An
electromagnetic phenomenon on the
fringes of galaxy NGC 7793 is
confounding astronomers because they
insist on seeing it as a
gravitational superforce.
Explaining the jets of ionized
particles often seen erupting from
various objects in space ranks as
one of the most difficult tasks
facing modern astronomers. What
force can create highly energetic
particle emissions that span
distances measured in light-years?
What confines them into narrow
beams?
Hundreds of stellar jets have now
been observed, but the prevailing
theory of "compacted gravitational
point sources" exciting gas and dust
as they orbit does not address the
existence of collimated jets. There
is only one force that can hold such
a matter stream together over those
distances: magnetism.
The only way to generate that
magnetic confinement is through
electricity flowing through space.
In the past, astronomers observed
coherent filaments from so-called
“Herbig Haro" stars, some more than
12 light-years long. Charged
particles within the filaments were
thought to exceed velocities of 500
kilometers per second. The finely
knotted jets exceeded three times
the distance from our Sun to the
nearest star, Alpha Proxima.
According to ESO's recent
announcement, however, the jets from
the NGC 7793 microquasar are several
hundred light-years long.
Most researchers try to account for
narrowly confined jets by invoking
words like “nozzle” or "high
pressure," defying all that science
knows about the behavior of gases in
a vacuum. Some are even willing to
acknowledge that magnetic fields
might focus gases into narrow beams,
although there is a commonly held
opinion that magnetic fields are not
important.
Magnetic fields are only one part of
the story, and failure to realize
that electric currents create
magnetic fields has led many
physicists to model plasma in space
without considering the flow of
electricity. Nobel laureate Hannes
Alfvén, a pioneer in the field of
plasma cosmology, stated that plasma
is "too complicated and awkward” for
the tastes of mathematicians. It is
“not at all suited for
mathematically elegant theories” and
requires laboratory experiments.
Alfvén observed that the plasma
universe had become “the playground
of theoreticians who have never seen
a plasma in a laboratory. Many of
them still believe in formulae which
we know from laboratory experiments
to be wrong”. He thought that the
underlying assumptions of
cosmologists “are developed with the
most sophisticated mathematical
methods and it is only the plasma
itself which does not ‘understand’
how beautiful the theories are and
absolutely refuses to obey them”.
Stars are nodes in electrical
circuits. Electromagnetic energy
could be stored in the equatorial
current sheets surrounding them
until some trigger event causes them
to switch into a polar discharge.
The electric jet could receive its
energy from a natural
particle-accelerator, a "plasma
double layer" with a strong electric
field. Toroidal magnetic fields
would form because of the polar
plasma discharge, confining it into
a narrow channel.
Axial electric currents should be
flowing along the jet's entire
length. Only electric fields can
accelerate charged particles across
interstellar space.
