I see, and I am happy you've finally accepted common-sense defnition of reality as something detectable.ok, to me a violation of causality is an influence that can affect the past in reality,i hope you see the confussion here.
I also hope you see that Wheeler experiment does not influence past physical reality (in a meaning you've just accepted) and thus doesn't violate causality.
Oooch? Are there people who do not believe in ghosts, invisible dragons and photon paths? Yes. They are. Not many, but there are some.also is there a view in which the present does not affect the past?
