The starting point of this idea is the example:
That belief crumbled when experiments began to reveal the indeterministic effects of quantum mechanics—for instance, in the radioactive decay of atoms. The problem goes like this, Tollaksen says: Take two radioactive atoms, so identical that “even God couldn’t see the difference between them.”...
Obviously this example miss the state of each atom. There is no way that two atoms at exact same state at any given moment. Therefore, they are not "identical" to have exact same behavior.
The second question is about the experiment:
... First the physicists would measure spin in a set of particles at 2 p.m. and again at 2:30 p.m. Then on another day they would repeat the two tests, but also measure a subset of the particles a third time, at 3 p.m. If the predictions of backward causality were correct, then for this last subset, the spin measurement conducted at 2:30 p.m. (the intermediate time) would be dramatically amplified. In other words, the spin measurements carried out at 2 p.m. and those carried out at 3 p.m. together would appear to cause an unexpected increase in the intensity of spins measured in between, at 2:30 p.m. The predictions seemed absurd, as ridiculous as claiming that you could measure the position of a dolphin off the Atlantic coast at 2 p.m. and again at 3 p.m., but that if you checked on its position at 2:30 p.m., you would find it in the middle of the Mediterranean.
What is the true cause of the difference of 2:30 result? If the 3:00 measurement impacts the 2:30 result, then whatif we can simply stop the 3:00 measurement when we see the larger change in the 2:30 measurement? Can 2:30 result reverse? Obviously no. So logically, 3:00 measurement should not the cause of the 2:30 result. Then if the decision of the 3:00 measurements becomes the cause of 2:30 result, we can simply not make an decision until we have the 2:30 result or make decision than cancel the measurement later. I would like to see that experiment result.
Very questionable idea and experiment.
