The invisible form of matter, called dark matter, makes up roughly 30% of the universe’s total mass.

Although astronomers cannot see dark matter, they can detect its influence by observing how its gravity bends and ... In astronomy, dark matter is a hypothetical form of matter that appears not to interact with light or the electromagnetic field. Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be seen. A dark answer. Dark matter existed as a concept, first proposed by astronomers like Jan Oort in 1932 and Fritz Zwicky in 1933, who also noticed discrepancies in how much mass astronomers could see ...Dark energy and dark matter describe proposed solutions to as yet unresolved gravitational phenomena. So far as we know, the two are distinct. Dark …Dark matter is dark: It emits no light and cannot be seen directly, so it cannot be stars or planets.

Dark matter is a hypothetical invisible mass thought to be responsible for adding gravity to galaxies and other bodies. Since the amount of visible material in galaxies can't account for their shapes, distributions, and movements, astrophysicists argue there must be a form of mass yet to be discovered. This mass doesn't appear to affect normal ...

Dark Matter. Visible stars are not the only matter in space; in fact, the majority of matter in the universe is known as dark matter due to the fact that it cannot be directly observed. Instead, astronomers and cosmologists infer the existence of dark matter due to its gravitational influence on visible matter. To find dark matter particles, the Cryogenic Dark Matter Search (CDMS) team buried an array of germanium cells deep beneath the ground in Soudan, Minnesota. If dark matter particles exist, they should pass through solid earth and strike the nuclei of the germanium atoms, which will recoil and produce tiny amounts of heat and energy.

Dark matter is effectively invisible because it is "weakly interacting" with light.

Dark matter comes in two varieties: baryonic, which is about 5 percent of ... Dark matter is material that cannot be seen directly. We know that dark matter exists because of the effect it has on objects that we can observe directly. Scientists study dark matter by looking at the effects it has on visible objects. Scientists believe that dark matter may account for the unexplained motions of stars within galaxies. In this public lecture, Fermilab physicist Dan Bauer explains what scientists know about dark matter, the mysterious, invisible stuff that accounts for most of the matter in the universe. After presenting evidence for the existence of dark matter, he describes some of the physics experiments that scientists build and operate to look for signals from …It has never been detected, only speculated.

The dark stars would be composed mostly of normal matter, like modern stars, but a high concentration of neutralino dark matter present within them would generate heat via annihilation reactions between the dark-matter particles. This heat would prevent such stars from collapsing into the relatively compact and dense sizes of modern stars and ...

Cold Dark Matter. The universe is made up of at least two kinds of matter. Primarily, there's the material we can detect, which astronomers call "baryonic" matter.
