The Bell Test rules out the possibility of a local hidden variable theory explaining quantum entanglement. That means the states of the two entangled particles are not simply unknown before measurement, they do not have independent states.
This means either, when you measure one particle it “instantaneously” affects the other, which has weird implications for causality because which particle is measured “first” can depend on your reference frame.
Or there is something statistical and truly random going on.
Oh I didn’t mean to refer to hidden variables. I think there’s just a fatal superfluence of available variables. Rather than an inability to know, the problem is an inability to know everything all at once.
What’s the good reason?

The Bell Test is still a cool proof though.
