Is Hoag’s Object a Dense Plasma Focus?
What force swept away the stars and formed this 120,000
light-year-wide ring in space? This could be one of electrical
energy’s protean forms.
There are places in the cosmos where stars form up into ranks that stretch in
lines for thousands of light-years. Elsewhere, rings of stars can be found
encircling compact structures that have been measured at over 10,000 light-years
Art Hoag discovered the galaxy that bears his name in 1950 and by conventional
redshift-equals-distance calculations, it is approximately 183 megaparsecs away
in the constellation Serpens. The ring of “young” blue stars is notable, as is
the dense core and the hovering swarm of globular clusters that lie in the
center of the formation. There is an obvious swirling shape that radiates
outward in the same way as that from the
Cartwheel Galaxy in the constellation Sculptor. The filaments that connect
the core with the ring in the Cartwheel Galaxy are missing in Hoag’s Object,
although they could be radiating in dark current mode.
The Milky Way Galaxy contains over 200 billion stars in its spiral arms and its
nucleus. There have also been recent
observations by scientists from the Sloan Digital Sky Survey (SDSS)
indicating that a torus of additional stars is surrounding the Galaxy at a
distance of 120,000 light-years. Most of the stars discovered by SDSS are
invisible to visual platforms because they are in the same plane as the Galaxy,
itself. However, the stars have been detected using infrared and x-ray
instrumentation that can “see through” the obscuring dust. So, what causes
galaxies to develop rings?
According to Heidi Jo Newberg, associate professor of physics and astronomy at
Rensselaer Polytechnic Institute: “When we find large groups of stars formed
into rings it's an indication that at least part of our galaxy was formed by a
lot of smaller or dwarf galaxies mixing together.”
Her colleague in the project, Brian Yanny of FermiLab wrote: "This ring of stars
may be what's left of a collision between our Milky Way and a smaller, dwarf
galaxy that occurred billions of years ago."
His conclusion is that gravity from dark matter is sustaining the ring of stars
around the Milky Way. By definition, those same forces are what cause the more
dramatic structures like Hoag’s Object to appear – galactic collisions over
billions of years moderated by gravity and unknown energies.
Is there another way to address the issue that takes into account the
electricity that flows through the cosmos and the magnetic fields that it
fosters? It is possible that the stellar haloes
are actually examples of a
dense plasma focus penumbra with Hoag's Object being the most dramatic
example. Images taken from experiments using a “plasma gun” offer a direct
analogue to the “pinch zones” surrounding the discharge from Hoag’s Object.
In 1960, Hannes Alfvén published a paper in which he proposed a mechanism for
the formation of structures in space that does not depend on gravity alone. He
“The earth, the sun and many stars possess general magnetic fields. It is
possible that interstellar clouds are magnetized, that spiral arms have regular
magnetic fields, and that galaxies also have general magnetic fields. Even if
the views of different authors are still conflicting, it seems reasonably
certain that interstellar matter is usually magnetized. This makes is likely
that there should be some very general process which produces magnetic fields in
fluid bodies as different as the earth’s fluid interior, the stars, and
interstellar matter. The energy required for magnetization can easily be drawn
from the kinetic energy of internal motions, but the difficulty is to find a
workable mechanism from the production of magnetic fields.” (Alfvén, H. “On the
Origin of Cosmic Magnetic Fields”, Royal Institute of Stockholm, October 28,
dense plasma focus device, or “plasma gun” provides the precise mechanism by
which cosmic electric currents can influence the evolution and morphology of
space structures, whether they be moons or galaxies (See Peratt, A. L. and
Dessler, A. J. “Filamentation of Volcanic Plumes on the Jovian Satellite Io”.
Astrophysics and Space Science (ISSN 0004-640X), vol. 144, no. 1-2, May 1988, p.
Birkeland current filaments are the “transmission lines” through which
electricity is conducted in the universe. Just as the helical strands from the
Galaxy NGC 3079 are an indication that electricity is discharging from its
nucleus, the swirling toroids that constrain the “young” hot stars in the halo
of Hoag’s Object are a red flag to Electric Universe theorists.
One of the signature phenomena in a dense plasma focus is the helical strands of
energy that surround a powerfully radiating arc-mode discharge and a
dark-current torus. The strands are helical magnetic fields that confine the
electrified plasma and act like power lines in space – Birkeland current
filaments, in other words. That phenomenon is present In the plasma gun
discharge that makes up Hoag’s Object.
It may be that there are 28
filamentary strands (or 56, or 49 or some other number discussed
by Alfvén, Thornhill, Peratt and others) in the penumbral cloud
of stars and nebulae that have been energized by the gun – the
exact count is difficult to determine in the images that are
available. But, with the other factors and the way that
electricity behaves when it flows through magnetically confined
plasma, the Electric Universe model of galaxy formation appears
to have been lent further credence by this observation.
