model for Apparent Cosmic Acceleration

We propose a novel cosmological model in which the observed cosmic acceleration is not caused by the expansion of space, but by an entropy-driven shift in the observer’s information resolution. This "resolution-shift cosmology" replaces spatial expansion with a logarithmic entropy effect: **f(z) = α log(1 + β z)**, fitting the Pantheon+ supernova data with high precision. Key contributions include:- Elimination of dark energy as a necessary component- High accuracy reproduction of ΛCDM distance modulus with residuals within ±0.1 mag- Physical interpretation based on quantum/statistical limits on resolution- Simplicity, falsifiability, and information-theoretic clarity We include four figures (model curve, comparison with ΛCDM, residuals, and parameter table), and an extended discussion on the physical motivation. This work opens a new paradigm where the illusion of expansion arises not from geometry—but from **information loss at cosmic scales**.
