I'm just stating the double slit experiment as explained in that PBS video and others and curious about seeing an actual picture. My only suspicion is that no

  Ah, well the video is about electrons, and it's somewhat more plausible to "observe" them going through one slit or the other, since they will emit an electromagnetic field. There do seem to be such recent experiments, for example https://phys.org/news/2011-01-which-way-detector-mystery-double-slit.html https://phys.org/news/2011-01-which-way-detector-mystery-dou...

    That's a great link! Thanks! Derp, sorry... Electrons and photons are completely different types of particles. I'm getting things mixed up. And I had just skimmed that video again! I need to pay attention. Still, I would have loved for the authors of that paper to get a pic of the setup and results on the computer monitor next to it or something. Also, isn't this stuff fundamental to theoretical quantum encryption? If we try to observe information as it flows by, we always alter it in detectable ways because of the observation effect? I think? (In some ways it's absurd that here we are, everyday people, chatting away trying to get a mental hold on the weird, abstract yet fundamental way the universe works, as dreamed up by literal scientific geniuses a century ago. But in reality, getting a general grasp of this stuff is knowledge you need to have in so many fields, from suburban electrician to anyone working in high tech. Crazy.)
