So, you got n,l,m_l,m_s. If you have two hydrogen atoms on opposite ends of the universe, it seems to me that the electron in each could have the set of quantum numbers (1,0,0,1/2).
Now, if you have a helium atom, because its two electrons are identical fermions, by the PEP they now "know" about each other, and can't have the same set of quantum numbers... So how close do two electrons have to get before this happens?
