Wheeler's delayed choice experiment is a variant of the classic double slit experiment for photons in which the detecting screen may or may not be removed after the photons had passed through the slits. If removed, there are lenses behind the screen refocusing the optics to reveal which slit the photon passed through sharply. How must this experiment be interpreted?
- Does the photon only acquire wave/particle properties only at the moment of measurement, no matter how delayed it is?
- Can measurements affect the past retrocausally?
- What was the history of the photon before measurement?
- What are the beables before the decision was made?
