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