Well you’ve just killed off a good portion of the quantum physics field.
What, because what quantum physicists hypothesize about things that cannot be directly observed?
The difference between quantum physicists and religionists is that if there are ever reproduce-able observations that contradict the current theories of physics, the physicists will modify those theories to account for the new observation. They may even throw out a theory in its entirety if new tools are developed to allow observations that were not possible prior to the invention of the tools.
Religionists just simply say that the observations don't exist.
