The Models of Vacuum.
1.
A black hole is an idealized physical body ( with a mass of
three - six – ten times more than our Sun ) is a region of
spacetime from which nothing, not even light, can escape.
2.
A black body is an idealized physical body that can absorb
all incident electromagnetic radiation.

The result: from a ‘black body ‘not even light, can escape’
3.
Max Laue called ‘ Kirchhoff black body’ as ‘ Kirchhoff vacuum’
Why?
Because Vacuum is a space in which there is nothing material.
For example: according to QET then electron interacts
with vacuum he disappeared there. And therefore physicists
invented the mathematical " method of renormalization",
a method "to sweep the dust under the carpet" / Feynman./

The result: from a ‘vacuum ‘not even light, can escape’
#
My conclusion.
The ‘black body’, the ‘ black hole’ and the vacuum
can do one and the same work (completely absorb radiant
energy). It means that the ‘black body’ and the ‘ black hole’
are models of vacuum.

Another fact.
A black hole has a temperature within a few
millionths of a degree above absolute zero: T=0K.
/ Oxford. Dictionary./
And the vacuum has background cosmic temperature:
T= 2.7 K ----> T= 0K.
The background cosmic temperature (T= 2.7 K ----> T= 0K)
belongs to ‘ The Theory of Ideal Gas’ and therefore we can use
this theory for explaining ‘ The Theory of Vacuum’.

My conclusion.
The ‘black body’ and the ‘ black hole’ and
‘ The Theory of Ideal Gas’ are models of vacuum.

P.S.
If the ‘black body’ and the ‘ black hole’ and the vacuum can radiate
the quantum of light and electron – then the reason is the Vacuum’s
fluctuations / transformation / polarization. And this is ‘ a song from
another opera’. Because the Vacuum’s fluctuations / transformation /
polarization explains the Origin of the Material Existence.
