Copernican revolution in quantum mechanics

Abstract: The Ptolemaic system was adopted for a long time, because it made sense in its historical context. The reason for that was the belief that the Earth is stationary, just as it seems to be. In the same fashion, non-classical interpretations of quantum reality make sense in our time, because of the predominant assumption that classical wave interference is an illusion. The culprit is the appearance that waves go through each other unperturbed. In both cases, alternative models can be developed if the "obvious" nature of relevant phenomena is reconsidered.

Note: Our argument is based on the statement that modern scientists -- as a rule -- assume that interference is an illusion. It is not our claim that they always do so explicitly. If someone believes that a wave after overlap is "the same" as before the overlap, then it is logically implied that interference has no real effects. At the fundamental (i.e. quantum) level, one should imagine that input states remain unperturbed. This is the basis for the misconception that detectors necessarily reveal "path knowledge" for an isolated beam, even if it has interfered with another in its past. Without the identity assumption, it is very difficult (if not impossible) to prove that classical principles fail at the quantum level.
