The "Inside of the Universe" in the Light Universe Theory -- A Cosmological Model That Does Not Assume Isotropy of the Entire Universe --

This paper introduces the concept of the “inside of the universe” within the Light Universe Theory. Instead of assuming that isotropy observed on large scales necessarily extends to the entire universe, the model defines the region in which isotropy is established as the “inside of the universe.” This distinction separates observed isotropy from the global structure of the universe and provides an alternative framework for considering the origin and structure of the universe.
