Hi, I've done a lot of personal research on the internet trying to understand what exactly is happening in this experiment but I keep seeing contrasting information about what the role of observation actually had on the experiment. What I understand is that when they try to figure out which slit the particles actually went through before they appear on the screen, the wave function collapses because the detectors use light to read its position and that affects the particles somehow. How do the detectors actually affect the position of the particle? Certain explanations like in this video assert that when the detectors were turned on but the data wasn't collected then the wave function still didn't collapse. He thinks its the fact that someone is consciously interpreting the experiment that affects the results. I'm pretty sure that's false but I really don't know why. Edit: Or do the detectors even affect the outcome? according to this video the delayed choice quantum eraser experiment proves that it wasn't the detector that collapsed the wave function. According to this article, "The big mind**** here is that an interference patterns appears even when the which-slit information is removed in the far future! It is as if the electron knows that IN THE FUTURE the information about which slit it went through will be erased, and decides to act differently in the present moment!" Does science have explanations for these phenomena other than the natural assumption that it must be the act of conscious observers affecting the results of the experiment?
