Does somebody know what Vacuum is ?
1.
Book : ‘Dreams of a final theory’ by Steven Weinberg. Page 138.
‘ It is true . . . there is such a thing as absolute zero; we cannot
reach temperatures below absolute zero not because we are not
sufficiently clever but because temperatures below absolute zero
simple have no meaning.’
/ Steven Weinberg. The Nobel Prize in Physics 1979 /
2.
‘If we were looking for something that we could conceive
of as God within the universe of the new physics,
this ground state, coherent quantum vacuum might be
a good place to start.’
/ Book ‘The quantum self ’ page 208 by Danah Zohar. /

And Paul Dirac wrote:
‘ The problem of the exact description of vacuum, in my opinion,
is the basic problem now before physics. Really, if you can’t correctly
describe the vacuum, how it is possible to expect a correct description
of something more complex? ‘

there was a BBC documentary called everything and nothing (done in two parts). The "nothing" documenary was awesome. It used to be online but i can't find it at the moment.

A vacuum picks up dirt off the floor. Mine sucks.

Mine too! I call it Monica.

Can Perfect Vacuum as a ' Nothing' as ‘ an Infinite Space’ as
an Absolute Reference Frame have Concrete Physical Properties ?
Socratus
=.
One Concrete Physical Properties of Vacuum is Absolute Zero.
What is Absolute Zero ?
Classic Physics says: It is a dead space.
Quantum Physics says: It is not a dead space.
There are ‘ Virtual Particles’ exist.
What is Absolute Zero ?
=.

P.S.
What is Absolute Zero ?
Where is a wise answer and where is a fool answer if these
two theories ( Classical and Quantum theories) are correct ?

Vacuum, my opinion: T= 0K, E= ∞ , p = 0, t = ∞ .
=.
Vacuum is a Kingdom of Coldness.
Vacuum is an Infinite Continuum.
Vacuum doesn’t have ‘ Time ‘, It is Eternal.
Vacuum’s density is zero.
Vacuum is an Infinite Energy Continuum.
Vacuum is the zero point of everything.
Vacuum is a Kingdom for everything.
Vacuum is a maximum ‘entropy’.
Vacuum is simply logical distance between things.

Can you not use a dictionary? Vacuum is just space that has no matter in it. It's not necessarily at absolute zero, it may have radiation in it, which means it can be at a non-zero temperature, and it doesn't contain infinite energy. You're inventing mysteries where there aren't any.

I know what a vacuum isn't...

Einstein and I.
=.
Einstein, you was mistaken using your Gravitation theory
to the all Universe as a whole.
The Gravitation theory doesn’t work in the Universe as a whole.
The Gravitation theory is a local theory.
Why?
Because the detected material mass of the matter in the
Universe ( the cosmological constant / the critical density)
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 sphere and therefore our
Universe as whole must be ‘open’, endless, infinite.
The Universe as a whole is an Infinite Pure Vacuum: T=0K.
More concrete:
§ 1. Vacuum: T= 0K, E= ∞ , p = 0, t =∞ .
=.
We have two (2) Worlds: Vacuum and Material and we need
to understand their interaction.
