A New Theory on the Nature of Single-Slit and Double-Slit Patterns: The Photon Tremor Collision Scattering Theory (Revised Edition)

Traditional quantum mechanics explains single-slit diffraction and double-slit interference using wave–particle duality, claiming that photons exhibit both particle and wave properties and can produce self-interference to form light–dark patterns. This paper proposes a new theory: photons always move in uniform linear motion, accompanied by 360° omnidirectional, random, uncontrollable microscopic tremor during propagation. The patterns observed in single-slit and double-slit experiments are macroscopic phenomena formed by collision, reflection, and angular deflection of photons with slit walls due to their inherent tremor, followed by geometric amplification and statistical superposition of numerous photon trajectories. No patterns appear without a baffle because photons do not collide with any wall; no patterns appear with an overly wide slit because photons still pass through without touching the walls. Patterns emerge only when the slit is narrow enough to cause photon–wall collisions. When photons collide with atoms on the slit walls, electrons undergo energy level transitions and emit secondary light; superposition of secondary light from different directions forms alternating bright and dark fringes. This paper designs a carbon nanotube light-absorbing/non-absorbing control experiment and a receiver backplate distance variation auxiliary experiment, both of which provide quantitative and measurable evidence for the theory and form a complete logical closed loop, indicating that the wave–particle duality interpretation is untenable.
