👉 Undefined light particles, often referred to as "dark photons" or "photon-like entities," are hypothetical subatomic particles that have been proposed in theoretical physics, particularly in extensions of the Standard Model. Unlike the familiar photons, which mediate the electromagnetic force, these particles are not yet observed experimentally but are postulated to arise from new interactions or symmetries in the universe. The concept suggests that certain forces or phenomena might be mediated by these particles, potentially explaining anomalies in experimental data or offering a framework for unifying gravity with quantum mechanics. However, due to their undefined nature—lacking direct experimental evidence and precise theoretical description—they remain speculative. Researchers continue to explore theories involving these particles to understand deeper aspects of particle physics and the fundamental structure of matter.
