    It’s really frustrating that people who don’t understand this experiment have insanely taken into assume that a magic particle spell understands if a human being is watching or not.

      Perhaps it would be better to explain why instead of attempting a mic drop based on your superior knowledge?

      It’s called the observer effect, and it happens because:

      This is often the result of utilizing instruments that, by necessity, alter the state of what they measure in some manner.

      And particularly in the double-slit experiment:

      Physicists have found that observation of quantum phenomena by a detector or an instrument can change the measured results of this experiment.

      https://en.wikipedia.org/wiki/Observer_effect_(physics)

      So for anyone who wants to have a surface understanding of the observer effect, the wiki does a fair job of the basic explanation.

        I think the issue is that quantum mechanics is hard to popularize without leading people into wrong conclusions, pop science clickbaits make this worse.
        I find it easier to understand if you say that observing necessarily means there’s an interaction energy (for example a photon), otherwise no information can be retrieved, and however small that information retrieval energy is, quantum systems are so sensitive, that it is enough to modify their behavior.

      That’s not really it. You need something that measures the state of the electron. Merely looking in the direction is not enough. It has to be something that interacts with the electron.

      A camera alone isn’t enough. But light (eg photons) with enough energy should be enough. But then that energy will manipulate the electron. If you had a completely dark room and pointed a camera at the experiment it wouldn’t change anything.

      It’s kind of like having your cake and eating it too.

        Yeah, it turns out that slapping the electron around like with a big stick or whatever causes it to change its behavior, go figure! :-P

        So if we didn’t need light to see it then it would continue doing whatever it does?

        I wonder how the universe would look if we didn’t need light to see 🤔
