Unified Interpretation of Neutrino Essence and Its Various Physical Puzzles ——Based on the First-Principle Unified Theory of Light Strings (Final Revised Version)

A series of physical puzzles concerning neutrino mass origin, oscillation behavior, interaction characteristics and intrinsic chirality cannot be self-consistently explained by existing mainstream physical theories. Based on the First-Principle Unified Theory of Light Strings, this paper establishes a complete physical model of neutrino topological structure, formation mechanism and evolutionary behavior, uniformly interpreting neutrino mass origin, near-light-speed propagation, flavor oscillation essence, chiral characteristics and ultra-strong penetration from first principles. It is proved that the three observed neutrino flavors are only the limitation of current detection technology, and more intrinsic flavor states are theoretically allowed. This theory does not rely on experimental numerical fitting and has complete logical self-consistency and scientific falsifiability.
