The issue is that you can’t detect photons without interacting with them.

Can't...So far, right? Like there hasn't been a method developed to somehow detect indirectly without interaction? I don't know enough about this to know how one might go about that, but I imagine those that know more might love to given whatever knowledge may be gained.

No. Can't. The only interaction sensors have is with particles. Photons usually. All things give off light but then measuring light itself, measuring is destructive.

Lol this guy still believes in particles

Ah! A field absolutist. Keep preaching, friend.

"Detecting" equals "interaction" in this context. You can't detect them without detecting them.

Although, given some further thought, isn't the double-slit experiment being discussed here sort of demonstrative of a "detection" without detection, i.e. the wave pattern vs. the particle pattern emerging after "detection/measurement/interaction"? Or am I misunderstanding it?

Is there another way they operate/appear outside of the wave-particle that eludes observation?
