Atomor

Atomor is a term used in speculative physics and science fiction to denote a hypothetical fundamental constituent of matter, conceived as a stable, neutral composite particle or bound state that could underpin alternative models of the atomic world. The word is not part of the standard model and has no confirmed experimental basis.

In speculative frameworks, atomors are imagined as bound states of more fundamental entities—sometimes called preons or novel constituents—held together by a binding mechanism beyond the strong force. They are typically described as electrically neutral, with theoretical mass ranges from sub-eV to multi-TeV, depending on the model. Interactions with standard model particles are assumed to be weak or suppressed, making direct detection challenging. Some proposals associate atomors with dark matter candidates or with portals between visible and hidden sectors.

Status and search: There is no experimental evidence for atomors. Theoretical models must satisfy constraints from cosmology, astrophysical observations, and collider experiments, including limits on self-interactions, stability, and production rates. Researchers explore indirect signatures such as missing energy, anomalous scattering spectra, or cosmological effects in the early universe.

In culture, atomor appears in science fiction and speculative essays as a device to discuss questions about the fundamental building blocks of matter and the potential existence of hidden sectors beyond the standard model.
