Presumptive Proplyds

Are the elongated blobs of
gas and dust observed within various
nebulae the signature of star-birth?
A recent
press release from the
European Space Agency (ESA)
highlights images from the Hubble
Space Telescope that are said to
reveal "baby stars" called proplyds
(PROto-PLanetarY Disk) within the
Orion Molecular Cloud complex. Such
dusty aggregations are thought to be
where gravity is pulling wispy gases
together until they reach pressures
sufficient to ignite thermonuclear
fusion.
According to the Nebular
Hypothesis, the remaining clumps of
dust and gas that are not absorbed
by the newly minted star swirl
around, attracting more stray bits,
until they also condense, but this
time into planets. It is said that
our own Solar System was created in
a similar "stellar nursery" billions
of years ago.
A
previous announcement
from ESA's XMM-Newton x-ray
telescope revealed “flowing plasma”
at over one million Kelvin, along
with x-ray emissions, in the same
regions where the supposed star
factories are located. Astronomers
were surprised by the discovery,
because no one expected to find “hot
gas” within a cloud of cold vapor.
At last count, over 700 new stars
are said to be forming inside the
nebula. Although stars of any class
are thought to be x-ray sources, no
nebula is supposed to possess the
intrinsic energy necessary to
generate them.
The investigators believed that
they knew where the plasma and
x-rays came from, the collision of
“high velocity winds emitted by
stars.” In other words, in the heart
of the nebula, stellar winds cause
“shock waves” to raise the
temperature in the environment to
millions of degrees. The plasma they
identified is really meant to refer
to hot gas with no reference to its
electrically active component.
Star-forming regions are
conventionally associated with high
frequency light from their active
regions. Gamma rays, x-rays, and
extreme ultraviolet shine from the
"cosmic eggs", and appear to be the
glowing tips of condensed gas balls.
One of the most iconic images in
modern astrophotography is the
famous "Pillars
of Creation" in the
Eagle Nebula. The tops of
the clouds, with their Q-tip
structures, x-ray radiation, and
compact shapes are also deemed to be
stellar nurseries, where standard
theories meet colorful pictures.
That gas can be heated until it
gives off x-rays without stripping
electrons from the nuclei, or that a
“wind” of ionized particles is not
an electric current, or that the
only way for charged particles to
accelerate is through shock waves is
seriously limiting. It betrays a
reactionary viewpoint despite the
evidence of observations.
The Electric Star hypothesis
resolves many of the distorted
opinions that arise from
misunderstanding the role of plasma
and electric fields in space. Rather
than kinetic activity (heated gas),
the Orion Nebula’s radiant
emanations result from electric
currents.
Electric discharges in a plasma
cloud create double layers, or
sheaths, along the current axis.
Positive charge builds up on one
side and negative charge on the
other. An electric field develops
between the sides, and if enough
current is applied the sheath glows,
otherwise it is invisible. Electric
currents flow along the sheaths. In
plasma, the currents spiral into
filaments, or double layer tubes.
The filaments attract each other,
but rather than merging they spiral
around, gradually pinching down into
arc mode discharges.
Electric sheaths that are
normally invisible are "pumped" with
additional energy from galactic
Birkeland currents in which they are
immersed. The excess input power
pushes them into "glow mode", while
increased flux density draws matter
from the surrounding space into
filaments that ignite the nebular
"gases" electrically.
It is in this way that stars are
born. Gravity, although it plays a
small role in stellar evolution, is
far too weak a force when compared
to an electric field and ionized
particles.
