As far as I know, the detectors need to be able to interact with the photons, which redirected(or consumed) the outer “branches” that were landing in the outer slits. This left the only two slits untouched. It shows the fallacy of using detection equipment without considering their impact on the environment or experiment, especially when the extremes of our physical world are being tested. In the experiment, the detection equipment, or sensors, were placed in the two slits.
Thanks for this. Was getting tired of seeing people claim that our eyeballs change the photon path somehow and was getting ready to type.
For anyone familiar with circuits, it’s the same concept as understand why connecting an ammeter or voltmeter changes the value you measure. That is, a miniscule resistance must be attached in series or in parallel, respectively, to observe/measure the current or voltage, which inherently changes the current or voltage.
