What Is Dark Matter Made Out Of

That only leaves a small 5 for all the matter.

What is dark matter made out of.

That s almost all of it. The rest everything on earth everything ever observed with all of our instruments all normal matter adds up to less than 5. Just like dark energy we don t know a whole lot about dark matter. It can t be directly observed with any of the existing tools of astronomers.

Some astronomers speculate that dark matter may be made up of copious numbers of black holes. It may be filled with particles predicted by theory but that scientists have yet to observe. Dark matter may be made of baryonic or non baryonic matter. Dark matter doesn t emit light.

To hold the elements of the universe together dark matter must make up approximately 80 percent of the universe. Dark matter may not be made up of the matter we are familiar with at all. Two varieties of dark matter have been found to exist. Scientists named this stuff dark matter.

The matter that makes up dark matter could different. 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. 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.

Roughly 70 of the universe is made of dark energy. 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. The rest is dark matter.

More is unknown than is known we know how much there is and we know some of its properties. Together dark energy and dark matter make up 95 of the universe. One of the most promising is called a wimp. Yet astrophysicists believe it and dark energy make up most of the mass of the cosmos.

Dark matter appears to be a form of matter made up of an entirely different class or classes of subatomic particle. Because scientists can t see dark matter directly they have found other ways to investigate it. What is dark energy. These are thought to power distant k type quasars.

A weakly interacting massive particle.
