What Is Dark Matter Made Of

Dark matter may not be made up of the matter we are familiar with at all.

What is dark matter made of.

One of the most promising is called a wimp. Dark matter appears to be a form of matter made up of an entirely different class or classes of subatomic particle. Dark matter makes up about 25. Roughly 70 of the universe is made of dark energy.

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. 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 missing matter.

Dark matter could be made of one kind of particle or many. 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. It may be filled with particles predicted by theory but that scientists have yet to observe. That s almost all of it.

The matter that makes up dark matter could different. A weakly interacting massive particle. 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.

Other than that dark energy is a mystery but an important one. 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. Scientists named this stuff dark matter. Together dark energy and dark matter make up 95 of the universe.

To hold the elements of the universe together dark matter must make up approximately 80 percent of the universe. Is dark matter made from supersymmetric particles. More is unknown than is known we know how much there is and we know some of its properties. Those particles might be massively heavy or wispily light.

Two varieties of dark matter have been found to exist. That only leaves a small 5 for all the matter. The rest is dark matter. Just like dark energy we don t know a whole lot about dark matter.

But it seems that 27 of the universe or about one quarter is made up of the strange stuff.
