What Is Dark Matter Made Of

Dark matter makes up about 25.

What is dark matter made of.

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. Although we don t know the exact masses of neutrinos we at least have evidence that they exist. One of the most promising is called a wimp. What is dark energy.

More is unknown than is known we know how much there is and we know some of its properties. It may be filled with particles predicted by theory but that scientists have yet to observe. The missing matter. To hold the elements of the universe together dark matter must make up approximately 80 percent of the universe.

The rest is dark matter. That s almost all of it. The matter that makes up dark matter could different. Scientists named this stuff dark matter.

Is dark matter made from supersymmetric particles. Dark matter may be made of baryonic or non baryonic matter. 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. 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.

But it seems that 27 of the universe or about one quarter is made up of the strange stuff. Because scientists can t see dark matter directly they have found other ways to investigate it. Most of this baryonic dark matter is expected to exist in the form of gas in. The rest everything on earth everything ever observed with all of our instruments all normal matter adds up to less than 5.

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. Other than that dark energy is a mystery but an important one. Roughly 70 of the universe is made of dark energy.

Those particles might be massively heavy or wispily light. A weakly interacting massive particle. Just like dark energy we don t know a whole lot about dark matter. Dark matter could be made of one kind of particle or many.

That only leaves a small 5 for all the matter.
