the wave function.

We shall make the following postulates:

1.  Before and after a measurement by a macroscopic apparatus, with a corresponding reduction of the wave function, the electromagnetic field is described by the retarded solution given by Eq.(\[retarded\]).

2.  For purely [*local*]{} measurements of the particle the electromagnetic field is given by the retarded solution, Eq.(\[retarded\]), and there is no effect felt by the particle at $O$ from an absorber stimulus either in the future or in the past light cone. Thus, for local measurements of a particle and its properties, the measuring apparatus [*does not interact with the absorber mechanism in the past and future light cones*]{}.

3.  During a [*nonlocal*]{} measurement in the short time interval $t_1 < t < t_2$, the wave function reduction is correlated with an interaction of the particle being measured, situated at the apex $O$ of the light cone, with the absorber mechanism in the past or future light cones. This has the effect of time reversing the field at the particle into the solution given by Eq.(\[advanced\]).

We must now guarantee that transmission of information takes place between the two entangled systems $A$ and $B$ which are spacelike separated, without invoking
