What Is Dark Matter Made Of

Dark matter may be made of baryonic or non baryonic matter.

What is dark matter made of.

Although we don t know the exact masses of neutrinos we at least have evidence that they exist. Most of this baryonic dark matter is expected to exist in the form of gas in. 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. That s almost all of it.

Other than that dark energy is a mystery but an important one. 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. To hold the elements of the universe together dark matter must make up approximately 80 percent of the universe. That only leaves a small 5 for all the matter.

Two varieties of dark matter have been found to exist. Dark matter appears to be a form of matter made up of an entirely different class or classes of subatomic particle. Scientists named this stuff dark matter. Because scientists can t see dark matter directly they have found other ways to investigate it.

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 energy. One of the most promising is called a wimp. A weakly interacting massive particle.

More is unknown than is known we know how much there is and we know some of its properties. The rest is dark matter. But it seems that 27 of the universe or about one quarter is made up of the strange stuff. Just like dark energy we don t know a whole lot about dark matter.

Those particles might be massively heavy or wispily light. 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 makes up about 25. It may be filled with particles predicted by theory but that scientists have yet to observe.

The missing matter. Together dark energy and dark matter make up 95 of the universe. 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. Is dark matter made from supersymmetric particles.

Roughly 70 of the universe is made of dark energy.
