Lawrence,
You suggest; "it is very clear the loop holes for there being a classical underpinning to quantum physics are closed." So most believe, but John Bell, who closed them for certain assumptions DID NOT! so most misunderstand his 'theorem'. If you study the solution you'll see for yourself, but for rigour let me quote Bell;
"The founding fathers of quantum theory decided even that no concepts could possibly be found which could emit direct description of the quantum world. So the theory which they established aimed only to describe systematically the response of the apparatus... ...in my opinion the founding fathers were in fact wrong on this point. The quantum phenomena do not exclude a uniform description of micro and macro worlds...systems and apparatus." 'Speakable'...p.170-171. also p 172 & 173;
"a real synthesis of quantum and relativity theories requires not just technical developments but radical conceptual renewal.
"..conventional formulations of quantum theory, and of quantum field theory in particular, are unprofessionally vague and ambiguous. Professional theoretical physicists ought to be able to do better." ."
Ch.3. In stating his belief that his theorem must be effectively circumvented with some new approach; "...the new way of seeing things will involve an imaginative leap that will astonish us. In any case it seems that the quantum mechanical description will be superseded." p.27. And Ch 20 p.194;
"...the 'Problem of Interpretation of QM' has been encircled. And the solution, invisible from the front, may be seen from the back.."
Experiments have NOT changed that, only confirmed his theorem using the same QM assumptions he 'freely used' for it. Indeed he actually suggested the 'round the back' solution we use (p.175) as "fermion number density."
So we shouldn't just accept the beliefs about QM banded around. John Bell knew better and I think we show he was correct. Take a look. It may inspire you!
Very best.
