Scientists Capture First Image of Dark Matter Web

Kristine Lofgren writes: Scientists have long suspected that the universe is woven together by a vast cosmic connector but, until now, they couldn’t prove it. Now, for the first time ever, scientists have captured an image of a dark matter bridge, confirming the theory that galaxies are held together by a cosmic web. Using a technique called weak gravitational lensing, researchers were able to identify distortions of distant galaxies as they are influenced by a large, unseen mass — in this case, a web of dark matter. In order to create a composite image that shows the dark matter web, scientists had to look at more than 23,000 galaxy pairs located 4.5 billion light-years away. “Results show the dark matter filament bridge is strongest between systems less than 40 million light years apart,” reports Phys.Org. The findings have been published in the journal Monthly Notices of the Royal Astronomical Society.
