"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.

The computer simulation above shows dark matter is distributed, with high density regions appearing bright whereas dark regions are nearly, but not completely, empty.
