Thanks for your post.
From all of the literature that I have read over the past 15 years, I've never seen an explanation of the wave function as something real. Bohr and Born define the wave function as a "probability wave." I think that what you suggest has already been proven to be not real: the existence of an ether within which waves can propagate.
In one of Einstein's 1905 papers, he physically demonstrated that photons are physical quantum particles. Electromagnetic waves propagating through space are made up of an ensemble of many many quantum particles interacting with each other to behave as larger waves. There's no connection here to the quantum mechanics' "wave function," I don't think.
I ask a favor from you: Could you please vote for my paper? I really want to try to get the attention of the quantum mechanics physics community if at all possible.
