Our official mythical / hypothetical astronomy.
=.
Let us think that black holes are real objects.
On the one hand.
1
Temperature of a black hole depends on the BH mass
T - h_bar c^3 / 8 π GM k_b
where h_bar is the reduced Planck constant, c is the speed of light,
k_b is the Boltzmann constant, G is the gravitational constant, and M
is the mass of the black hole.
2
a black body is also the best possible emitter of thermal radiation,
http://en.wikipedia.org/wiki/Black_body
3
The supermassive black hole at the centre of a massive galaxy or
galaxy cluster acts as a furnace, pumping heat into its surroundings.

The only major heat source is the supermassive black hole at the centre
of the galaxy or cluster – also known as the active galactic nucleus (AGN).

On the other hand.
‘. . . a black body is an idealized physical body that absorbs
all incident electromagnetic radiation. ‘
http://en.wikipedia.org/wiki/Black_body

Isn’t it a total a cosmological joke.
#
If you believe in black holes you aught to have your head examined.
What was seen was space contracting up to the event horizon
together with the end of time.
Some of us inherited the lie of omission and others have made
excuses for perpetrating it.
/ From an email /

On the third hand.
Astronomers have found an enormous hole in the Universe,
nearly a billion light-years across, empty of both normal matter
such as stars, galaxies, and gas, and the mysterious unseen "dark matter"
While earlier studies have shown holes, or voids, in the large-scale
structure of the Universe, this new discovery dwarfs them all.

On the fourth hand.
Cosmic cannibalising:
Images show one galaxy engulfing another

Looking at nice pictures that astronomers show us
be sure, they know to use photoshop.

Wait a minute. You lost me at "T - h_bar..."

 

[socratus]

On the one hand.
After the Big Bang all matter should have been annihilated
by its counterpart, antimatter. Luckily for us, Nature had
a preference for matter over antimatter.
/ Professor Nick Brook. University of Bristol /

On the other hand.
90% or more of the matter in the Universe / Vacuum is unseen.
Question :
Does one physicist’s hand know that the other hand do ?

Once again you prove that you don't know enough about the subject to have an opinion worth taking seriously. You can't equate black body radiation with a black hole's thermal emissions, they're not the same thing.

 

[darkbeaver]

Hawkings is the idiot conductor of the astrophysical asylum choir. A small stack of his books, glued together, is great replacement leg for my old couch. Sure I'm mad but not black hole mad,thankfully.
It's all electric, surrender now and you can keep all the black thermal emissions you can carry away.

 

[socratus]

You can't equate black body radiation with a black hole's thermal emissions,
they're not the same thing.

In 1859 Kirchhoff started to study interaction between heat
and radiation. In order to understand this effect he invented
the imaginary model ‘black body’
Max Laue called ‘ Kirchhoff black body’ as ‘ Kirchhoff vacuum’
The same definition ‘vacuum’ we can say about ‘black body’ .
Why?
Because the ‘black body’, the ‘ black hole’ , the vacuum can do
one and the same work: completely absorb radiant energy.
And therefore they are identical objects

[Dexter Sinister]

Well, at least you understand more than darkbeaver does. But how hard can that be?

 

[socratus]

What can be? What I can ‘understand more than dark beaver does.’

 

[Dexter Sinister]

Maybe you don't know that English idiom. It just means it's not hard to understand more than darkbeaver does, because darkbeaver's understanding of physics and cosmology is completely wrong.

 

[darkbeaver]

Sinister ,are you by chance a tenor ?

Everything falls into the black hole, he said, nothing can escape, he said, except x ray, they discovered, so which way does the matter and energy flow, they wonder. hawkings believes there are positive black holes which spew out and there are negative black holes that suck in and these are connected each to its opposite, on the other side, fullnes to emptines to fullness again for ever after, there we have the two stroke cycle engine of multiple universes, power and compression, there all Big Bang lunatics, drugs won't help

Universe ( beginning): which theory is right?
=.
On the one hand the Existence began from bing bang.

