How much solar mass must a remnant have to become a black hole?

A black hole, in the theory of general relativity, can be composed of any mass. If the mass is low, the higher the matter's density has to be in order for a black hole to be created. There are no known processes that can produce black holes with mass less than a few times the mass of the sun. If black holes that small exist, they are most likely primordial black holes.

Without becoming a black hole, the maximum mass that a neutron star can possess is not fully understood. In 1939, it was estimated at 0.7 solar masses, called the TOV limit. In 1996, a different estimate put this upper mass in a range from 1.5 to 3 solar masses, until twenty years later, when it was determined that anything more than 2.16 solar masses becomes a black hole after a supernova occurs. Most neutron stars are between one and two solar masses, while most black holes discovered are determined as being four solar masses or above.

The maximum amount of the remnants should be 3 solar masses so that it can become a star. The moment that it goes beyond that, that is the time when there is a bigger possibility that the star will become a black hole. There are a lot of people who find black holes fascinating and scary at the same time.

They have the tendency to have strong gravitational pulls. They may pull the various objects that are within the path. The problem with this is they have the tendency to become bigger the more that they get more items within the same area. There are still some studies that are being done for this.
