"No Empty Space in the Universe" --Dark Matter Discovered to Fill Intergalactic Space
New research concludes that instead of "edges," galaxies have long outskirts of dark matter that extend to nearby galaxies and that the intergalactic space is not empty but filled with dark matter.Researchers at the University of Tokyo’s Institute for the Physics and Mathematics of the Universe (IPMU) and Nagoya University used large-scale computer simulations and recent observational data of gravitational lensing to reveal how dark matter --which makes up about 22 percent of the present-day universe --is distributed around galaxies in a clumpy but organized manner.
Only recently, images of millions of galaxies from Sloan Digital Sky Survey (SDSS) made it possible to derive an averaged mass distribution around the galaxies. Earlier in 2010, an international research group led by Brice Menard then at University Toronto and Masataka Fukugita at IPMU used twenty four million galaxy images from the Sloan Digital Sky Survey (SDSS) and successfully detected gravitational lensing effect caused by dark matter around the galaxies. From the result, they determined the projected matter density distribution over a distance of a hundred million light-years from the center of the galaxies.
Masataka Fukugita and Naoki Yoshida at IPMU, together with Shogo Masaki at Nagoya University, used very large computer simulations of cosmic structure formation to unfold various contributions to the projected matter distribution. They showed that galaxies have extended outskirts of dark matter, well beyond the region where stars exist.
The dark matter distribution is well organized but extended to intergalactic space, whereas luminous components such as stars are bounded within a finite region. More interestingly, the estimated total amount of dark matter in the outskirts of the galaxies explains the gap between the global cosmic mass density and that derived from galaxy number counting weighted by their masses.
A long standing mystery on where the missing dark matter is has been solved by the research. There is no empty space in the universe. The intergalactic space is filled with dark matter.

Wow.

So a computer simulation concludes the mystery? awesome.

Computers dont know everything.

We're going to need a dark matter drive.

If dark matter is matter, why are there no dark matter stars?

this dark matter they cannot explain, but it shows that electric and magnetic fields are causing large-scale strucures to form and shape the universe.They used to say galaxies are not connected by electric jets and magnetic fields, but now we see that galaxies are connected together into this filamentary web biosphere cosmic web, which is known to be hot plasma filaments of ionized gas. The universe is 99.99% plasma, not gravity by asteroids and planets. Oil and water do not mix, not any better then gravity by dark matter in zero gravity electromagnetic vacuum environment

maybe dark matter is a computer itself maybe its god o.o

The headline and article are wrong because there is indeed empty space in the Universe and it appears that the computer models are flawed.
"Empty space" has been directly observed by radio astronomers, who found the biggest hole ever seen in the universe. The void, which is nearly a billion light years across, is empty of both normal matter and dark matter. The finding challenges theories of large-scale structure formation in the universe.
Computer simulations that recreate the formation of clusters and super-clusters have never seen voids of this size. That could be because modellers have not simulated large enough volumes to see such a void, says Rudnick. If they did, maybe a void would emerge.

If it fills every 'empty' space...we should find a way to exploit that for star travel; maybe dark matter is a medium through which FTL travel is possible? Just a thought.

If only we could capture the dark matter and use it as a propellant,
we could travel the universe and never fear for the lack of energy.
Maybe this will replace nuclear energy on earth?

does this mean there is no such thing as nothing? That there is in fact always SOMETHING

There is no dark side in the moon, really. As a matter of fact it's all dark.

the vacuum is never empty but filled with virtual particles having very brief existences. These form fractal patterns at infinite quantum scales to macro-scale stars, galaxies, hyperclusters. Swarming streaming particles form stars that form galaxies that swarm and stream to form superclusters. the big-bang is nonsense as time is revelant to size and motion of the observer.

Something is full of something but it is not the universe and dark matter.

I had a long hard look at all these comments, and the only thing I can say is; WTF!

the biblical god does exist. when asked in genesis, god tells Moses that god is light, life and love. which of you brilliant scientists will deny the existence of those things. only a stupidly arrogant mass of atoms that can think could possibly deny the existence of god. oh, these brilliant scientists have to deny what they themselves are to deny god. but they are too dumb or too arrogant to realize that our existence is comprised of those things. the only reason we know anything is the love, put together with light, add a thought and voila, life. what do you think you are?
Posted by: john | February 15, 2012 at 10:41 AM
@ John .. So when we create light or life we are creating god? Interesting.

Hello,
I am writing a book referring to the holographic universe. Would it be possible to use your picture showing these filaments?
Thank you in advance for your reply.