The Big Bang theory is the prevailing cosmological model of the
early development of the universe.

http://en.wikipedia.org/wiki/Big_Bang
=.

On the other hand the Existence began from Vacuum polarization.

In quantum field theory, and specifically quantum electrodynamics,
vacuum polarization describes a process in which a background
electromagnetic field produces virtual electron–positron pairs that
change the distribution of charges and currents that generated
the original electromagnetic field. It is also sometimes referred
to as the self energy of the gauge boson (photon).
Vacuum polarization was observed experimentally in 1997 using
the TRISTAN particle accelerator in Japan.

http://en.wikipedia.org/wiki/Vacuum_polarization

In the other words:
Theoreticians say that leaving our ‘atomistic- matter’
paradigm behind, and taking ‘virtual antiparticles’,
we realized that the background Cosmic Vacuum ‘polarized ‘
itself, and the result of this polarization we know as our world.
====.
Question.
What is the reason of ‘ the early development of the universe’ :
Big bang or background Vacuum polarization?

[damngrumpy]

Let me admit right off I know little about this subject. There is a question I have though
how can the universe be expanding if it goes on for infinity as some scientific projects
claim? Is it our galaxy expanding or is it the belief that the universe itself expanding. I
heard this on TV last week.

You know, it would be sufficient to really understand the electron.

Is it correct ?
Of course, it is correct.
Because only Physics can logically explain
the Existence, the Ultimate Nature of Reality.

But . . . but . . . as Einstein said:
“ One thing I have learned in a long life:
that all our science, measured against reality,
is primitive and childlike –
and yet it is the most precious thing we have.”

How to Unbalance Nothingness:
Physicists Calculate the Time Development of the Vacuum Decay


"The ground state of our world can't be described by the absence of all matter,"
Professor Dr. Holger Gies from the Institute of Theoretical Physics of the
Friedrich-Schiller-University Jena and the Helmholtz-Institute Jena explains.
"This so-called quantum vacuum rather turns out to be a complex
state of constantly fluctuating quantum fields with physical properties."

The world-wide community of physicists is hoping to be able to witness
a particularly spectacular characteristic in a few years' time:
the spontaneous decay of the vacuum into pairs of particles of matter
and antimatter in super strong electric fields.
Thanks to new research results of the Austro-German team of physicists,
this goal came a few steps closer.

Describe Quantum Fields out of Equilibrium

Although first theoretical consideration concerning the spontaneous
decay of the vacuum dates back to the year 1931, its comprehensive
understanding is still in its infancy.
"A great challenge in modern theoretical physics is the description
of quantum fields out of equilibrium," Professor Gies explains.
"We are facing this problem in phase transitions in the early Universe
as well as in many experiments in solid state physics."

Therefore experimental proof of the vacuum decay -- as it might be
delivered by high intensity lasers in the near future -- will provide
knowledge exceeding this particular field.
The scientists from Graz and Jena now succeeded calculating the time
evolution of the vacuum decay in detail.

"Even we were surprised by the results," Professor Gies confesses.
According to the results particles of matter and antimatter behave
in a novel self-focusing way and therefore the possibility of discovering
them is higher than expected.
"The quantum vacuum has already had some surprises in store,"
says the Heisenberg-Professor for Theoretical Physics.
"To unbalance this nothingness could develop into a new prolific
field of research."
The results of this co-operation have just been published in the journal
Physical Review Letters.

My questions and opinion.

What are physical parameters of Vacuum?
What are physical parameters of ‘so-called quantum vacuum’?

What is difference between vacuum and ‘so-called quantum vacuum’?

The reason that ‘quantum fields out of equilibrium,’ is polarization of vacuum.

What is mechanism of ‘ the self energy ‘ polarization?
Nobody tries to explain the mechanism of this process.
