Once again, here is a link to an article discussing
the Aspect experiments.

Perhaps WM would care to explain "physically instantiated" in
respect to the conclusion of that paper:

"Most particles or aggregates of particles that
are ordinarily regarded as separate objects have
interacted at some time in the past with other
objects. The violation of separability seems to
imply that in some sense all these objects
constitute an indivisible whole. Perhaps in such
a world the concept of an independent existing
reality can retain some meaning, but it will be
an altered meaning and one remote from everyday
