What Is Dark Matter Made Out Of

Just like dark energy we don t know a whole lot about dark matter.

What is dark matter made out of.

Roughly 70 of the universe is made of dark energy. Dark matter may not be made up of the matter we are familiar with at all. Dark matter appears to be a form of matter made up of an entirely different class or classes of subatomic particle. But it seems that 27 of the universe or about one quarter is made up of the strange stuff.

Yet astrophysicists believe it and dark energy make up most of the mass of the cosmos. A weakly interacting massive particle. That only leaves a small 5 for all the matter. The matter that makes up dark matter could different.

The rest is dark matter. One of the most promising is called a wimp. Most of this baryonic dark matter is expected to exist in the form of gas in. Together dark energy and dark matter make up 95 of the universe.

It can t be directly observed with any of the existing tools of astronomers. The first variety is about 4 5 percent of the universe and is made of the familiar baryons i e protons neutrons and atomic nuclei which also make up the luminous stars and galaxies. The rest everything on earth everything ever observed with all of our instruments all normal matter adds up to less than 5. Scientists named this stuff dark matter.

Dark matter makes up about 25. Dark matter may be made of baryonic or non baryonic matter. What is dark energy. Because scientists can t see dark matter directly they have found other ways to investigate it.

Two varieties of dark matter have been found to exist. To hold the elements of the universe together dark matter must make up approximately 80 percent of the universe. That s almost all of it. More is unknown than is known we know how much there is and we know some of its properties.

These are thought to power distant k type quasars. It may be filled with particles predicted by theory but that scientists have yet to observe. Other than that dark energy is a mystery but an important one. The rest of the universe appears to be made of a mysterious invisible substance called dark matter 25 percent and a force that repels gravity known as dark energy 70 percent.

Dark matter is a form of matter thought to account for approximately 85 of the matter in the universe and about a quarter of its total mass energy density or about 2 241 10 27 kg m 3 its presence is implied in a variety of astrophysical observations including gravitational effects that cannot be explained by accepted theories of gravity unless more matter is present than can be seen.
