Is the Moon There When we are not Looking?

"Strictly speaking what we proved is that the question of context in the macroscopic world is an ill-posed one because of the limited class of feasible measurements one can perform. The smaller set of measurements leads to a simplification of quantum theory that removes certain non-intuitive features such as contextuality while still preserving other features such as entanglement [10, 11]. Similar phenomena were observed in a toy model of quantum theory proposed in [12]. An interesting open question is to investigate the complexity of measurements needed for contextuality to emerge." arXiv
