If a star with 100 solar masses collapses in on itself does it create a neutron star or a black hole?

A black hole. There is a very specific condition that a star requires to implode and create a neutron star. To create a neutron star the imploding star needs to be just the right size no bigger than 1.5 solar masses and less the 5 times the mass of the our sun. Anything bigger than that creates the black hole phenomena. Which I theorize has an end point. Assuming that super massive black holes have the core mass of 1 billion solar masses there has to be an end point of hte solar masses it can reach before the phenomena itself beings the only thing that exists thus it can not suck in existing matter.

Ask me anything
