RE: Black Holes.

in #science8 years ago

What you are describing is simply a hypergiant. They will start nuclear fusion, but collapse very quickly, within a few million years. But even such conditions are very, very rare. To directly form a black hole, the density would have to be greater than anything observed in the universe today. There may be a couple of such corner cases, but thus far, all supermassive black holes discovered were formed from stellar collapse and subsequent mergers.

However, moments after the big bang, this may have happened though - the density was trillions of times higher. Enough to create what are called primordial black holes.

Sort:  

Big bang? The big bang is mathematically impossible... also big bang universes cannot exist in black hole universes... black holes can't exist in black hole universes. The theory of star creation as coalescing from gravity is completely flawed... ha ha.. yes. bones quotes wikipedia... heaven help us.

No, I am describing a "quasi-star." https://en.wikipedia.org/wiki/Quasi-star Science actually doesn't know for sure what the progenitors of supermassive black holes were. There are several hypotheses at this time.

Quasi-stars and primordial black holes seem to be the same thing. You'll see the important point for both are "very early in the Universe's history".
