G327.1-1.1 illuminates astronomers’
penchant for seeing what they
presume.
If you presume that gravity rules
the universe, you’ll look for
spherical symmetry and circular
forms. So a pulsar will appear to be
the core of a supernova at the
center of a spherical blast wave.
The collapsed core will blow off a
fast wind that will compress the
interstellar gas into a shock wave
and leave a bubble of relative
emptiness behind. Seen from our
distance, the shock wave will appear
as a circle.
But something must have got in the way of this pulsar: Astronomers
note that the pulsar and its “wind nebula” are off-center, they are moving
in opposite directions, and the pulsar’s x-ray emissions have a “comet-like”
shape. Lost in the glare from their brightly burning presumption is the sight
that the shock wave is not circular: both the “wind nebula” and the outer “blast
wave” are hexagonal.
In the Electric Universe, energy
doesn’t emanate from gravitational
“point sources” that impose a
spherical geometry on the energy’s
distribution. Electricity comes in
“cables” of Birkeland currents. They
distribute energy in ways more
like a lightning stroke or an
aurora. Instabilities impose
quasi-stable forms: “jet” and
“comet-like” ones are common, as are
hexagonal ones. See, for example,
the auroral currents around the
poles of
Saturn (item 4 in link) or the
hexagonal
craters left by discharges to
the surfaces of rocky planets and
moons.
Pulsar G327.1-1.1 is not
“off-center”: it is a pinch in an
x-ray jet emanating from a corner of
the “wind nebula” hexagon. Diocotron
instabilities, such as the swirls
seen in auroras, likely have spawned
small vortices in the toroidal
plasmoid that is the nebula, pulling
it into the hexagonal shape. Charge
may have built up in one of the
vortices, and a plasma-gun-like
mechanism has discharged the jet and
its pinch.
The pulsar hasn’t been precisely
located yet. But when found, it will
likely resolve into a
binary that has set up the
pulsar oscillation in the circuit
supplying its power.
