Black holes and galaxies formations.

Black holes and galaxies formations.
-----
" . . . supermassive black holes with the mass of millions or billions of Suns are assumed
to reside in the cores of most galaxies, and they play a key role in current models
of how galaxies have formed over the past billions of years."
https://en.wikipedia.org/wiki/Introduct ... relativity
Correct.
Galaxies formations can have their source "black holes".
Why?
1- "A black hole of one solar mass (M☉) has a temperature of only 60 nanokelvins
(60 billionths of a kelvin) Hawking radiation"  / Wikipedia /
2- A black hole has a temperature within a few millionths of a degree
above absolute zero / Oxford. Dictionary./
3- "Stellar black holes are very cold: they have a temperature of nearly
absolute zero – which is zero Kelvin, or −273.15 degrees Celsius.
Supermassive black holes are even colder."
https://www.asc-csa.gc.ca/eng/astronomy ... k-hole.asp
My conclusion:
The cold and infinite cosmic vacuum has the same temperature as black holes.
It means that so-called "black holes" are only parts of the infinite cosmic vacuum.
So-called "black holes" are other names of the cosmic vacuum. And as was said
" . . . they play a key role in current models of how galaxies have formed over
the past billions of years."  as a process of quantum gravity going on for billions of years.

Afaik the temperature of space is about 2.7 Kelvin, supermassive black holes can be something like 15 orders of magnitude colder. So they don't evaporate much even if Hawking radiation is real. If the expansion of the universe continues indefinitely, the temperature of space will eventually drop even below that though, in the very distant future.

Afaik galaxy formation can happen without black holes too, those galaxies however don't have central bulges. Our second close big neighbour, the Triangulum galaxy seems to be such a galaxy, they never found a central black hole in it. Either there isn't one or it's tiny.

There are different sizes of "black holes": small,
big (at the center of our Milky Way lies a black hole whose mass is about 4 million times that of our sun),
super big ( black hole whose mass is billions of times more massive than our sun),
and even rotating black holes (was proposed by mathematician Roy Kerr).
"Many astronomers believe that black holes lie in the center of every galaxy"/Michio Kaku/
Every black hole emits radiation as a "form of black body radiation."/Hawking/.
The "blackbody radiation" is copy of vacuum radiation: "Kirchhoff vacuum" /by Max von Laue/
In my opinion, “black body radiation”, “vacuum radiation”, “black hole radiation”
is one form of radiation, caused by Dirac’s “virtual particles”.

zero Kelvin, or −273.15 degrees Celsius

According to " CIRCLE STUDY SYSTEM" , zero Kelvin, or −273.15 degrees Celsius is a " DIVING LINE" between our limited classic universe and unlimited parallel universe. And also , "ＣＥＲＴＡＩＮＴＹ＂　is our limited classic universe, while " UNCERTAINTY" is unlimited parallel universe.

I have to definitely agree with the texts on Socrattus' pictures:)

'Empty physical space = aether, has a regular 4-D structure . . .' /Cerveny/ . . . by Minkowski interpretation it is 4-D structure
"The views of space and time which I wish to lay before you have sprung from the soil of experimental physics,
and therein lies their strength. They are radical. Henceforth, space by itself, and time by itself, are doomed
to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.“
/ Hermann Minkowski /
What exactly is absolute Minkowski 4-D structure?

[Cerveny]

I'm afraid that Minkowski's space-time is complete nonsense. First, the Future doesn't exist yet. If it existed, the Universe would have to be determined and that to infinity! Secondly, time is not some preferred planar "wave", but it is simply the direction of the development of matter, locally perpendicular, radial to the Present, to the surface of the Past. Thirdly, nothing immediately, in principle, forces time to "run" everywhere at the same speed. If such a mechanism exists, it has, in my opinion, rather a corrective, elastic character...

And what about "famous quantum entanglement"? This would make from the "cone of the Future" a colander. I really don't know what's worse…

Hermann Minkowski said: "Henceforth, space by itself, and time by itself, are doomedto fade away
into mere shadows, and only a kind of union of the two will preserve an independent reality.“
Minkowski mathematical opinion has real indification - ID.
Only in the cosmic vacuum continuum are time and space inextricably fused together as
"only a kind of union of the two will preserve an independent reality.“

Minuscule black holes that formed right after the big bang could have had a strange property
called colour charge, and spotting them could help unravel the mystery of dark matter
