In entanglement, two electrons have the same spins measured at the same time. But how is same time defined, in light of special relativity's time dilation? Doesn't this mean that, from another frame of reference, they will not be simultaneous. That means, that person in point A, knows in advance, what will be the spin in the future point B. Isn't this prediction of the future? In which reference frame is the measurement simultaneous?
