existerons

Existerons are hypothetical quantum entities posited in speculative theories that link reality itself to a measurable parameter called existence. They are described as excitations of a proposed existence field permeating spacetime, distinct from standard particles and fields. In this view, physical systems possess a degree of ontologicality that can be modulated by observation.

The term derives from the Latin existere, “to exist,” and appeared in discussions on ontology in physics. The concept is not widely adopted in mainstream physics and remains primarily a topic in thought experiments and fringe theoretical work.

Proposed properties include neutrality and extremely weak interaction with known forces; existerons would not carry energy or momentum in the conventional sense. They are described by an existence density or ontological amplitude that could influence decoherence, state selection, or the apparent stability of configurations, without exchanging energy.

Status: There is no experimental evidence. Critics argue the idea straddles metaphysics and physics and lacks falsifiable predictions. Proposed tests include ultra-precise interferometry to search for anomalous decoherence or cosmological constraints on background existence fields; so far, results are inconclusive.

In philosophy of physics, existerons are used as a thought experiment about the role of observation and existence in theory, but the idea remains fringe and unsettled. See also quantum ontology, measurement problem, and decoherence as related topics.
