Let
us try something else. Quasars are way closer to us than we have
imagined and may actually be in our own galaxy. I have good reason
to think this anyway as the present theory depends on the extreme red
shifts exhibited for which present day astronomy accepts only one
explanation.
We
do that and it is a simple star cluster that is much the same age and
has entered the Quasar Stage close together. This obviously changes
the whole picture and demands an independent explanation for the
spectrum and the red shift. I can actually do this easily but will
leave it for the time been. It flows naturally from understanding
the implications of the higher order metrics I introduced in 2910 in
my paper in AIP's Physics Essays and the derivative Cloud Cosmology
unpublished as yet.
The
only other large groups out there are in fact local star clusters, so
it is completely reasonable to assert that they are the same thing.
Largest Structure
in Universe Discovered

Astronomers have
discovered the largest known structure in the universe, a clump of
active galactic cores that stretches 4 billion light-years from end
to end.
The structure is a
large quasar group (LQG), a collection of extremely luminous galactic
nuclei powered by supermassive central black holes. This
particular group is so large that it challenges modern cosmological
theory, researchers said.
"While it is
difficult to fathom the scale of this LQG, we can say quite
definitely it is the largest structure ever seen in the entire
universe," lead author Roger Clowes, of the University of
Central Lancashire in England, said in a statement. "This is
hugely exciting, not least because it runs counter to our current
understanding of the scale of the universe."
Quasars are the
brightest objects in the universe. For decades, astronomers have
known that they tend to assemble in huge groups, some of which are
more than 600 million light-years wide.
But the
record-breaking quasar group, which Clowes and his team spotted in
data gathered by the Sloan Digital Sky Survey, is on another scale
altogether. The newfound LQC is composed of 73 quasars and spans
about 1.6 billion light-years in most directions, though it is 4
billion light-years across at its widest point.
To put that
mind-boggling size into perspective, the disk of the Milky Way galaxy
— home of Earth's solar system — is about 100,000 light-years
wide. And the Milky Way is separated from its nearest galactic
neighbor, Andromeda, by about 2.5 million light-years.
The newly discovered
LQC is so enormous, in fact, that theory predicts it shouldn't exist,
researchers said. The quasar group appears to violate a widely
accepted assumption known as the cosmological principle, which holds
that the universe is essentially homogeneous when viewed at a
sufficiently large scale.
Calculations suggest
that structures larger than about 1.2 billion light-years should not
exist, researchers said.
"Our team has
been looking at similar cases which add further weight to this
challenge, and we will be continuing to investigate these fascinating
phenomena," Clowes said.
The new study was
published today (Jan. 11) in the Monthly Notices of the Royal
Astronomical Society.
