We define: any two events which are indeterminate as to their time order may be called simultaneous.... Simultaneity means the exclusion of causal connection.... Yet we must not commit the mistake of attempting to derive from it the conclusion that this definition coordinates to any given event at a given different place. This would be the case only for a special form of causal structure, a form that does not conform to physical reality.
