WebA black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more … WebDifferent black holes have singularities containing different amounts of mass. The mass is not infinite. For example, if a star with a mass of 6 solar masses collapses to form a black hole, then the black hole is a 6-solar-mass black hole. The size of the event horizon is proportional to the mass.
