Some models in physics./ My opinion./
We drink the water - something physical/ material.
We don’t drink mathematical / chemical formula H2O.
In our physical body the material blood flows.
Not the formulas of blood flow in our body.
In the Universe there are many elementary particles.
Not models of ‘ particles - points’ exist in the Universe.
Models and formulas must describe the real picture of Nature.
I think that it is impossible to take abstract model as fundament
of reality. Why? Because reality comes from reality and
reality creates reality. And if we reach a point where we
need to bridge between abstract and reality, and that's the point
where the axioms, hypotheses, and postulates are needed.
And they lead us to paradoxes and puzzles.
If our primary model is abstract then all physical construction
is created on the sand.
G. Kirchhoff in 1859 thought up - an absolutely black body.
Absolutely black body is imagined body absorbing all
falling radiation on it. If quantum of light will get into
this area it will not radiate back.
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.
For me it is visible that the Kirchhoff 's model (absolutely
black body) and the Michell's model (black hole) are
identical because they both execute one and the same
function – they absorb all falling radiation.
A black hole has a temperature within a few
millionths of a degree above absolute zero: T=0K.
/ Oxford. Dictionary./
A stellar black hole of one solar mass has a Hawking
temperature of about 100 nanokelvins. This is far less
than the 2.7 K temperature of the cosmic microwave background.
Previous Picture of the Day articles about black holes suggested that
the terminology used to describe “gravitational point sources”
is highly speculative: space/time, singularities, and infinite density
are abstract concepts, precluding a realistic investigation into
the nature of the Universe.
/ Oct 12, 2011. Black hole theory contradicts itself. By Stephen Smith /
My heretical idea:
The ‘black hole’ with thermodynamic temperature about -–--> T= 0K.
and Kirchhoff 's ‘absolutely black body’ are models of
a Homogeneous Energy Vacuum - Space between billions Galaxies.
By the way, Max Laue called the ‘absolutely black body’
as ‘ Kircchoff 's vacuum’.( vacuum -!)
Everybody think that conception of ‘ ideal gas’ is an abstract model.
But the temperature of ‘ ideal gas’ is T=0K and it is exactly as the
temperature of ‘black hole ‘. Therefore I say, that conception o
‘ ideal gas’ is model of vacuum and we can use all formulas of
‘ ideal gas’ to understand the pure vacuum: T=0K.
What are results of Vacuum’s absorption ?
If Quantum of light which got into area of
“absolutely black body- black hole – ideal gas - vacuum ”
and did not radiate back then the " thermal death " come.
And in the Nature it is not observed.
Therefore Max Planck, studying this area, came to a conclusion:
" Thermal death " condition can change when radiation of
quantum of light having own internal impulse h=Et will take place.
That is individual fluctuation of single quantum of light from vacuum.
In 1974 S. Hawking came up with theoretical arguments
showing that black holes are not really entirely black:
they can emit radiation.
That is collective – gravity fluctuation of light quanta from vacuum.
