Recules

Recules are hypothetical excitations proposed in speculative physics to carry reversal energy and influence the temporal ordering of processes within a localized system. In several models, a recule is a particle-like carrier of a reversibility parameter that biases the sequence of microscopic events while preserving macroscopic conservation laws. They are typically described as boson-like, chargeless with respect to standard gauge charges, and weakly coupled to ordinary matter.

Various frameworks treat recules as information carriers in a hidden sector or as excitations of a dual field that interacts weakly with known fields. All share the idea that recules mediate short-range, time-symmetric correlations without enabling macroscopic signaling. Different models differ in spin, mass, and coupling, but commonly posit a localized, transient presence rather than a persistent particle.

Recules remain speculative and are not part of mainstream physics. There is no experimental evidence for them, and their compatibility with causality and thermodynamics is debated. They are often discussed as thought experiments or as hypotheses awaiting empirical tests, rather than established entities in the physical world.

In science fiction and speculative contexts, recules are used to explain retrocausal effects, reversible computation, or exotic energy transfers. They function primarily as narrative devices to explore time, information, and the limits of observation. See also retrocausality, quasi-particle, hidden sector.
