The
problem that I have with this interpretation is that it is been
observed simultaneously across thousands of light years at least.
This is either absurd or plausibly, these galaxies are vastly closer
to us than we had ever imagined. Recall that our measurement
protocol is dependent on one rather iffy assumption that has been
producing a number of uncomfortable inferences over the years.
For
the record, my own work explains the Red shift as an artifact of the
age of the universe itself and unrelated to galactic velocity which
is in fact generally modest and over the whole likely neutral. It
should still give the same results.
We
are still dealing with vast distances so just what could a galactic
core actually be? Is it really less that a dozen light years across
which is the implied inference? Again are our metrics quite right?
I suspect otherwise and what else have we got wrong?
Monster Black Hole
Burp Surprises Scientists

LONG BEACH, Calif. –
Astronomers have discovered what appears to be colossal belch from a
massive black hole at the heart of a distant galaxy. The outburst was
10 times as bright as the biggest star explosion, scientists say.
The potential
super-sized black hole burp find came as astronomers studied the
galaxy NGC 660, which is located 44 million light-years away in the
constellation Pisces.
"The discovery
was entirely serendipitous. Our observations were spread
over a few years, and when we looked at them, we found that one
galaxy had changed over that time from being placid and quiescent to
undergone a hugely energetic outburst at the end,"
study researcher Robert Minchin of Arecibo Observatory in Puerto Rico
said in a statement.
To determine whether the outburst was from a supernova —
the explosive end of a star — or the galaxy's core, the
researchers used the High Sensitivity Array, a global network of
telescopes that includes the Very Long Baseline Array, the Arecibo
Telescope, the NSF's 100-meter Green Bank
Telescope, and the 100-meter Effelsberg Radio Telescope in
Germany.
Instead of an
expanding ring of material suggesting a supernova event, the
researchers found five locations with bright radio emissions
clustered around the galaxy's core.
"The most likely
explanation is that there are jets coming from the core, but they are
precessing, or wobbling, and the hot spots we see are where the jets
slammed into the material near the galaxy's nucleus," said Chris
Salter, also of the Arecibo Observatory.
Those jets, the
researchers said, would mean the outburst likely came from a
supermassive black hole at the heart of galaxy NGC 660. As the black
hole devours dust and mass, it pulls a whirling disk of matter into
its heart that spews jets of particles as it is consumed.
Supermassive black
holes are colossal structures at the cores of galaxies that are
between millions and billions of times as massive as the sun. They
are much larger than stellar-mass black holes, which are created from
the deaths of giant stars and can contain the mass of about 10 suns.
