Per facilitare l'eventuale discussione, porto l'attenzione sulla parte
teorica più interessante in quell'articolo. Nella 10. Discussion
dopo aver letto il background da "Pilot-wave theories are a family
of realist interpretations of quantum mechanics that conjecture that
the statistical nature of the formalism of quantum mechanics is due
to an ignorance of an underlying more fundamental real dynamics, and
that microscopic particles follow real trajectories over time just like
larger classical bodies do" fino a "The resultant trajectories that
photons follow are continuous real trajectories that are affected by
the pilot wave's probabilistic interference pattern with itself as it
undergoes constructive and destructive interference due to reflections
from the slits" è opportuno concentrarsi sul seguito:
In the approach used in the quantum vacuum plasma thruster (also
known as a Q thruster) supporting physics models, the zero point
field (ZPF) plays the role of the guiding wave in a similar manner
to the vacuum-based pilot-wave theories. To be specific, the vacuum
fluctuations (virtual fermions and virtual photons) serves as the
dynamic medium that guides a real particle on its way. Two recent
papers authored by members of this investigation team explored the
scientific ramifications of this ZPF-based background medium. The
first paper [18] considered the quantum vacuum at the cosmological
scale in which a thought experiment applied to the Einstein tensor
yielded an equation that related the gravitational constant to the
quantity of vacuum energy in the universe, implying that gravity
might be viewed as an emergent phenomenon: a long wavelength
consequence of the quantum vacuum. This viewpoint was scaled down
to the atomic level to predict the density of the quantum vacuum
in the presence of ordinary matter. This approach yielded a predicted
value for the Bohr radius and electron mass with a direct dependency
on dark energy. The corollary from this work pertinent to the
q-thruster models is that the quantum vacuum is a dynamic medium
and could potentially be modeled at the microscopic scale as an
electron-positron plasma. The quantum vacuum around the hydrogen
nucleus was considered in much more detail in the second paper [19].
Here, the energy density of the quantum vacuum was shown to
theoretically have a 1/r^4 dependency moving away from the hydrogen
nucleus (or proton). This 1/r^4 dependency was correlated to the
Casimir force, suggesting that the energy density in the quantum
vacuum is dependent on geometric constraints and energy densities
in electric/magnetic fields. This paper created a quasi-classical
model of the hydrogen atom in the COMSOL Multiphysics software
(COMSOL is not an acronym) that modeled the vacuum around the proton
as an electron-positron plasma. These analysis results showed that
the n = 1 to 7 energy levels of the hydrogen atom could be viewed
as longitudinal resonant acoustic wave modes in the quantum vacuum.
This suggests that the idea of treating the quantum vacuum as a
dynamic medium capable of supporting oscillations might be valid.
If a medium is capable of supporting acoustic oscillations, this
means that the internal constituents were capable of interacting and
exchanging momentum. If the vacuum is indeed mutable and degradable
as was explored, then it might be possible to do/extract work on/from
the vacuum, and thereby be possible to push off of the quantum vacuum
and preserve the laws of conservation of energy and conservation
of momentum. It is proposed that the tapered RF test article pushes
off of quantum vacuum fluctuations, and the thruster generates a
volumetric body force and moves in one direction while a wake is
established in the quantum vacuum that moves in the other direction.
Bye,
