nuorien
Nuorien is a term that appears in speculative physics and science fiction to denote a hypothetical elementary particle or field that interacts very weakly with known particles. In many models, nuorien is imagined as a boson associated with a new gauge symmetry in a hidden or dark sector, potentially acting as a mediator of a fifth fundamental force. The particle is typically conceived as light, with a mass from sub-eV up to keV, and with couplings to standard-model matter far weaker than the weak interaction.
Its interaction with ordinary matter is often described through portal mechanisms, such as kinetic mixing with
Experimental searches have not observed nuorien-like particles, and existing bounds from laboratory, solar, and cosmological data
In popular science and fiction, nuorien is sometimes invoked as a mechanism for dark radiation, anomalous energy
