primordial black hole comparison table

Subject is a kind of has definition

black hole massive compact halo object A gravitationally collapsed mass inside the Schwarzschild radius (q.v.), from which no light, matter, or signal of any kind can escape. A black hole occurs when the escape velocity of a body becomes the velocity of light (2GM / R = c²). If an object with the mass of the Sun had a radius of 2.5 km, it would be a black hole. Black holes represent one of the possible endpoints of stellar evolution for stars very much more massive than the Chandrasekhar limit.

primordial black hole black hole Small black hole hypothesized to have formed during the first 10^-43 seconds of the universe, when quantum effects were very large.
