Under what condition does the remnant of a supernova definitively become a black hole?
Answer
If the core left behind exceeds the maximum stable mass for a neutron star
If the red supergiant was exceptionally massive, the core remaining after the explosion will exceed the maximum stable mass limit for a neutron star, causing it to collapse indefinitely into a singularity.
