the standard quantum theory. The Copenhagen interpretation of quantum mechanics stipulates that quantum states do not exist before or after they have “jumped" into an eigenstate associated with a real eigennumber, following the discontinuous wave function reduction triggered by a macroscopic measuring device.

In the following, we shall develop a proposal to reconcile classical physics, relativity and QM. To this end, we shall formulate a wave function reduction, which involves an absorber mechanism associated with the interaction of the measuring apparatus with the past and future light cones. The formalism provides an explanation for nonlocal quantum measurements and a resolution of the EPR paradox that does not violate special relativity, i.e. it does not introduce superluminal velocities. Our theory of quantum measurements is related to the transactional interpretation of QM proposed by Cramer[@Cramer1; @Cramer2], who describes quantum mechanical wave functions as real waves physically present in space. The transaction is a quantum event describing an exchange of advanced and retarded waves; it is explicitly nonlocal and consistent with Bell’s inequality, but is relativistically invariant and causal.

================================

In classical electromagnetism, certain solutions of Maxwell’s equations are discarded for empirical reasons. The field equations are time-symmetrical
