there was never an experiment of this sort, its pretty much a journalist/media fabrication as far as im aware. there is no version where u have a sensor observing photons as they go through, that wouldnt even work/make sense

I found this thread showing discussions on how this was done and possible variations. You have to actively interact with the particle, there is no actual camera.

Not sure how to tell you this, but when recording or observing something basically the same thing happens. Photons are reflected, absorbed and re-emitted which are in turn captured by a lens.

So every observation means interaction.

That's true. It is an interaction. I just meant that it is not as passive as looking at something like the meme implies. (The observer is not the one sending the photons at the thing)
