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.
What is dark matter made of.
Because scientists can t see dark matter directly they have found other ways to investigate it.
Scientists named this stuff dark matter.
That s almost all of it.
Dark matter could be made of one kind of particle or many.
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.
The rest everything on earth everything ever observed with all of our instruments all normal matter adds up to less than 5.
Dark matter may be made of baryonic or non baryonic matter.
Dark matter makes up about 25.
The rest is dark matter.
The missing matter.
Most of this baryonic dark matter is expected to exist in the form of gas in.
To hold the elements of the universe together dark matter must make up approximately 80 percent of the universe.
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.
Those particles might be massively heavy or wispily light.
More is unknown than is known we know how much there is and we know some of its properties.
Other than that dark energy is a mystery but an important one.
That only leaves a small 5 for all the matter.
What is dark energy.
Just like dark energy we don t know a whole lot about dark matter.
It may be filled with particles predicted by theory but that scientists have yet to observe.
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.
A weakly interacting massive particle.
Dark matter may not be made up of the matter we are familiar with at all.
Roughly 70 of the universe is made of dark energy.
Together dark energy and dark matter make up 95 of the universe.
Is dark matter made from supersymmetric particles.
The matter that makes up dark matter could different.
