“Our entire understanding of the Universe, even how we interpret the light we see from stars and galaxies, would be affected if the Universe were not even on large scales. By looking at how the WiggleZ galaxies are distributed in space on scales up to 930 million light years, we find that they are very close to homogeneous, meaning there is no large-scale clustering. So we can say with a high degree of certainty that our picture of the large-scale Universe is correct,” said Morag Scrimgeour of the International Centre for Radio Astronomy Research (ICRAR).
The current model is based on Einstein's equations assuming everything is smooth on the largest scales. If matter were instead clumpy on very large scales, then the entire model would need to be rethought.This image above is a slice from a large simulation called 'GiggleZ' which complements the WiggleZ survey. It shows a snapshot of the large-scale matter distribution as studied in Morag Scrimgeour's research.
Cosmologists agree that on 'small' scales (tens of millions of light years), matter in the Universe is highly clustered. So the 'standard model' can only hold true if the Universe transitions to an even distribution of matter (homogeneity) on larger scales, irrespective of the viewing direction. However, some scientists have recently argued that the entire Universe never becomes homogenous, and that it is clustered on all scales, much like one of Mandelbrot's famous 'fractals' (a snowflake is a good example of a fractal). If the Universe has properties similar to a fractal, our description of space and time is wrong, and our understanding of things like Dark Energy is deeply flawed.
Using the Anglo-Australian Telescope, Ms Morag Scrimgeour has found that on distance scales larger than 350 million light years, matter is distributed extremely evenly, with little sign of fractal-like patterns.*“We used a survey called WiggleZ which contains more than 200,000 galaxies, and probes a cosmic volume of about 3 billion light years, cubed,” Ms Scrimgeour explains “This makes it the largest survey ever used for this type of measurement of the large scale Universe.”
This finding is extremely significant for cosmologists as it confirms that the tools being used to describe the Universe are the right tools for the job after all. Had evidence been found confirming large-scale fractals, it would have left cosmologists without a working model for the Universe, sending them back to the drawing board to painstakingly adjust theories.
ICRAR is a joint venture between Curtin University and The University of Western Australia providing research in the field of radio astronomy. ICRAR researchers are playing an important role in the design and ultimate success of the Square Kilometre Array radio telescope project.
This project is part of 'The Dark Universe' theme of the ARC Centre of Excellence for All-sky Astrophysics (CAASTRO). For more information, please see www.caastro.org.

During this 10-minute exposure one of the team spelt out the survey name with a torch, while walking along the telescope catwalk 8 stories above the ground. In the background we can see dust and star clouds of the Milky Way galaxy (upper right) and our neighbor galaxy, the Small Magellanic Cloud (upper left).

And no one beleived me either when I said it was a web matrix,now a web matrix fabic overlayed & "held together" by a greater" created web................
Posted by:linda loughlin |August 23, 2012 at 09:12 AMComplete utter liars !!! This is written to deceive the public and purport the phony big-bang dark matter missing gravity cosmology.
The universe is clumpy, with the majority of matter in the Zone of Avoidance, which is the plane aligned with our galaxy. All other studies show clumps, and the filamentary structure is fractal electromagnetism.
See correct interpretations at the Electric Universe, and at holographicGalaxy.blogspot.com
I am sure this will jump back and forth a few more times in the next few years.

Posted by:babaloo |August 23, 2012 at 09:23 PMHolo: you are a loon... most of the matter concentrated in the zone of avoidance? ARE YOU BLOODY KIDDING ME MAN!?!?! you choose the only spot in the night sky where we can't see past as being proof of the universe being clumpy... good lord

Posted by:Holo |August 24, 2012 at 03:51 AMWith a recent report that, if shrunk to the size of a beach ball, the sun would display variations in peaks and troughs on its surface of less than the breadth of a human hair, smoothness seems to be an interesting facet of universal physics.
Posted by:Hamymac |August 24, 2012 at 05:04 AM@ holo Don't mind the haters, its obvious that you're far more intelligent than that quack Albert Einstein. You have proven it, and now the world knows you're smart.
Posted by:Matthew |August 24, 2012 at 03:14 PMhumm,aint it all relative? that picture looks like synaps of brain neurons...on the microscopic scale. on the cosmic level it looks the same...dark energy. is grey matter.or consciousness waiting to be absorbed by a big black hole so it can be excreted out into a white hole.thats when re creation starts over again
Posted by:ninth octave |August 24, 2012 at 03:36 PMi don`t believe we`re in the position to say Einstein was right. Nor in the next 100 years form now.
