Sometimes, in the universe, two particles (theoretically, any two things) become entangled with each other and act in unison even when there is no force between the space that separates them. It violates Einstein’s theory of causality because it would mean that there is something deeper that unites them that transcends the laws of space, that challenges our present understanding of the universe.
It was first described in the EPR papers of Einstein and is sometimes called the Einstein-Podolsky-Rosen paradox. However, if you try to harness this for the larger faster-than-light communication, quantum mechanics makes it impossible to obtain the same result. Thus, accounting for statistics, the violation is considered gone.
Einstein dismissed it as the “spooky action at a distance”.
Love is Einstein-Podolsky-Rosen paradox.
God is that spooky action at a distance.
