So as far as I am aware, there is currently no cause that explains how exactly two entangled particles remain correlated even when separated at a large distance. If there is a cause, it is presumed to be non local.
My question is: apart from this, is there any other example in physics (perhaps classical physics) where correlations between items separated at a large distance occur without either a common cause or a cause that involves communication between these objects?
Notice that I use the term common cause. This is because I can imagine a classical scenario where if I had two boxes, one containing a blue glove and one containing a green one, and I sent them out into different corners of space, and I opened one box and it had the green glove, I would immediately know that the other box contains a blue glove. Even though there is no communication, this is not an analogy to entanglement, since each box contains a definite state of being that glove, and the cause for this is the fact that at the origin point, I had boxes containing two gloves. Thus, this correlation still occurs because of a cause.
Is there any example in classical physics or really anywhere else where a consistent correlation between objects does occur without any cause?
