Dark Matter Facts. Dark matter makes up about 85 percent of the total matter in the universe, accounting for more than five times as much as all ordinary matter. Dark matter played an important role in the formation of galaxies and the evolution of the universe.
More than 80% of the universe is made of stuff we have never seen. These ghostly forms of energy and matter are only detectable by the effects they have on the stuff we can see. The invisible form of matter, called dark matter, makes up roughly 30% of the universe’s total mass. Its gravity drives […]
The rest is composed of dark matter and dark energy, which are invisible but dominate the structure and evolution of the universe. Dark matter makes up most of the mass of galaxies and galaxy clusters, and is responsible for the way galaxies are organized on grand scales.
Dark matter. Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter. Dark matter ...
Jun 1, 2018 · Dark matter should really be called transparent matter because, as with all transparent things, light just passes through it. Nevertheless, its nature is far from transparent. Physicists and ...
Aug 28, 2006 · Dark matter must be the basic building block of the largest structures in the universe: galaxies and clusters. Without dark matter, the universe would be a very different place, according to ...
Sep 8, 2020 · It will also perform 'tomography' of the dark matter structures by analysing the way dark matter helps to warp the images of more distant galaxies through a phenomenon known as weak gravitational lensing. Once its distribution is better known, the behaviour of the dark matter can be inferred and this should provide valuable clues as to its ...
