A Principle Explanation of Bell State Entanglement: Conservation Per No Preferred Reference Frame

In this paper, we argue that the mystery of Bell state entanglement should be resolved via principle explanation rather than constructive explanation. Specifically, the principle responsible is "conservation per no preferred reference frame." Thus, the mystery of Bell state entanglement stems from one and the same principle responsible for the mysteries of length contraction and time dilation in special relativity, i.e., no preferred reference frame.
