what about it? In quantum mechanics, an observer is anything that interacts with the quantum system in question, and an observation, or measurement, is that interaction.
That is debatable. If a worm observes something would that change it? Or if a man observes? Maybe you don't know!
The key words there are, 'observed reality'; the way you make measurements affects what you see.
I would think that infers observed by man.
For example, depending how your measurement equipment is configured, you might see a something that behaves like a particle, or something that behaves like a wave. The measuring apparatus is part of the system and affects how it behaves, which affects the results you see.
Man sets it up, and man observes. You can't take the experiments to mean much without man! Name one experiment that leaves man out?? Ha. Therefore man is in all experiments, so any observation means man observes. If, therefore the observation can affect reality, that means only man (or God, or angels) observing affects reality...unless and until you get some empirical data or experiment that suggests otherwise.
In quantum systems, the sort of information you can obtain about the system affects how it is observed to behave.
So it is flexible, and subject to probability, and can behave more than one way! All affected by the observer which is man! Name any other observer?
If you set up your equipment to detect which path a particle takes through an experiment, it will behave like a particle taking a particular path through the experiment;
Right, if a MAN sets it up, we will observe stuff. Now if we were right with God, I bet we would observe a lot more. Not only that but we could affect much more and determine reality a lot more. The quantum level then becomes a mere tool, that can be used to do what our free will wants. Free will would determine the 'probability'. The only reason it now seems strange and murky, and subject to 'probability' could be because right now, we are out of sync with God's creation, so do not now know it will turn out?
otherwise, it will behave like a probability amplitude wave, taking all possible paths, until it finally interacts (e.g. is detected) at some location, the probability of which is governed by the probability amplitude at that point.
In other words, maybe, if we do not pray, or are not right with the creator, the universe will go merrily on it's way. No surprise there! The exciting thing is that we can affect reality and the outcome, especially when we get out from under this present sin state.
