I don't understand what you mean by: "There's no event you can condition on that removes the correlations". To the contrary, it's not so easy to keep the correlations, i.e., the entanglement. Pretty little disturbances "from the environment" destroy the entanglement. It's hard to prevent decoherence, to the dismay of all taking up the challenge to construct multi-q-bit quantum computers.
I've no clue about Reichenbach's ideas. The little I've read from him rather lead to further strengthening of my prejudices against the value of "philosophy of physics" ;-)). The cause for the correlations described by entanglement is the preparation of a system in the entangled state. As the many very accurate Bell tests show, it's very well possible to prepare various kinds of entangled states like biphotons from parametric downconversion, and the preparation procedure is the cause for the entanglement and the observable stronger-than-classical correlations described by it.
Hm, I'm not sure, whether there's an ab-initio calculation leading to the chemical properties of nitroglycerine, but it may well be doable if needed (although it's tough; to accurately describe the phases of water it took decades!).DarMM said:Yes, but the point is that for many people the current account in QM is missing the "heated nitroglycerine explodes and the explosion collapses the wall " part.
This is even formally the case, where the QM correlations violate the Reichenbach principle of a common cause. There's no event you can condition on that removes the correlations, which is taken as typical of an "explanation" in statistics.
