that correct quantum mechanical wave equations should be first order with respect to the time variable, so as to uniquely determine the state and the time evolution of the system. Moreover, the concept of retarded and advanced waves is generically a classical notion. Feynman’s propagator $D_F$ in quantum electrodynamics is completely symmetric under time reversal, so that if we interchange the emitter and absorber labels of a photon under time reversal, then the resulting physical situation occurs with equal probability compared to the old one. However, in classical physics radiation phenomena involve large numbers of photons traveling in different directions in a correlated manner, so that the absence of converging waves can be attributed to the absence of correlation between different parts of the universe.

By making the transmission of “nonlocal" information with only photons, we avoid the problem of quantum wave transmission by advanced wave solutions associated with massive particles. Our transmission of information for nonlocal measurements is purely an electromagnetic wave phenomenon associated with the quantum measurement device and the collapse of the wave function.

Absorber Mechanism and Cosmology
================================

The criterion for the existence of a complete absorber is based on arguments of the attenuation of the
