Leynstrinsic Field Theory: Paper 6 - Cosmological Evolution and the Null Smooth Universe in Leynstrinsic Field Theory

This paper develops the cosmological framework of Leynstrinsic Field Theory, describing the emergence of spacetime geometry from an underlying connectivity field. Cosmological evolution is interpreted as a dynamical relaxation process in which connectivity organizes into stable geometric configurations, producing smooth expansion without requiring a singular origin. The early universe is modeled as a pre-geometric phase with reduced effective dimensionality, leading to the Null Smooth Universe interpretation. The resulting framework reproduces large-scale cosmological behavior while providing an alternative foundation for early-universe physics and spacetime structure.
