Is entanglement real or is it just that two things happen to be aligned the same way and measuring them reveals how they always were? Like if I gave two people

Is entanglement real or is it just that two things happen to be aligned the same way and measuring them reveals how they always were?
Like if I gave two people red balls without telling them what the colour is. One takes it out and sees it is red, the other now instantly has a red ball. But they were always red. So there is no actual interaction between the balls, they were just set up in a pre-defined matching state.
To our observations the balls are in a quantum state (the balls are wrapped in paper you can’t see through) but they always had a specific state. We just weren’t capable of determining that state because the interior is invisible to us. The interaction would always have produced that outcome, so it appears like they are communicating when in reality it would happen regardless.
- Jensson 3y agoWhat you are talking about is hidden variable theory, Bells theorem shows that it is likely not the case, so quantum entanglement is likely real. Bells theorem has been tested experimentally so we know the world works as it says, the question is just how we interpret it. https://en.wikipedia.org/wiki/Bell%27s_theorem https://en.wikipedia.org/wiki/Bell%27s_theorem
- aeonik 3y agoIt's interesting to read about the alternatives though. Like Global Hidden Variables. Also Superdeterminism might allow for Local Hidden Variables. https://en.wikipedia.org/wiki/Superdeterminism https://en.wikipedia.org/wiki/Superdeterminism https://en.wikipedia.org/wiki/Hidden-variable_theory https://en.wikipedia.org/wiki/Hidden-variable_theory
