rhon

Rhon is a term used in speculative physics and in science fiction to denote a hypothetical fundamental particle or energy form. In real-world discourse, rhon is not part of the established standard model, and there is no experimental confirmation of its existence.

In theoretical model-building, rhon is sometimes described as a neutral particle that mediates a new short-range force or as a portal to a hidden sector. Depending on the model, rhon may be a boson or a fermion, possess a small mass, and couple weakly to standard-model particles. The lack of experimental evidence means that current data from high-energy colliders, precision measurements, and astrophysical observations place upper limits on its coupling strength and/or constrain its mass scale, rather than firmly identifying a definite value.

Outside physics, rhon appears in fantasy and science-fiction contexts as an energy source or mineral with unique properties, or as a fictional deity or sigil. In such settings, rhon-powered technologies or rituals often drive plot elements and worldbuilding, with the term treated as a generic sci-fi flavor rather than a specific real-world entity.

Etymology and usage: rhon is a constructed term in many works, sometimes chosen for its neutral phonetics or used as an acronym. There is no single canonical definition, and different authors may assign disparate properties.
