But if you put a detector by each slit and measure which one each photon goes through, then the photons do have to behave like particles. They aren't constrained to acting like a particle. But since photons are quantum objects, that doesn't matter. In this case, there is no way to tell which slit the "particle" photon went through. Left to their own devices, the photons take on a wave behavior, spreading through both slits and interfering with themselves to create a rippled pattern of light and dark on a more distant screen. Shine a beam of photons against a barrier with two slit openings. Light exhibits the characteristics of both a wave and a particle, and this changes depending on whether or not it is measured. The present can change the past (), or Schrodinger’s cat brought back to life.
