Cosmic Web of Dark Matter Host Massive Galaxy Clusters Spanning One Billion Light Years



For the first time astronomers at the University of Edinburghand University of British Columbia have mapped dark matter on the largest scale ever observed. Their findings reveal a Universe comprised of an intricate cosmic web of dark matter and galaxies that spans more than one billion light years, with the densest regions of the dark matter cosmic web hosting massive clusters of galaxies. 

An international team of researchers achieved their results by analysing images of about 10 million galaxies in four different regions of the sky. They studied the distortion of the light emitted from these galaxies, which is bent as it passes massive clumps of dark matter during its journey to Earth.

Observations show that dark matter in the Universe is distributed as a network of gigantic dense (light) and empty (dark) regions, where the largest dense regions are about the size of several Earth moons on the sky. 

Galaxies included in the survey are typically six billion light years away. The light captured by the telescope images used in the study was emitted when the Universe was six billion years old – roughly half the age it is today.

The team's result has been suspected for a long time from studies based on computer simulations, but was difficult to verify owing to the invisible nature of dark matter. This is the first direct glimpse at dark matter on large scales showing the cosmic web in all directions.


"It is fascinating to be able to 'see' the dark matter using space-time distortion," said Ludovic Van Waerbeke, from the University of British Columbia. "It gives us privileged access to this mysterious mass in the Universe which cannot be observed otherwise. Knowing how dark matter is distributed is the very first step towards understanding its nature and how it fits within our current knowledge of physics."

"By analysing light from the distant Universe, we can learn about what it has travelled through on its journey to reach us," said Dr Catherine Heymans, a Lecturer in the University of Edinburgh's School of Physics and Astronomy. "We hope that by mapping more dark matter than has been studied before, we are a step closer to understanding this material and its relationship with the galaxies in our Universe."
"Over the next three years we will image more than 10 times the area mapped by CFHTLenS, bringing us ever closer to our goal of understanding the mysterious dark side of the Universe,"observed Koen Kuijken, from Leiden University.

There is no such thing as dark matter, time is slowing down.

The dark matter map looks exactly the same as the cellular fractal filamentary plasma web. The dense white regions are aligned looking through long vast cosmic plasma filaments connecting together galaxies to form clusters and superclusters. The black regions prove that dark matter is phony and invented because the electromagnetic forces are still becoming learned. The universe is 99.9% plasma says Gallagher of NASA on his website. This means EM forces in outer space vacuum shape and form galaxies without phony dark matter. Still my incredible evidences and stories on my blog at:


If time is slowing down why am I always late?

Also a question on expansion. If space is/was still expanding and every atom in the cosmos that we can see/detect was expanding along with it, would we be able to tell? Is it possible that we all grew by .0001% by the time it took me to type this?

Wow...I am amaze how did they get such photo, congrats for a great job.

This is the weirdest collection of reader responses on TDG yet. Lol.

No, you didn't grow any taller because of the expansion of the universe. They say only galaxies are expanding apart from each other, accelerating faster by dark energy, but the size of each galaxy remains the same. This is merely 5% of the known visible universe observed, and is a far cry when you believe like me that there is no ultimate sized supercluster, but hyperclusters and superduperhyperclusters...making the universe far larger and older then the baby universe of the big bang jerks who say the universe is only 3 times older then the earth parasitic planet inhabitants.



I dont know, your reply sounds too blinded by anger and prejudice to accept any other possibilities. Also you sorta misunderstood the question. But thanks for trying.

In my opinion, it needs more studies to prove what it needs to prove.
