But does the act of observation change the results of the observation, per Shroedinger? Theoretically, if "reality" changed as we changed location, then the "new" reality would not even be observable to us. Or more precisely, since there would be nothing to contrast it with, the DIFFERENCE would not be noticeable. I can't imagine there's some physical threshold beyond which Reality A becomes Reality B, so the change would have to be gradual as A faded out and B emerged. What do physical laws become in the transition?
I don't know that this is a straightforward Shroedinger case, but it does pose some intriguing questions.
