Scientists look at that gas and measure how much there is between galaxies in clusters.
What does dark matter look like.
While things like human beings the earth the sun and everything that emits or absorbs light in.
Dark matter appears to be spread across the cosmos in a network like pattern with galaxy clusters forming at the nodes where fibers intersect.
The invisible matter that we can t detect is called dark matter the swiss astronomer fritz zwicky first used the term dark matter in the 1930s.
By doing this they discovered that there must be five times more material in the clusters than we can detect.
While this work does unfortunately throw cold water on what looked like what might have been the first evidence for the microscopic nature of dark matter it does open up a whole new approach.
So what does dark matter look like.
Dark matter has long baffled the scientific community despite making up an estimated 85 percent of all the matter in the universe.
Dark matter the scientists believe coexists with normal matter but they still don t know what it is.
Even though dark matter comprises 85 per cent of all matter in the universe it does not interact with light and can only be seen through the gravitational influence it has on light and other matter.
Scientists have been searching for dark matter an unknown and invisible substance thought to make up the vast majority of matter in the universe for nearly a century.
The reason for this.
It forms a central part of our most advanced theories about the universe itself and is therefore critical to our understanding of well pretty much everything.
Dark matter is one of the most mysterious and yet most ubiquitous substances in the universe.
