    Naw. “observing” doesn’t mean, a human looks at the data. It means, we force the particle to be in one place on a quantum level. the word “observation” is overloaded in some sense

    “Observation” or “measurement” actually means interaction. We literally can’t measure anything without interacting with it. If you place something at the slits which is able to detect a photon going through, it can only do so by interacting with it.

    The common way seems to be that the passing particle induces a tiny electric current in a wire loop. Obviously, that takes energy away from the particle (that energy is now in the movement of one or more electrons in the wire). And that means, its wave function in that very moment is one locational probability of 1 - it is collapsed.

      Yeah no. Many scientists are crawling all over YouTube on this one and explaining it the other way. That it even reversed the results when going back to observe it. Like changing time. I don’t see any of you people calling that shit out as hard as you’re doing here.

      It’s funny cuz even if someone states they know exactly what’s going on here (as if everyone else is stupid and misunderstands it) it becomes the biggest heated debate between all the eggheads in the room.

      no one agrees on what is going on here.

      Being a rando online Calling everyone else stupid or referring to a deeply debated subject such as this one is just simply misunderstood doesnt make you the smartest person in the room. It certainly doesn’t make you appear to know what is going on to explain it yet again in yet a different way that contradicts scientists who do show their face and names who have explained it the other way.

      My understanding is that the tools that are used to observe it cause the wave function to collapse. Like how putting a thermometer into meat to check the temp makes a little hole.

        Yep! The only way to “see” a photon is to actually absorb it. You can’t just detect it as it goes by, it has to be absorbed and reemitted, and that has an effect on it.

        I mean, thats also how we got weird pseudoscience about how the universe shifts around our consciousness.

        Its usually not made clear in school that things can only be measured by touching it or bouncing something off of it. On the macro scale, looking at something doesn’t move the thing you’re measuring because you’re just capturing the abundant photons that are already bouncing off the thing in the billions per second. On the quantum scale, looking at something involves shooting particles at the thing, which is often comparable to measuring how big a cat is by trying to bounce a kickball off it and measuring the angle it rebounds. It works, but you can’t expect the cat to continue behaving the same after being assaulted out of nowhere.
