A Conceptual Reinterpretation of Cosmic Redshift: Understanding Wavelength Elongation via Light Diffusion

This work presents a conceptual model that reinterprets cosmic redshift, traditionally regarded as evidence of spatial expansion in standard cosmology, as a process of light diffusion. By considering statistical broadening in the energy distribution of photons during long-distance propagation, the elongation of wavelengths (redshift) can be explained without invoking spatial expansion. The model does not aim to refute existing theories, but rather provides an alternative conceptual framework to understand observational data. It emphasizes interpretative freedom in cosmology, suggesting that cosmic phenomena may also be viewed through the intrinsic properties of light, opening potential new perspectives on the understanding of the universe.
