A Memorandum on Neutrinos in a Light-Origin Universe

This work is a conceptual preprint that explores the role of neutrinos in a universe whose origin is assumed to be light.Rather than taking the standard cosmological model or the Standard Model of particle physics as its starting point, the paper adopts a minimal set of assumptions and focuses on conceptual consistency and qualitative connections to observational facts. The central idea is that neutrinos can be interpreted as the first stable massive states emerging from a primordial light-like entity through irreversible cosmic expansion and redshift-related energy transformation.In this framework, neutrinos are not treated as particles created from nothing, but as manifestations of a change in the mode of existence of light itself. This manuscript is presented as a memorandum rather than a completed theory.Mathematical formalism and quantitative modeling are intentionally omitted, and several key issues are explicitly left open for future versions.The purpose of this preprint is to serve as a foundation for further conceptual development and discussion linking light, redshift, mass, and neutrinos within a unified perspective.
