Is quantum mechanics on a measurement level a deterministic theory or a probability theory? If we know the quantum state of a (ideal) closed system, then we have the probability distribution of measurement outcomes for any of its observables. The state evolution is deterministic, measurement predictions are probabilistic. The probabilities here do not ...

Currently, we don't even know why the laws of quantum physics exist or what they are dependent upon, we only observe their properties, their results. The "random" decay of an atom is not without cause, it's machinations are simply unpredictable, too complex to predict accurately and therefore we call them "random" but then prove they are not random through ...
