About mid-way through this video it is explained that the doubleslit experiment was conducted with detectors turned on but simply not recording data, the result of which was an interference pattern. The act of turning the recording component on caused the interference pattern to be destroyed. Two questions: 1. Was such an experiment conducted or is this a simplification of a different experiment 2. If the experiment was conducted as explained above, is the current explanation that the physical world can somehow determine whether or not data about certain events are being recorded? When the record button is pressed does some kind of force in the universe decide "this course of events will cause the path of the electron to be known, so the electron must go through one detector or the other". It seems this is the consensus, however I want to make sure I'm understanding the situation correctly.
