============…
What did I study from the article
1.
The vacuum can be a basic physical concept.
2.
The vacuum is full of various potential particles.
3
They can fluctuate in and out from vacuum.
3.
This process (long time ago) was named ‘vacuum fluctuations’
( -- the constant appearance and disappearance
of virtual particles in vacuum -- )
4.
The vacuum have a connection with "dark energy".
=====.
My conclusion.
Did I learn something new? Nothing new.
1
In 1928 Dirac said that vacuum full with virtual particles which
can appear from and disappear into this continuum
2
Dutch physicists Hendrik B. G. Casimir and B****** Polder proposed
the existence of the force and formulated an experiment to detect
it in 1948 while participating in research at Philips Research Labs.
The classic form of the experiment, described above, successfully
demonstrated the force to within 15% of the value predicted by the theory.

3.
We know that virtual particles can appear as a reason of
Vacuum fluctuation / polarization.
Vacuum polarization was observed experimentally in 1997 using
the TRISTAN particle accelerator in Japan.

http://en.wikipedia.org/wiki/Vacuum_polarization

My questions.
What mechanism the ‘virtual antiparticles’ use to do polarization?
What is mechanism of ‘ the self energy ‘ polarization?
Nobody tries to explain the mechanism of this process.
4.
But this article say me again that the conception of vacuum
is important for our understanding how the Universe works.
If vacuum itself can create particles, why we need ‘big bang’?
What was before ‘big bang’ or vacuum?
Did the ‘big bang’ explode in nothingness /vacuum or vice versa?
5.
The vacuum and "dark energy".
I say that vacuum itself is a "dark energy".
The Vacuum is a Homogeneous Space of the lowest
( the background ) level of Energy: E= 0 ( according to classical
thermodynamics theory ) or E= ∞ (according to quantum theory)

Dark Energy may be Vacuum

===.
Why do physicists refuse to take vacuum as a fundament of Universe?
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 /
My opinion.
It is true we cannot reach the zero temperature T=0K.
But just because we cannot reach this Vacuum’s
parameter it does not mean that it cannot exist.
#
If a tree falls in a forest and no one is around to hear it,
does it make a sound?
If unseen virtual antiparticles from vacuum can appear
and we can observe them as a real particles doesn’t it mean
that vacuum itself is absolute another Reference Frame which
has its own physical parameter – Absolute Zero: T=0K.
==.
Best wishes.

===================== .
P.S.
We are very interesting people: we accepted a big bang
in a nothing but refuse to accept the nothing as a fact.
