@metal-brain saidWhat do you plan to do with the theory? In the end issues of ultimate truth and priesthood are just a fight over undeserved status, the worthwhile purpose of a theory of nature is to alter nature to serve our purposes. We use the theory to make things that improve our lives, hopefully, but these things all exist for our use and have no purpose if we are not there to use and in using observe them. So, if there is an effect that depends on the presence of an observer, then we might not have found ultimate truth, but at least we can do something with it. The converse case I mentioned earlier is useless.
"However, if there is an effect that depends on the absence of an observer then it is outside physics."
How do you know it is not the other way around? If an effect depends on an observer then perhaps that is outside physics. Observing changes the result, right?
