Consider a collapsing star. If it is more than 1.3 solar masses, it becomes a neutron star, shrinking stopped by Pauli principle (neutrons are Fermions). If it is somewhat larger it becomes a black hole (blackhole radius is proportional to mass, geometric radius for constant density is proportional to the cube root of mass). According to gen. rel., the black hole should collapse into a singularity. What happened to the Pauli principle? What happens to the neutrons (or constituent quarks) on a microscopic scale? Is it some exotic form of matter, yet unknown?
