I've just been reading my notes on quantum mechanics and got to the Pauli exclusion principle. The way it was explained makes no sense to me. It says "no two identical fermions can be in the same quantum state". Surely there are some restrictions to the applicability of this statement? It doesn't make sense to say that no two electrons in the entire universe can occupy the same quantum state. Any help would be much appreciated.
