I think you will enjoy reading my article about how Relativity and Quantum Mechanics could be both talking about the same underlying reality: How all the massless carriers we picture as wandering the universe at the speed of light represent, at the same time, the instantaneous entanglement between an emission event and a detection event that appear separated in spacetime only to material observers, but not to the massless carriers themselves.

Starting from this notion of entanglement (that comes from Special Relativity), we can solve all riddles on Quantum Mechanics.
