Part 7/9:
What complicates the scenario is that photons can be directed to various detectors, and the type of pattern observed can seem to change based on where the photons land. The way this experiment is presented often leads to the impression that the resulting patterns at one detector could change based on decisions made regarding other detectors, thus implying that present actions influence past outcomes.
Debunking Misleading Perceptions
When examining the outcomes from the detectors, it appears that photons that reveal which path they took yield a spread-out pattern, while those where path information is erased show an interference pattern. This lead to the erroneous conclusion that the choice of measurement at one point affects measurements taken at an earlier time.
