This work presents a conceptual reinterpretation of distant galaxy redshift and cosmic visibility based on the Light Universe Theory. Unlike standard cosmology (ΛCDM), which estimates galaxies at redshift z 10 to be roughly 46. 5 billion light-years away, the Light Universe Theory constrains the maximum distance to approximately 20 billion light-years, given the cosmic age limit and assuming cosmic expansion at the speed of light. The early universe exhibits a sharp increase in redshift, resulting in a convex, steep distance--redshift curve. Observational data are included illustratively, with emphasis on conceptual differences between models. This draft provides an English-language, LaTeX-ready version suitable for future figure integration and further exploration.
