Thanks Nugatory, BvU, DrChinese, and PeterDonis , I understand what you are saying now. In this thread, you all seem to be saying that the wave collapses at the point where the photon has an INTERACTION (impact) with anything else. It seems like all of the "Discovery Channel" type...

Thanks PeterDonis, You said : "Won't matter. The sensor inside the camera that detects photons will still undergo an irreversible change, and that's sufficient to "observe" the photons coming through the slits." Maybe I am relying too much on a simplistic explanation of the "double slit...

Thanks DrChinese, Please see my recent post (above) and give me your feedback (thanks!). In my original "thought experiment", it would NOT be possible to determine the path because the recorded data had been permanently destroyed (albeit, after the fact). What if you change my original...

Thanks BvU, I am not sure of your answer. Are you saying that permanently destroying the recorded activity before it is observed by humans makes no difference? I am trying to identify what amounts to an "observation" of activity. Is it human perception? I have read that if the "cameras" at...

Thanks in advance to all who reply. Forgive me if this naive, I am not scientifically inclined, but I am VERY curious. After re-watching a documentary on quantum physics, I have a "thought experiment" that I would like feedback on. Maybe this experiment (or something like it) has already been...
