Good evening. I have been reading that the repulsion generated by the Pauli exclusion principle barely prevents neutrons in neutron stars from occupying the same quantum states (after all, they are fermions). However, the principle seems to be violated in a black hole, given that fermions are compressed to the point where everything is in the same place (the singularity). For example, what happens to a proton as it approaches the singularity? I am wondering if the exclusion principle is violated in black holes. The alternative would be that at some point, matter gets turned back into energy (given that matter and energy are equivalent, it seems plausible); the Pauli exclusion principle would no longer apply because the fermions would have turned into energy, thus the principle would not be violated. What are your thoughts on this? Thank you in advance.
