👉 Post-hoc light particles, often referred to as "ghost particles" or "virtual particles," are theoretical entities that emerge from quantum field theory but are not directly observable with current technology. These particles arise from the probabilistic nature of quantum mechanics and the principles of superposition and entanglement. In specific contexts, such as during particle interactions in high-energy physics experiments, these particles can appear and disappear without a trace, only to reappear under different conditions. They are not "real" in the classical sense but play a crucial role in explaining phenomena like the Casimir effect and the behavior of photons in quantum electrodynamics. While they cannot be directly postulated as tangible entities, their effects are observable and measurable, making them a fundamental part of our understanding of the subatomic world.
