I am confused by the my readings on the subject. Does superposition says that the system has all the values at the same time or it has one of the possible values but we don't know which one until "measured". And is there different answers for different observables. Moreover, how do these systems know how to interact without carrying specific values. Also in the calculation the whole of the wavefunction is used, doesn't that tell us that all these values are real, ie. the electron does exist in all those positions as in the hydrogen, which means there is no such single electron in that case.
