This study explores a conceptual connection between Light-Cosmos Theory and the Black Hole Universe Hypothesis by assuming that photons possess an intrinsically tiny mass. Light-Cosmos Theory postulates that photons dominate the early universe, while recent cosmological discussions suggest that our observable universe may exist within the interior of a massive black hole. By introducing a micro-mass for photons, this work demonstrates that: Mass conservation can be universally applied, including during photon emission and matter formation. The transition from light to matter can be understood as a continuous manifestation of photon mass. Gravitational contributions from light naturally shape the internal dynamics of a universe residing inside a black hole. Observational constraints, such as the constancy of light speed, remain unaffected. This framework offers a unified and intuitive perspective on the interplay between photons, matter, and the large-scale structure of the universe, providing a conceptual bridge between photon-based cosmology and black hole universe models.
