Super-heavy black holes were already quickly created in the young universe.That was apparently a long time, and partly still, a mystery.
That surprises me personally again, because that is exactly what you would expect.To begin with, the primitive universe was still extremely dense, for a long time consisting of a kind of primemal plasma. Also at the time of the very first stars, the overall density was still very much greater than it is now. Seem to me the right ingredients for spontaneous collapsing of the hugely densely accumulated gas/matter, especially during the transition phase (and any phase changeover) from the Primegue plasma to the ‘ current ‘ matter state.
Also, in the extremely dense gas clouds, massive, close to each other, huge stars were born, which quickly consumed their fuel, thereby only a few million years old and massively ended their lives as a black hole.The remnants again formed new stars, but also new feeds for black holes. That again, melting with each other and being ‘ going out ‘ through the still very dense universe, were rapidly becoming heavier black holes.
Then the first galaxies were formed, still irregular, probably so critchy of the black holes in all sorts of shapes and sizes, already nourishing and mutually melting, moving towards the centers, eventually the SuperHeavy black To form holes in virtually every centre, with a large interaction between the structure and formation of the system and the mass of the superheavy black hole in the center.These young, still dense systems fused together again, with chewing super black holes circulating together, again mentioning, etc. With the result the extremely energetic and light-bright quasars that we now see in the mainly young universe.
And last, but certainly not least;-), the dark matter, more than a quarter of the total amount of matter, and hardly any inertia.This not yet with certainty to explain phenomenon (in the sense of ‘ from which ‘ existing, not ‘ or ‘), does have influence on gravity, but of course also, whether or not indirectly, is influenced by. The so-called maximum amount of matter that can take up a black hole is, in my opinion, extremely much larger than is often thought. It is much more greater and hassle-free by the accretion disc. I do not even know the name of the other ones who have the ‘ so-called ‘ limit of maximum amount of matter to be ordered by black holes once ‘ calculated ‘. 😉
Once through the observation horizon, there is no limit.Due to extreme relativity, everything disappears almost infinitely quickly towards singularity.
Another own idea is an acceleration of the process by using premature singularity formation outside the observation horizon, especially at quasars, due to the extremely high pressure of the incident matter in the inner part of the accretion disc.
All in all, it is in my opinion rather logical than enigmatic that in the early universe there were massive black holes.
We should not think in terms of compressed matter.We need to think in information.
Ask the question: How much information can a cubic cm contain empty space?A proton or neutron is such an information carrier. The more matter and thus information, is added to that cm3 space, the more gravity is generated. Until the space is overloaded with info, that it succumb or if in effect it has the creation of a singularity. A black hole is nothing more than space time that is overloaded with information.
