Kirchhoff & Planck = Michell & Hawking.
===============================
The question is:
Hawking radiation theorizes that black holes do not, in fact,
absorb all radiation absolutely; they give off some return radiation.
How does this radiation escape?
========================
1.
G. Kirchhoff in 1859 thought up - an absolutely black body.
( Kircchoff 's vacuum radiation / Max Laue/ ).
Absolutely black body is imagined body absorbing all
falling radiation on it. Quantum of light which will get this area
practically will not radiate back.
2.
The concept of a black hole, so massive, that even quantum of light can not
to escape from it, was put forward by John Michell in 1783.
3.
It is visible that the Kirchhoff 's model (absolutely black body) and
the Michell's model (black hole) are identical.
4.
Quantum of light which got into area of
“absolutely black body ” and practically
did not radiate back.
But it is known, that such condition means" thermal death ".
And in Nature it is not observed.
Therefore Max Planck, studying this area, came to a conclusion:
Such condition can change when radiation of quantum of light
having own internal impulse h=Et will take place.
5.
In 1974 S. Hawking came up with theoretical arguments
showing that black holes are not really entirely black:
they can emit radiation.
6.
Now all of us will wait for " new Max Planck ",
who will prove, that
" famous Hawking's radiation " / A. Sakharov / consists of
quantums of light, which are describe with the formula h=Et.
7.
We have again invented a wheel,
we have again discovered America.
========================
It is interesting for me to know, where the man keeps his brain,
if he does not see, that " absolutely black body " and
" black hole " are identical models?
-
That strange quantum theory has a provision that makes possible the activity of particles "tunnelling out" from the blackhole--Hawking's radiation.

But before we must understand : to which
reference frame does the “ black hole” belong?
-
Other question:
The Quantum physics approves, that the " virtual particles "
are connected with Vacuum.
To which reference frame does the “'dark matter'” concern?
-
1.
An absolutely black body is a hypothetical body that
completely absorbs all the radiation falling on it.
Physicists said: “No such body can exist.“
2.
Black hole, is a region of space which no radiation
can be run away from it.
3.
The Absolute Zero: T=0K is a region of space
in which the motion of radiation died.
4.
But Planck said that from absolutely black body
a quantum of light can radiate.
5.
But Hawking showed that black holes can emit radiation.
6.
And the quantum theory said that in Vacuum there is
“ virtual motion of particles. “
7.
Maybe absolutely black body and black holes are
Only models of region of Absolute Zero space: T=0K.

Hi, socratus.
I have thought these scientist area few years. My basic is electrician but i'm interesting also space-nature scientist problems.
My thought is that this Kelvin-basic radiation temperature-scale is wrong method to explore space age or planet temperature basic elements. Also i think that when scient has lock (earlier 19-century) this Kelvin-theory and also constant c together comes bigger mixing problem and our measuring technics and theoryes need new theoryes.
What i think.
Space dont has any kind of black hole or etc. Also distances what we measure is wrong theory-basic because of constant-value c. I think that example. sun send colors-particles (of cource we can say light-particles also,) anypath, sun or other light-source(lamp, etc.) send "light-color-particles-stuff"=matter particles. I think that these matter-particles are much smaller size than we believe through our atom-theory basic. And i also think that these particles has many differant speed or speed(y)/distance(x) travell going curve. Therefore i think that many object at space is much near than we think and many object is much far than we think.
Also we must remember our research-time. If we have study space few hundred years, using satellite only 20-30 years. This is so short period that we cannot basically says anything absolute thruth how planets or planets systems born, grown, or what is these systems motion direction or speed.
But this radiation is quite complex thing.
What is radio-wave? Without matter cannot happend any kind of matter-vibration, like radio-wave motion. Still radio-waves goes through space, so that means that space is full some kind of matter-stuff, which is smaller size than our atom-theory can explain.
But like atoms, is quite difficult to see, so it's smaller size matter particles, and i dont that is is not necessary.
Radiowave goes through paper or wood or window. Light source matter-particles dont goes through paper like colors or light, but colors and light goes through window. Hmm. This color-image-flow (what we see and come to our eyes) is quite interesting area.
I think that next question is quite important to solve, then we maybe understand little bit more how nature works. (Life-existing is still mysterious.)
How image from some object can flow to my eyes through air-matter or window but not thin paper or woodplate?
