The image above is a composite of two images taken 12 years apart. The object is
a supernova remnant that lies only about a thousand light-years from our
galaxy’s core. It has been named G1.9+0.3. The blue image, from 1985, is in
radio “light;” the orange image, from 2007, is in x-ray “light.” Clouds of gas
and dust that circle the galaxy's core obscure the "visual light" from G1.9, but
radio and x-ray wavelengths can penetrate those clouds.
Conventional theories understand G1.9 as the debris from an internally powered
star that
exploded. “The debris…crashes into surrounding material, generating a shell
of hot gas” that radiates x-rays and radio waves. By measuring the distance
between the two images, conventional theorists can calculate that the explosion
must have occurred about 140 years ago, making it the most recent supernova
explosion known in our galaxy. (It was not observed because the galactic clouds
hid it from view on Earth.) But this calculation is troubling because it results
in an “unprecedented expansion speed”—nearly 5% the speed of light—and the “most
energetic electrons” ever measured in a supernova remnant.
The discovery that space was permeated with cells and filaments of plasma
overturned the “empty space” cornerstone assumption. The discovery that
electromagnetic forces in plasma could be many times stronger than gravity
fractured the “gravity-only” cornerstone. The discovery that Birkeland-current
filaments could connect cosmic bodies into hierarchies of coupled circuits
threatened to replace the “internally powered” cornerstone with an “externally
powered” one. Only theorists’ dogmatic adherence to the obsolete assumptions
preserves them.
The Electric Universe understands G1.9 as an overload response of the central
star to a surge in the galactic circuit that powers it. The entire star was
engulfed in an exploding double layer (DL), a larger-scale version of the
exploding DLs that we call flares and coronal mass ejections (CMEs) on the Sun.
Most likely, the original star fissioned into two unequal bodies in order to
present a larger surface area that would accommodate the increased current. See
the electric description of
V838 Mon.
Exploding DLs accelerate as they expand, unlike conventional explosions whose
debris moves in an inertial response to the initial impulse. Calculations from
later debris movements to determine the time of explosion are therefore much
less reliable: G1.9 is apt to be more recent than 140 years.
Because DLs accelerate charged particles, fast electrons are expected. As well,
the electrons will spiral in the magnetic field and emit
synchrotron radiation. Conventional theorists calculate a “gas temperature”
from the energy of the radiation, assuming that the radiation comes from
particle collisions, as in a glowing iron bar. But synchrotron radiation has
little to do with temperature: the “gas” is really plasma, and the radiation is
powered by electricity, not heat.
Space age instruments have furnished abundant
data showing that supernovae remnants and their lower-energy
siblings, planetary nebulae, are not spherical “shells.” They
tend to have an hourglass shape, showing bipolar symmetry. The
circular ones only appear so because we are seeing them
along their axes.
