What force causes extremly high mass stars to turn into black holes instead of nuetron stars?

Answer:
Black holes are formed by super massive stars when they collapse. Less massive stars will form neutron stars. Therefore, the original size and mass of the star will determine if a black hole will be created when the star collapses.
