According to the interpretation, the interaction of an observer or apparatus that is external to the quantum system is the cause of wave function collapse, thus according to Paul Davies, "reality is in the observations, not in the electron".
根据这种诠释，观察者或外在于量子系统的装置是波函数坍塌的致因，正如保罗·戴维斯所说，“现实存在于观察之中，而不在电子之中”。
