Only so long as there are -not- relativistic effects, which -do- happen
-any- time a photon is involved.
***Reality is -observer- dependent***
The major hole in -all- current QM systems is they do not take into
account relativistic effects. Which are required -any time- a photon is
involved.

The error in this approach is not into taking account the relativity of
the experiment. From the traditional approach we are testing the photon
with the instrument, -but- the photon is also testing the instrument.
How big is the slit -from the perspective of the photon-? In other words;
how big is the cosmos to a signle photon?
The answer is it has no dimension. Now since there is no time or distance
scale from the perspective of the photon exactly -what- is happening
instantaneously? Answer, nothing.
