Actually, I fear that I misunderstood your claim. I thought you
pretended that, in the EPR experiment, two causal explanations were
possible without conflict with the principle of relativity ?

  * One causal explanation would pretend measurement A to be the
cause of measurement B without conflict with the relativity principle.

  * One causal explanation pretending measurement B to be the cause
of measurement A without conflict with the relativity principle.

However, when measurements A and B are space-like separated, any one
of these two causal explanations conflicts with the principle of
relativity of motion.

Moreover, the relativist time ordering cannot be assumed to define a
realistic (hence observer independent) cause-effect ordering because
the relativist time ordering between space-like separated measurements
A and B depends on the motion of the observer which decide to time
order them (with his relativist synchronization related time
ordering).

So where do these two incompatible causal explanations of EPR effect
stem from ?

So, what is exactly your claim ?

Compatibility of an interpretation of Alain Aspect experiment as an
action at a distance, in the framework of Aristotle space-time (with
an interpretation of relativist invariance as an intrinsic property of
physical phenomena that actually satisfy it rather than a geometrical
property of space-time that would exist independently of any
phenomenon occurring in it).
