A real solution to the quantum mystery The quantum mystery is a metaphysical problem not mathematical or logical because it concerns the starting-point for our world, decisively including the starting-point for all knowledge. The reason we struggle to understand this mystery is because we fail to grasp this metaphysical implication. We fail to appreciate that the discovery of quantum interaction has brought into question the way we initially apply the law of noncontradiction as a fundamental ontological law and as the first law of logic in our world. This discovery, at the very limit of the observable world, has exposed the error in our traditional application of this truism as an a priori law. It's the way this law applies, not merely its status as a logical truism, that defines its meaning as a fundamental law in our world. The solution to the quantum mystery, the real starting-point for our world, and how this fundamental law initially applies in our world all amount to the same problem. Once we come to terms with this realisation, the answer to the quantum mystery becomes surprisingly simple.
