A supermassive black hole (SMBH) is the largest type of
black hole, on the order of hundreds of thousands to billions of
solar masses (M☉), and is found in the center of almost all
massive galaxies.
#
The origin of supermassive black holes remains an open
field of research.
Black holes created by a start or by a galaxy is science fiction. In order for a black hole to form the collapse would have to be symmetrical and because starts and galaxies rotate the greater portion of their mass is around their 'center-line' and that would make the 'top and bottom' as the weak spot during a time of collapse and as such that is where the compression would burst.

Didn't take much to make you clueless of is that your scientific answer? 2000F to 50F is how much energy released given the area in question. How about a smaller scale??

I didn't ask about ocean temperatures, comment upon them or bring them up at all in this thread ... anywhere ... ever.

You did mention our impact on the earth was 'more than a little', my post was showing that we are less than that and probably have zero effect in any meaningful way unless it is about us poisoning ourselves via altering natural food.

Why didn't you say that in the first place?



No. We can't change the planet, we can only make meaningless scratches on the surface that are very very temporary in the grand scheme of time.

...maybe ...

We still have a long way to go. The Earth's population has tripled in my lifetime and that is not very long. It will double again before it levels off. We are they modern equivalent of the Trilobite.

a) Thanks to science we know that the earth doesn’t
stay on three turtles.
Thanks to science we know that the heavens don’t
stay on the shoulders of the Atlas.
. . . . etc.

b) Thanks to modern science we know that existence began
from “big bang”.
Thanks to modern science we know that more than 90%
of masses in the universe are “dark matter” and “dark energy”.
Thanks to modern science we know that “supermassive black
holes” can “eat” all “big bang” matter.
Thanks to modern science we know that “string-particles”
exist in the 11-D or even in the 27- dimensions.
==.
My conclusion.
Even having high modern technology doesn’t prevent scientists
to create myths on the physical / mathematical basis.

Black holes are scientific fictions.
==..
In 1783 John Michell wrote that a big massive star would have
such a strong gravity field that light could not escape. Such objects
was called "black holes".

In 1928 Chandrasekhar realized that a star of more than about
one and a half times the mass of our Sun would collapse to a zero size.
In the other words Chandrasekhar mass-limit law says that stars mush
bigger than our Sun cannot exist in Nature ( it is impossible to create
snowball as big as the mountain Everest) Chandrasekhar's limit law
was awarded the Nobel Prize in 1983.
So, in my opinion, "black holes" are scientific fictions.
==..
a) But astronomers observed regions in the Universe without any light.
For example: unseen object called Cygnus X and a number of other
objects in our galaxy. Using entropy , quantum fluctuation ,
uncertainty principle astrophysicists say that the temperature of these
regions are only one ten-millionth of a degree above absolute zero.
The difference is so slight that I can say these regions have the absolute
zero temperature: T=0K.
( P.S.
Without entropy , quantum fluctuation . . . etc. their temperature is T=0K).

b) The detected material mass of the matter in the Universe
is so small (the average density of all substance in the
Universe is approximately p=10^-30 g/sm^3) that it
cannot ‘close’ the Universe into a sphere and therefore
the Universe as a whole is ‘open’, endless, infinite.

c) Only in local, limited regions this T=0K is broken.
In these limited, local regions the Newton’s and Einstein’s
Gravity limited laws are worked.

d) Book.
“There has also been mounting evidence that so-called
“supermassive black holes” lurk in the cores of most galaxies,
including our own Milky Way. Today, many physicists suspect
that giant black holes may be among the most ancient and important
objects in the universe, likely guiding the evolution of the galaxies
that now harbor them”.
/ Book: “Universe on a T-shirt” , page 113, by Dan Falk./

My commentary.

1) Chandrasekhar mass-limit law forbid existence of stars much
bigger than our Sun and therefore the source of so-called
“supermassive black holes” must be another.

2) As infinite cosmic continuum the Universe has the absolute
zero temperature: T=0K and it is core / harbor / source of all galaxies.

3) The evolution of all galaxies was begun from T=0K by the scheme:
a) first chemical element Helium II ( T=2,17K)
b) second chemical element Helium I ( T=4,2K)
Every scientific amateur knows about strange behavior of He-II and He-I.

