primordial black hole

(PBH)
(black holes forming at the most dense volumes when inflation ceased)

The term primordial black hole refers to theoretical black holes formed in the very early universe, that did not form from the collapse of stars. There are a number of theories of how some might have formed:

Theories vary regarding their resulting mass distribution. Some theories suggest some could be large and could be seeds or contributors to the early supermassive black holes (SMBHs) known as quasars. Other theories suggest black holes smaller than stellar-mass black holes, with masses down to the minimum for a black hole and up into the mass range of asteroids. It is presumed that the small ones might have evaporated due to Hawking radiation, but the rest still exist. Such small ones are sometimes termed miniature black holes or micro black holes.
