What Is Dark Matter Made Of

Although we don t know the exact masses of neutrinos we at least have evidence that they exist.

What is dark matter made of.

The rest is dark matter. Dark matter appears to be a form of matter made up of an entirely different class or classes of subatomic particle. More is unknown than is known we know how much there is and we know some of its properties. 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 may be made of baryonic or non baryonic matter. The rest everything on earth everything ever observed with all of our instruments all normal matter adds up to less than 5. A weakly interacting massive particle. Dark matter may not be made up of the matter we are familiar with at all.

The missing matter. What is dark energy. Dark matter could be made of one kind of particle or many. That only leaves a small 5 for all the matter.

We think it only interacts with other matter and itself via gravity but dark matter could turn out to have interactions with any force of nature known or unknown. Is dark matter made from supersymmetric particles. But there is a long list of hypothetical particles that might well exist and if so could have survived from the big bang in sufficient numbers. Dark matter makes up about 25.

Together dark energy and dark matter make up 95 of the universe. Those particles might be massively heavy or wispily light. 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 matter that makes up dark matter could different.

That s almost all of it. 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.

Just like dark energy we don t know a whole lot about dark matter. It may be filled with particles predicted by theory but that scientists have yet to observe. Most of this baryonic dark matter is expected to exist in the form of gas in. Other than that dark energy is a mystery but an important one.

Roughly 70 of the universe is made of dark energy.
