Visuma

Visuma is a term used in speculative cosmology and metaphysical literature to denote a universal substrate that pervades all levels of reality, encoding physical phenomena and conscious experience. It is not an established physical field in mainstream science, but appears in theoretical discussions and fiction as a possible unifying medium.

The term is a neologism that has circulated mainly in online forums, independent writings, and some science-fiction texts. It is sometimes described as the information-bearing layer that underlies spacetime, energy, and perception, and is sometimes contrasted with more conventional ideas like fields, particles, or spacetime.

In visuma models, reality comprises discrete information quanta embedded in a continuous substrate. Interactions are thought to arise from changes in the substrate, while observation or consciousness is sometimes said to influence the local visumar structure. Some writers distinguish micro-, meso-, and macro-visuma as hierarchical levels.

The concept has few if any empirical foundations, and is generally treated as a speculative or fictional device. Proponents use it as a heuristic to discuss quantum interpretation, cosmology, and the role of information, while critics point to a lack of testability and the risk of unfalsifiable claims.

Visuma appears in science fiction, philosophy discussions, and role-playing settings as a framework for exploring questions about origin, reality, and the relation between observer and universe. It functions as a thought experiment rather than a confirmed scientific field.
