But you don’t need a star to die to make a black hole. In 1971, Stephen Hawking, drawing on an idea earlier suggested in 1966 by the Russian physicists Yakov Borisovich Zel’dovich and Igor Dmitriyevich Novikov, theorized that intense pressures during the Big Bang could have collapsed matter directly into black holes. Those primordial black holes could be of any size and could be anywhere. A black hole as massive as Earth would be about the size of a Ping-Pong ball and would be exceptionally hard to see.https://www.nytimes.com/2020/09/11/science/astronomy-planet-nine-black-hole.html
I wonder how this ties in with the Universe work?
