Lmax_v11: A Photon‑Stretch Framework for Cosmological Redshift and Distance

Lmax_v11 presents a photon‑stretch reinterpretation of cosmological redshift, dimming, and distance, replacing spacetime expansion with the geometric stretching of light—the medium through which the universe is observed. The framework treats wavelength dilation as a distance‑dependent evolution of photon energy density along a null geodesic, governed by the affine‑parameter limit Lmax(Φ, B). This paper includes the full theoretical structure, plain‑text field equations, and detailed explanations of the model’s geometry, lensing behaviour, and survival probabilities. It also provides JWST Cycle 5 observational predictions, including a static galaxy shell, diffuse re‑emission haze, and affine‑parameter exhaustion signatures. The work offers a unified, testable alternative to metric expansion cosmology grounded entirely in photon behaviour.
