Does somebody know what Vacuum is ?

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 /

‘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? ‘

Can Perfect Vacuum as a ' Nothing' as ‘ an Infinite Space’ as
an Absolute Reference Frame have Concrete Physical Properties ?

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.

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 ?
