Science: When a white dwarf star goes over the Chandrasekhar limit, its electron degeneracy pressure fails. The electrons combine with protons (inverse beta decay) to form neutrons, and the star collapses to form a neutron star. When a neutron star goes over the Tolman–Oppenheimer–Volkoff limit, neutron degeneracy pressure fails, and it collapses to form a black hole.

Now the neutrons have to turn into something else on the way down. What? Strange matter? Free quarks? Di-baryons? Something we haven't thought of yet? Nobody knows. But we're working on it, with gamma-ray spectroscopy, LIGO and other gravity wave telescopes, the IceCube Neutrino Observatory neutrino detector at the Amundsen–Scott South Pole Station, and lots of big particle accelerators.
