John Bell said there was no mystery in Albert Einstein's Hidden Variables. In the 1935 Einstein-Podolsky-Rosen Paradox, the four scientists posited that spooky action at a distance --nonlocal interaction of objects spatially separated-- could be explained by Hidden Variables. That is, two entangled particles could affect one another though light years apart, and this mutual influence was due to something hidden from observation. In 1981 John Bell said it could be explained by the socks on his friend's feet.
