Neutrinos as a falsifiability test for a Principle of Least Information framework with an optional 7D–2t Janus embedding

HighlightsNeutrinos as a falsifiability test for a Principle of Least Informationframeworkwith an optional 7D–2t Janus embeddingJames Antoniadis• We frame neutrinos as a high-leverage falsifiability domain for information-theoretic foundations.• A Principle of Least Information (PLI) favors minimal neutrino sectorextensions and sharp exclusion statements.• Light eV-scale sterile neutrinos are strongly disfavored; neutrinolessdouble beta decay is a decisive discriminator.• We map PLI expectations to the current experimental situation (oscil-lation, 0νββ, direct mass, cosmology).• An appendix sketches how the same constraints can be embedded in a7D–2t “Janus” geometry.
