What Is Dark Matter Made Of

That s almost all of it.

What is dark matter made of.

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. The matter that makes up dark matter could different. It may be filled with particles predicted by theory but that scientists have yet to observe. 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. Scientists named this stuff dark matter. 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 could be made of one kind of particle or many.

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. Because scientists can t see dark matter directly they have found other ways to investigate it. 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 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. That only leaves a small 5 for all the matter. More is unknown than is known we know how much there is and we know some of its properties. The missing matter.

Although we don t know the exact masses of neutrinos we at least have evidence that they exist. Dark matter may not be made up of the matter we are familiar with at all. Is dark matter made from supersymmetric particles. But it seems that 27 of the universe or about one quarter is made up of the strange stuff.

Together dark energy and dark matter make up 95 of the universe. Two varieties of dark matter have been found to exist. One of the most promising is called a wimp. Roughly 70 of the universe is made of dark energy.

Dark matter may be made of baryonic or non baryonic matter. Other than that dark energy is a mystery but an important one. Those particles might be massively heavy or wispily light. Dark matter makes up about 25.

To hold the elements of the universe together dark matter must make up approximately 80 percent of the universe.
