Definition: Phelonions are a type of quantum field theory that describes a hypothetical structure of matter at the scale of atoms and subatomic particles. These particles, which have a fundamental charge called the "photon" (and are usually represented by the symbol p), can interact with other particles in such a way that they produce various types of radiation or light. This concept is based on the idea of a quantum mechanical model where the behavior of matter and energy is described using wave-like phenomena, rather than classical
