My own work
predicts that photonic energy leaving a black hole which is a misnomer can
decay into the particles recognized in our physical science and naturally
produce a mass which is attracted back toward the gravity well. I do not expect any mass to be accelerated
out of the well itself or much to be removed easily by light pressure although
that seems to be the present basis of theory.
Thus this is
once again unsurprising. Please note
that a core prediction of cloud cosmology is that matter is unraveled at the
event horizon and released as photonic energy to carry off gravitational
curvature at light speed. I will go
further and anticipate that the entire content of a black hole is an event
horizon that is in process of unwinding over a large expanse of time from our
perspective. It may be near instantaneous
in terms of the reference frame of the black hole.
This is good
news because it sharpens interest and doubts regarding our understanding of
Quasars which I think overdue.
New Type of
Quasar Found, Baffling Scientists
By Elizabeth Howell
The most luminous objects in the universe keep
getting more mysterious.
Astronomers have discovered a new type of quasar —
an incredibly bright galactic core powered by a supermassive black hole — that current theory fails to predict.
Models predict that a quasar's light and heat should
push nearby gas out from the center and toward the fringes of the host galaxy.
The newly found quasars do demonstrate this behavior, but, surprisingly, some
of the gas also appears to be falling back to the center, researchers said.
"Matter falling into black holes may
not sound surprising," study lead author Patrick Hall, an astronomer at
York University in the United Kingdom, said in a statement. "But what we
found is, in fact, quite mysterious and was not predicted by current
theories."
So far, astronomers have found 17 of these objects,
which are thought to make up just 0.01 percent of all quasars.
Gas flow in and around quasars can be calculated by
examining its Doppler shift, or the change in the wavelengths of light that are
produced as the gas moves. On Earth, humans can hear the Doppler shift in
action when a car toots its horn as it zooms by. As it comes towards you, the
sound waves are compressed and the horn's pitch sounds higher. After it passes,
the sound waves lengthen and the pitch drops.
Particles of gas in a distant galaxy emit light at
expected wavelengths. This changes as the gas moves toward Earth or away from
it. Gas receding from Earth is shifted to the red edge of the light spectrum
(which has longer waves), while gas moving toward Earth appears more blue.
Quasar light is easy to track because it is
astonishingly bright, producing "enough light to be seen across the observable
universe," York University officials said in a statement. The appearance
of these newfound quasars, however, generated a mystery.
"The gas in the disk must eventually fall into
the black hole to power the quasar, but what is often seen instead is gas blown
away from the black hole by the heat and light of the quasar, heading toward us
at velocities up to 20 percent of the speed
of light," Hall
said.
"If the gas is falling into the black hole,
then we don't understand why it's so rare to see infalling gas," he added.
"There's nothing else unusual about these quasars. If gas can be seen
falling into them, why not in other quasars?"
One theory suggests the gas is not descending into
the black hole but instead is circling it after the quasar pushes it away. This
means that some particles of gas in the galaxy would be moving toward Earth,
while others are moving away.
"To make an analogy: Imagine an ant on a
spinning merry-go-round, crawling from the center to the edge," Hall said.
"You will see the ant moving toward you about half the time and away from
you about half the time. The same idea could apply to the gas in these quasars.
In either case, the gas in these quasars is moving in an unusual fashion."
Astronomers found the quasars using data from the
Sloan Digital Sky Survey (SDSS-III), which examines large swaths of the sky.
Scientists expect quasar models will have to be revisited, so the researchers
plan follow-up surveys using the Gemini Observatory.
The research was published Sept. 1 in the Monthly
Notices of the Royal Astronomical Society.
