This question already has an answer here:
From my understanding of entanglement, and what it tells us about reality, the state the quantum system is in would have to be decided before measurement. This would mean that everything about our reality has been determined beforehand. The measurements are correlated regardless of what axis we choose because that choice is not actually a choice but a known part of a greater "plan".
If the quantum state collapsing to accommodate the results we measure and the measurement itself were truly simultaneous, that would essentially mean that the results are dependent on the measurement and the measurement is dependent on the result. Since something cannot be the result of an event that hasn't happened yet, where does that leave us?
How can a measurement cause an event and then return results that are predicated on the aftermath of that event? Since the pre-measurement state of a system and the post-measurement state of the system are temporaly distinguished, it seems like giving into the idea of super-determinism is the most logical conclusion here.
