# What would happen to pauli exclusion principle

Pauli exclusion principle say that no two electrons can occupy the same state. But what would happen if we force them to occupy the same states?

No two electrons can occupy the same state. Therefore your two cows *AHEM* electrons don't exist.

The pauli exclusion principle ultimately comes from the fact that the total wavefunction for a system of electrons must be antisymmetric. So, for example, if I have two electrons (with coordinates r1 and r2, respectively) and two states $\phi$ and $$\chi$$ the the total wavefunction would be
$$\Psi_{\rm tot}(r_1,r_2)=\frac{1}{\sqrt{2}}\left(\phi(r1)\chi(r2)-\chi(r1)\phi(r2)\right)\;.$$

so now, you tell me... what happens if the electrons are in the same state (i.e., if $\phi=\chi$)
