Missing dark matter located


Researchers discover that intergalactic space is filled with the unseen matter. By University of Tokyo, Kashiwa, Japan — Published: February 14, 2012
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 is distributed around galaxies.The new research concludes that galaxies have no definite “edges.” Instead, galaxies have long outskirts of dark matter that extend to nearby galaxies, and intergalactic space is not empty but filled with dark matter.It is well-known that there is a large amount of unseen matter called “dark matter” in the universe. It constitutes about 22 percent of the present-day universe while ordinary matter constitutes of only 4.5 percent. An important question still remains: Where is most of the dark matter in the universe? [Continue Reading…]

About

Avatar I'll be turning 18 soon and am a aspiring physicist. I'm working on a double major at the moment in physics and aerospace engineering and a life goal of mine is to help construct the next line of deep space vehicles.

I love all the sciences and the maths. History is a hobby of mine, and world cultures interest me to no end.

I am a skeptic by nature.
