[Snip]
The snip you provide seems irrelevant to the issue at hand. The space
between conductive plates having certain wavelengths excluded therein is
analogous to the space beyond the glass on the side opposed to the light
source also having certain wavelengths excluded from it. A lower frequency
portion of a spectrum is excluded in both cases. The analogy holds
especially well with regards to the most relevant fact that in neither case
is any frequency or energy "up-converted". Some frequencies from a broad
spectrum are merely excluded in both cases. No frequencies are changed.
Energy is only excluded, not transformed. The term "up-converted" then
merely creates confusion. It draws an unnecessary cloak of complexity, or
possibly just confusion, over something readily taught and understood in 8th
grade science class.
Horace, [Reply]
The propagation of visible light radiation is attenuated in
a filter but is transformed in a Casimir cavity.
The Casimir effect is not a force that interacts with the zero point field.
It is a result of the action of the zero point field on matter, its
isotropic nature, and its cubic energy distribution. It is also notable
that the Casimir force does not require conductive surfaces to manifest, but
that is a side issue, irrelevant in this case and certainly not an issue
that breaks the analogy at hand. If you have any credible reference that
says zero point field frequency or energy is actually up-converted by or
within Casimir cavities then will you please provide it?
[Reply] The Wikipedia *does define conducting metals* placed within a few
micrometers and there is a link to vacuum expectation value
<http://en.wikipedia.org/wiki/Vacuum_expectation_value> which may put
things in terms You are more familiar with like Fermion fields.
>From Wikipedia: In physics <http://en.wikipedia.org/wiki/Physics> , the
Casimir effect and the Casimir-Polder force are physical forces
<http://en.wikipedia.org/wiki/Force_(physics)> arising from a quantized
field <http://en.wikipedia.org/wiki/Quantum_field_theory> . The typical
example is of two uncharged <http://en.wikipedia.org/wiki/Electric_charge>
metallic plates in a vacuum <http://en.wikipedia.org/wiki/Vacuum> , placed a
few micrometers apart, without any external electromagnetic field
<http://en.wikipedia.org/wiki/Electromagnetic_field> . In a classical
<http://en.wikipedia.org/wiki/Classical_electromagnetism> description, the
lack of an external field also means that there is no field between the
plates, and no force would be measured between them.[1]
<http://en.wikipedia.org/wiki/Casimir_effect#cite_note-0> When this field
is instead studied using quantum electrodynamics
<http://en.wikipedia.org/wiki/Quantum_electrodynamics> , it is seen that the
plates do affect the virtual photons
<http://en.wikipedia.org/wiki/Virtual_particle> which constitute the field,
and generate a net force[2]
<http://en.wikipedia.org/wiki/Casimir_effect#cite_note-1> -either an
attraction or a repulsion depending on the specific arrangement of the two
plates. This force has been measured, and is a striking example of an effect
purely due to second quantization
<http://en.wikipedia.org/wiki/Canonical_quantization> .[3]
<http://en.wikipedia.org/wiki/Casimir_effect#cite_note-2> [4]
<http://en.wikipedia.org/wiki/Casimir_effect#cite_note-3> However, the
treatment of boundary conditions in these calculations has led to some
controversy.[5] <http://en.wikipedia.org/wiki/Casimir_effect#cite_note-4>
Overview
The Casimir effect can be understood by the idea that the presence of
conducting metals and dielectrics <http://en.wikipedia.org/wiki/Dielectric>
alters the vacuum expectation value
<http://en.wikipedia.org/wiki/Vacuum_expectation_value> of the energy of
the second quantized electromagnetic field.[9]
<http://en.wikipedia.org/wiki/Casimir_effect#cite_note-8> Since the value
of this energy depends on the shapes and positions of the conductors and
dielectrics, the Casimir effect makes itself manifest as a force between
such objects.
A bit outside the scope of all this is the fact the zero point field may not
exist at all. The Casimir force could just be the result of van der Walls
forces, which are not thought by everyone to be a result of the zero point
field. It is merely a hypothesis.
[Reply] NOW we are talking! I had numerous
exchanges with Thomas Prevenslik who champions this sentiment when I first
started my quest back in October 08, I became aware of the controversy
surrounding the existence of Casimir force and vacuum fluctuations into what
I simplified as "push" vs "pull" camps. I was originally in the push camp
associated with the Casimir model but Thomas convinced me that the
electrostatic "pull" could be induced by up-conversion of IR to VUV in
obedience with conservation of energy. As for up-conversion see ABSTRACT
below from Casimir force
<http://www.geocities.com/sonoluminescence2004/casimir.PDF> - neutral or
electrostatic? The controversial extension I have applied to his "up
conversion" was inspired by Naudts and Bourgoin. I am proposing the "way"
nature "up converts" is relativistic - no attenuation, no transducer, We
have confined the variable and conspired events such that a Lorentz
contraction (or temporal excursion) becomes the path of least resistance to
accomplish conservation of energy.
Since the suppressed IR radiation cannot escape the gap surfaces, the
only way EM energy may be conserved within cavity QED constraints is for the
equivalent amount of suppressed IR
energy to be gained in the gap. But the gap is resonant at VUV frequencies,
and therefore the conservation of EM
energy may be said to induce the frequency up-conversion of IR radiation to
the VUV. Indeed, if Casimir had
included the VUV energy or its IR equivalent in his derivation, he would
have shown there is no force between the
plates. But there is an electrostatic force. For different material
geometry, the VUV radiation causes electron
emission leaving a positive charge on one gap surface while the other
surface gains electrons and charges negative.
Steady heat flow from the environment at ambient temperature maintains the
thermal kT energy of the atoms to
provide a constant source of charge. Permanent adhesion in MEMS devices is
caused by ESD from the high electric
fields developed in the gap. Because of dependence on thermal kT energy, the
Casimir force in the modified theory
does not exist at absolute zero.
Lastly you again use the phrase "vacuum flux", but you have still not
defined it. Flux of what in or from the vacuum? In fact, what do you mean
by "flux"?
[Reply] I mean vacuum fluctuations aka virtual particles the same as those
Puthoff proposes wink into and out of existence and which keep the electron
orbital from decaying into the nucleus. I prefer to call them fluctuations
(flux) because I am focused on their wave nature, If they exist they
represent the canvas that nature stretches performing a Lorentz contraction
to keep energy balanced. Presently they are an unproven mechanism but they
still demonstrate a "force" needed to balance Puthoffs' atomic model and
regardless if the model is true or not it becomes a place holder, as such it
can be used as a tool. Note the "push" and "pull" camps both agree that an
"exclusion zone" exists between the plates if permanently braced apart and I
was only able to proceed forward after my communication with Thomas by
remaining focused on this common ground.
