What Is Dark Matter Made Of
Is dark matter made from supersymmetric particles.
What is dark matter made of. Those particles might be massively heavy or wispily light. Scientists named this stuff dark matter. But it seems that 27 of the universe or about one quarter is made up of the strange stuff. Most of this baryonic dark matter is expected to exist in the form of gas in.
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. Two varieties of dark matter have been found to exist. Dark matter could be made of one kind of particle or many. One of the most promising is called a wimp.
What is dark energy. A weakly interacting massive particle. Dark matter makes up about 25. Although we don t know the exact masses of neutrinos we at least have evidence that they exist.
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. That s almost all of it. Dark matter may be made of baryonic or non baryonic matter.
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. Roughly 70 of the universe is made of dark energy. Dark matter may not be made up of the matter we are familiar with at all.
The missing matter. Dark matter appears to be a form of matter made up of an entirely different class or classes of subatomic particle. 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. Other than that dark energy is a mystery but an important one.
Because scientists can t see dark matter directly they have found other ways to investigate it. Just like dark energy we don t know a whole lot about dark matter. The rest is dark 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.
To hold the elements of the universe together dark matter must make up approximately 80 percent of the universe.
