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.

amazing universe , black holes and galaxies, of course, amazing post also.

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.

7 dimensions:
The 7th dimension is an infinite space-time universe with infinite dark matter and dark energy, which corresponds to the limited dark matter and dark energy in our 6-dimensional classical finite space-time universe. If the 7th dimension is an infinite icy ocean, then our 6-dimensional classical universe is just This is just a small and limited small hockey puck!


Parallel universe︰
If 7 dimensions are infinite dark matter and dark energy, then infinite parallel universes are the "infinite variables" produced by the mutual transformation between 7 dimensions of infinite dark matter and dark energy! The parallel universe is also the "infinite consciousness cognitive fantasy world" in our human consciousness and even subconsciousness!

The meaning of this "infinite variable" is both profound and broad. That is, the tens of billions of differences, big or small, between everything in our universe and in the world are just "outside" of the parallel universe, that is, the parallel universe. 's "masterpiece".

This classical universe and the infinite parallel universe are interdependent like Yin and Yang, and like Heisenberg's certainty and uncertainty in quantum mechanics. We all know that everything has both certainty and uncertainty. Our destiny So is it! Since this classical universe is in the Great Expansion stage, "dark matter is converted into dark energy" (the Big Collapse is when dark energy is "crystallized" into dark matter. In fact, if we go into detail, these two stages are interlocked and "inseparable from each other". ), so certainty generally occupies the "dominance", while uncertainty is hidden within. This is just like the Tai Chi fish picture, certainty is the "fish body" of the white fish, and uncertainty is its "black eye" ,vice versa. The classical universe we are talking about cannot be separated from the parallel universe, otherwise it will be meaningless, just like the interlocking beads in the theory of Buddhist beads in the Circle Theory, which coexist and prosper together.
Of course, it can also be said in a layman's terms that this universe is theoretical, while parallel universes are ever-changing in practice; this classic universe is "dead", while infinite parallel universes are "living".

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”.

Certainty -- substance -- classic universe -- over -273.15 degrees Celsius -- Thermal fluctuations

Uncertainty -- energy -- parallel universe -- -273.15 degrees Celsius -- quantum fluctuations

A good conclusion , it almost going to a point that -- black hole is more like dark matter, cosmic vacuum is more like dark energy .
Of course, dark matter and dark energy can convert into each other , they are mutual roots, and so black holes and cosmic vacuum are likewise.

if sth equal to or lower than -273.15 degrees Celsius is surely without thermal fluctuations, those stuffs are only with quantum fluctuations, quantum fluctuations is sth " NOT EVEN ALIVE OR EXIST"　ｉｎ　ｏｕｒ　ｃｌａｓｓｉｃ　ｕｎｉｖｅｒｓｅ，　they are only "EXIST" IN 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.“
