Does somebody know what Vacuum is ?
No, we don’t know what Vacuum is.

‘ 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? ‘

The most fundamental question facing 21st century physics will be:
What is the vacuum? As quantum mechanics teaches us, with
its zero point energy this vacuum is not empty and the word
vacuum is a gross misnomer!

“ Unfortunately neither the concept of space nor of time is well defined,
resulting in a dilemma. If we don't know the character of time nor of space,
how can we characterize either? “

"Now we know that the vacuum can have all sorts of wonderful effects
over an enormous range of scales, from the microscopic to the cosmic,"
said Peter Milonni
from the Los Alamos National Laboratory in New Mexico.

‘ All kinds of electromagnetic waves ( including light’s)
spread in vacuum . . . . thanks to the vacuum, to the specific
ability of empty space these electromagnetic waves can exist.’

So, we know that the vacuum is very important conception in physics
and nature, but . . . but . . . we don’t know what vacuum is, and therefore
is possible to have many speculations including metaphysical too.
For example: Danah Zohar wrote:

‘It might even give us some ground to speculate that
the vacuum itself (and hence the universe) is ‘conscious’.
/ Book ‘The quantum self ’ page 208. /

‘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. /

The question is:
How is it possible to prove Zohar’s metaphysical confirmation
with physical laws and formulas?
