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?
AFAIK there is no violation of PEP, let alone conservation of energy. The universe outside of the event horizon gains energy and the black hole loses it. Net gain/loss to the universe 0.When electrons or other fermions are sucked into a black hole, are they converted to energy? Otherwise, how is the PEP not violated then by the singularity?
