This paper explores a novel distinction between photons and neutrinos based on their interaction with spacetime fabrics in a holographic universe [1][2]. While photons are known to propagate universally and act as carriers of information across intersecting holographic layers, we propose that neutrinos traverse a distinct and isolated spacetime fabric. Unlike photons, which copy and broadcast their quantum state to multiple observers and regions, neutrinos retain their state within a localized domain, only interacting when another particle’s spacetime address aligns precisely with their own. This framework explains the elusive nature of neutrinos, their weak interaction cross-section, and their negligible role in quantum entanglement. By introducing the concept of "holographic address resonance," we provide a new geometric basis for understanding weak interactions, neutrino oscillations[5][6], and the possible link between hidden sectors and the structure of spacetime. The proposed model complements existing interpretations of the Standard Model while opening avenues for a deeper unification of quantum mechanics and spacetime geometry.