How Do Black Holes Form?
Primordial black holes are thought to have formed
in the early universe, soon after the big bang.
Stellar black holes form when the center of a very
massive star collapses in upon itself.
This collapse also causes a supernova, or
an exploding star, that blasts part of the star into space.

https://www.nasa.gov/audience/forstudents/5-8/features/nasa-knows/what-is-a-black-hole-58.html

Soon after the big bang a very Primordial massive star collapses in upon itself . . .
#
By absorbing other stars and merging with other black holes,
supermassive black holes of millions of solar masses (M☉) may form.

https://en.wikipedia.org/wiki/Black_hole

Questions:
1 - In which Reference Frame the very Primordial massive
Star collapsed, soon after the big-bang ?
2 - What was temperature of the RF where the very
Primordial massive Star was collapsed ?

How Big Are Black Holes?
#
'' The largest black holes are called "supermassive."
These black holes have masses greater than 1 million suns
. . .
The supermassive black hole at the center of the
Milky Way galaxy is called Sagittarius A.
It has a mass equal to about 4 million suns . . .''

From Primordial - "Micro black hole"
/ would have a mass >~ 10^-5 gram /
to Supermassive about 4 million suns . . . after big-bang . . .

What If Einstein Overlooked Something?
/ Don Lincoln , Contributor /
---
'' . . . in order for gravity to act in the way in which it is observed,
which is to weaken between two objects as one over the square
of the distance separating them, the graviton has to have a handful
of properties. It must be massless, and it must travel at the speed of light. ''

Dark matter nightmare: What if we are just using the wrong equations?
---
Einstein’s theory of general relativity is an extremely well-confirmed theory.
Countless experiments have shown that its predictions for our solar system
agree with observation to utmost accuracy.
But when we point our telescopes at larger distances, something
is amiss. Galaxies rotate faster than expected.
Galaxies in clusters move faster than they should.
The expansion of the universe is speeding up.

General relativity does not tell us what is going on.

Black holes stunt growth of dwarf galaxies
Astronomers find large-scale winds associated with active
black holes in small galaxies suppress star formation
Date: October 11, 2019
Source: University of California - Riverside
Summary:
Astronomers have discovered that powerful winds driven
by supermassive black holes in the centers of dwarf
galaxies have a significant impact on the evolution
of these galaxies by suppressing star formation.

Micro-black-hole
''In principle, a black hole can have any mass equal to or above
about 2.2×10−8 kg or 22 micrograms (the Planck mass)''
https://en.wikipedia.org/wiki/Micro_black_hole
. . . so, it is no problem to know the local event horizon
of micro_black_hole and because '''' Black hole swallowing
and ripping apart star . . . ''
https://news.sky.com/story/black-ho...g-apart-star-captured-for-first-time-11820432
. . . it can have possibility to grow and become Supermassive
black hole . . . '' The minimal supermassive black hole is
approximately a hundred thousand solar masses'' . . . and
'' So-called ultramassive black holes (UMBHs), which are
at least ten times the size of most supermassive black holes,
at 10 billion solar masses or more, appear to have a
theoretical upper limit of around 50 billion solar masses ''
https://en.wikipedia.org/wiki/Supermassive_black_hole
Of course this process (since the Big Bang) took long time:
''The current measurement of the age of the universe is
13.787±0.020 billion (109) years within the Lambda-CDM
concordance model.''

Holographic Duality Yields Breakthrough in Black Hole Physics
By Skolkovo Institute of Science and Technology (Skoltech) November 5, 2019
---
The physics of black holes remains an elusive chapter of modern physics.
It is the sharpest point of tension between quantum mechanics
and the theory of general relativity.
According to quantum mechanics, black holes should behave like other
ordinary quantum systems.
Yet, there are many ways in which this is problematic from the point of view
of Einstein’s theory of general relativity.
Therefore, the question of understanding black holes quantum mechanically remains
a constant source of physical paradoxes. The careful resolution of such paradoxes
should provide us a clue as to how quantum gravity works.
That is why the physics of black holes is the subject of active research in theoretical physics.
