either. It is against our common sense. Although it was proved by some experiments, I still feel confused. The statement that A particle can be at different positions at the same time is still hard to imageine for me. If the statement change to that a particle has a mirror particle or a partner particle, then it is much easier for me to understand. Otherwise, if a particle can have two positions at the same time, why can't it have three or more positions at the same time? www.ddhw.com
