Sometimes, accepting the Copenhagen Interpretation is understood... to use the quantum recipe without... question: Shut up and calculate. Such reject… - Tim Maudlin

A physical theory should clearly and forthrightly address two... questions: what there is, and what it does. The answer to the first... the ontology... to the second... its dynamics. The ontology should have a sharp mathematical description, and the dynamics... implemented by precise equations describing how the ontology... evolve[s]. ...All three of the theories we will examine meet these demands.

Non-locality appears at exactly the point where the "measurement problem" which infects standard quantum theory is resolved.

[S]pace and time... do not appear to our senses: they have no color or flavor or sound or smell or tangible shape. ...[They] seem rather to have is a geometrical structure.
