What Is Dark Matter Made Out Of

The rest everything on earth everything ever observed with all of our instruments all normal matter adds up to less than 5.

What is dark matter made out of.

Two varieties of dark matter have been found to exist. One of the most promising is called a wimp. It may be filled with particles predicted by theory but that scientists have yet to observe. But it seems that 27 of the universe or about one quarter is made up of the strange stuff.

Scientists named this stuff dark matter. Roughly 70 of the universe is made of dark energy. These are thought to power distant k type quasars. That only leaves a small 5 for all the matter.

Yet astrophysicists believe it and dark energy make up most of the mass of the cosmos. More is unknown than is known we know how much there is and we know some of its properties. Dark matter may be made of baryonic or non baryonic matter. Other than that dark energy is a mystery but an important one.

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. Because scientists can t see dark matter directly they have found other ways to investigate it. 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. Just like dark energy we don t know a whole lot about dark matter.

Some astronomers speculate that dark matter may be made up of copious numbers of black holes. That s almost all of it. A weakly interacting massive particle. The rest is dark matter.

Together dark energy and dark matter make up 95 of the universe. If the dark matter is made mostly of machos then it is likely that baryonic matter does make up most of the mass of the universe. Most of this baryonic dark matter is expected to exist in the form of gas in. What is dark energy.

Dark matter makes up about 25. 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. 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.
