So Hot You're Cool, So Cool
You're Hot

Clouds of ionized gas and dust in
space are not heated up by gravity,
they are compressed by electrical
forces and emit synchrotron
radiation.A recent press
release from the European Southern Observatory explains that
this image shows “an expanding bubble of ionized gas,” shown
here in red. The bubble is assumed to be generated by the
ultraviolet radiation from a central star. It has caused a
“shock wave” that “sweeps up a layer of the surrounding cold
interstellar gas and cosmic dust. This layer becomes unstable
and collapses under its own gravity into dense clumps…, where
new stars are born.” The gas and dust has a temperature only 23
degrees above absolute zero (23K). This temperature is
determined by the submillimeter wavelengths of the radiation,
shown here in blue, and the assumption that the radiation is
produced by thermal processes.
Anyone who is familiar with plasma will immediately recognize
that “if it’s ionized, it ain’t gas.” And if it ain’t gas, a
shock wave is not likely to trigger gravitational instability
and collapse. The filaments and knots indicate the “pinch”
activity of the much greater electromagnetic forces of Birkeland
currents.
The roughly concentric and radial filaments prompt one to
suspect that we are looking “down the barrel” of an interstellar
Birkeland “cable,” which is pinching down in an hourglass form
to create and to power the central star. The instabilities are
not those of gravitation, which have never been shown
convincingly to cause collapse. They are plasma instabilities,
which have been shown in lab demonstrations not only to pull in
material and to compress it but also to set it spinning.
(Removing and imparting spin at exactly the right times in
exactly the right amounts is an insurmountable obstacle in
theories of gravitational collapse.)
From a plasma perspective, the temperature is also open to
question. Consensus astronomy talks a lot about unobservable
things like dark matter and dark energy, but it talks hardly at
all about observable synchrotron radiation, which is what most
celestial radiation is. Thermal radiation is produced by random
collisions of atoms, and its “peak” wavelength is a measure of
the temperature of the atoms. Synchrotron radiation is produced
by electrons moving along a magnetic field.
Moving electrons are also known as an electric current, and a
current moving along a magnetic field—a “field-aligned
current”—is also known as a Birkeland current. It’s therefore
not surprising that a universe composed almost exclusively of
plasma, which organizes itself into Birkeland currents, should
principally emit synchrotron radiation. Of course, synchrotron
radiation gives no indication of temperature: indeed, since it
comes from a non-random process, “temperature” is not even
defined.

SPECIAL NOTE - **New Volumes Available:
We are pleased to announce a new
e-book series
THE UNIVERSE ELECTRIC. Available now, the first volume
of this series, titled Big Bang, summarizes the failure of modern cosmology
and offers a new electrical perspective on the cosmos. At
over 200 pages, and
designed for broadest public appeal, it combines spectacular
full-color graphics with lean and readily understandable
text.
**Then second and third volumes in the series are now available,
respectively titled Sun and Comet, they offer
the reader easy to understand explanations of how and why these bodies
exist within an Electric Universe.
High school and college students--and teachers in
numerous fields--will love these books. So will a large
audience of general readers.
Visitors to the Thunderbolts.info site have often
wondered whether they could fully appreciate the Electric
Universe without further formal education. The answer is
given by these exquisitely designed books. Readers from
virtually all backgrounds and education levels will find them
easy to comprehend, from start to finish.
For the Thunderbolts Project, this series is a milestone.
Please see for yourself by checking out the new
Thunderbolts Project website, our leading edge in
reaching new markets globally.
