你还是把这个事想的太简单了。惠勒延迟选择是一个影响很大，有广泛讨论的思想实验。如果能像王一以为的那样简单去解释，不会被反复讨论。惠勒和Zeilinger这些人，无论在物理方面还是在物理哲学方面，所想的显然都应该比王一之流更深。特别是物理哲学方面的思考，不会因十年几十年的时间就“过时”，千年也未必。
Zeilinger et al. have summarized what can be known as a result of experiments that have arisen from Wheeler's proposals. They say:
Our work demonstrates and confirms that whether the correlations between two entangled photons reveal welcher-weg information or an interference pattern of one (system) photon depends on the choice of measurement on the other (environment) photon, even when all of the events on the two sides that can be space-like separated are space-like separated. The fact that it is possible to decide whether a wave or particle feature manifests itself long after—and even space-like separated from—the measurement teaches us that we should not have any naive realistic picture for interpreting quantum phenomena. Any explanation of what goes on in a specific individual observation of one photon has to take into account the whole experimental apparatus of the complete quantum state consisting of both photons, and it can only make sense after all information concerning complementary variables has been recorded. Our results demonstrate that the viewpoint that the system photon behaves either definitely as a wave or definitely as a particle would require faster-than-light communication. Because this would be in strong tension with the special theory of relativity, we believe that such a viewpoint should be given up entirely.[24]
