But what does 'the present state' mean? The present second? The
present milli-second? "Present" is not a relativistic concept.
Your pedantry is misplaced. The present state and the present moment
are both sufficiently well-defined for quantum system essentially at
rest relative to you in your laboratory. The view of some remote
observer with relative velocity approaching that of light is not a
relevant consideration.
It is relevant to which parts of a non-local state are in the
"present" when we measure the state.
Muddying the waters by irrelevant references to EPR and non-locality
again, Brent? We are talking about superposition, not entanglement.......
