I have been told on another forum I post to that there is a revolutionary theorem in physics which proves beyond doubt that the wavefunction (I presume meaning the one originally described by Schrodinger) is physically real. I have had various exchanges with the contributor who has told me this who is adamant that this is the case and equally adamant that I'm not sufficiently educated to understand it. I'm not a physics grad, but I have, I think, a reasonable layman's understanding of some of the issues sorrounding philosophy of physics. But doing a search on the theorem doesn't reveal much. It certainly doesn't seem to be a revolutionary idea, but who am I to say? So I just thought I would mention it here and see what other folks with some background in physics might have to say.
