Three Native Generation Mechanisms and Full Life Cycle Evolution of Neutrinos

Existing neutrino physics faces several open-ended challenges: the physical origin of exactly three active neutrino flavours, the large propagation differences between photons and neutrinos generated from the same cosmic perturbation events, and the under-studied behaviour of cosmic low-energy background neutrinos. In addition, several commonly-seen natural optical phenomena are often given oversimplified interpretations. This paper presents a conceptual qualitative framework: three mutually orthogonal cosmic perturbation modes may give rise to three native neutrino flavours. An alternative medium-driven flavour-oscillation picture is offered as a possible complement to the standard-model mass-mixing description. A full life-cycle sketch for neutrinos is outlined. Through the chains of electron-positron annihilation and Compton scattering, a unified Cherenkov-radiation-based mechanism is proposed to interpret five categories of optical phenomena and to reconsider four widespread optical misunderstandings. This framework attempts to connect high-energy and low-energy neutrino behaviours and supplies test-inspiring qualitative viewpoints for astronomy, biophotonics and atmospheric-physics communities.
