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."
Introduction to general relativity - Wikipedia
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."
Fact sheet: Black hole
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.

Pretty big difference between 0.00000006 K and 2.7 K, the temperature of the “cosmic vacuum”.

The_Metatron wrote:Pretty big difference between 0.00000006 K and 2.7 K, the temperature of the “cosmic vacuum”.

The cosmic microwave background (CMB) is the result of later fluctuations of Dirac's quantum "virtual particles" in the "vacuum sea".

Prove it.
