'First ever image of dark matter' revealed

April 13, 2017 | Comment icon 2 comments


Scientists in Ontario have compiled an image of dark matter filaments connecting two galaxies together.
The existence of this enigmatic form of matter, which is thought to account for up to 85% of the mass of the universe, remains one of the most important unsolved mysteries in modern physics.

Even observing dark matter directly has proven to be a challenge, but now two researchers at the University of Waterloo believe that they have succeeded in creating a composite image showing dark matter filaments bridging two galaxies located 4.5 billion light years away.

The impressive image took advantage of a technique known as weak gravitational lensing which causes the appearance of distant objects to warp slightly under the influence of an unseen mass.

"For decades, researchers have been predicting the existence of dark-matter filaments between galaxies that act like a web-like superstructure connecting galaxies together," said study author Mike Hudson, an astronomy professor at the University of Waterloo.

"This image moves us beyond predictions to something we can see and measure."

Great find even if it doesn't wind up being dark matter.

just about to post same lol, what is the evidence that the fillament type links between the galaxies is in fact Dark Matter? a theoretical substance to explain the up until now unexplained things current theories dont/cant
