A group of particles can interact without it counting as an observation which is why I mentioned entanglement. https://en.wikipedia.org/wiki/Quantum_entangleme

- username90 7y agoParticles can entangle when they interact, ie they go from not sharing a state to sharing a state. Your link states that wavefunction collapse is random and can thus not be used to communicate information, it doesn't say anything about interactions resulting in shared state.
- atq2119 7y agoI would bet ssijak thinks in MWI, where observation is not a separate thing from interaction and there is no such thing as "counting as an observation" in physical reality. The "observations" that other interpretations cause endless confusion about are simply interactions between the observed system and the observer, but "observed system" and "observer" are concepts without a corresponding physically reality. They're simply labels assigned by humans.
- solinent 7y agoNote that there's no way to observe a particle without some form of entanglement, though.
