👉 Closure, in the context of light particles (photons), refers to the phenomenon where photons exhibit behavior that seems to transcend their classical wave-particle duality, particularly in how they interact with matter and each other. When we say light particles have closure, it means they can maintain a certain level of coherence and continuity in their interactions, even when seemingly isolated or disconnected. For instance, in a process like stimulated emission, a photon can trigger the emission of another photon of the same energy and phase, effectively "closing the loop" on its initial interaction. This closure allows photons to form stable, localized structures, such as in laser beams, where they maintain a consistent phase relationship over distance. Essentially, closure in light particles describes their ability to retain and propagate coherent properties despite potential disruptions or interactions with their environment.
