What mass limit must the residual core of a dying massive star exceed to form a black hole?
Answer
About 3 solar masses
If the remnant core mass after a supernova explosion surpasses approximately 3 solar masses, neutron degeneracy pressure cannot halt the collapse, resulting in the formation of a black hole.
