If state reduction R occurs at critical points between one period of unitary evolution U1 and another U2, then the U1 might represent a false vacuum and the U2 a vacuum, with R representing the collapse of false vacuum. This is not the usual representation of state reduction.
Usually the state vector is contained in an abstract phase space related to condition of a quantum system. The present question is asking for opinions about a physical space time. Does the collapse of false vacuum map into a state reduction, or are the similarities occurring by chance?
Is Collapse Of False Vacuum A Physical Example Of State Reduction?
