Or to put it another way, if you start with a unphysical premise then you will reach a unphysical conclusion and that does neither mathematicians nor physicists any good. > > > You can define the universe by some solution of some equation > Yes, and I can define 7 as 2+2+2 provided that 2+2=5; garbage in garbage out, if you start with a unphysical premise (like a viewpoint that can not exist) then you will reach a unphysical conclusion (like things can be deterministic local and realistic) regardless of how scrupulously you've manipulated the mathematical symbols. And you seem to have a unhealthy reverence for definition and a belief that if human beings can define something then that magically confers a physical reality to it. I can define Harry Potter as a bespectacled boy wizard but I have never physically met him nor do I expect to.
