“Suspect the stone, water,trees are there whether we are here to ‘experience’ them or not...”
Well, according to some interpretations of quantum physics (mainstream interpretations, not quack theories), an observation is required to “resolve” anything from simple quantum probabilities to the apparently deterministic universe that we perceive. We do know with a certainty that, at the atomic/subatomic level at least, things behave quite differently depending on whether we are observing them or not.
“things behave quite differently depending on whether we are observing them or not.”
The “interference” of OBSERVING is a physical event and of course has consequences. Also “observing” requires a sentient being to do so.( or at least an item made by someone for measuring an event)) The actual event, say the collision of atoms occurs whether ‘observed’, OR NOT..
