Cold dark matter. It can't be seen or detected by its radiation.
Some say that ranks it with Bigfoot and the Tooth Fairy!

Is a measure of the amount of matter in a given amount of space?
is a measure of the amount of matter in a given amount of space
The measure of how much matter is in a given space?
mass is the answer
When you use a formula to calculate the area of a triangle does it matter which base - height pair you use.?
The side you use as the base does not matter. What does matter is that the height is the perpendicular distance between this side and the other vertex. If there is a right angle in the triangle, then use the two sides next to it as the base and height. Otherwise a bit of trigonometry will be required to work out the height of the triangle if it is not given.
True or false the order of numbers in an ordered pair doesn't matter?
False
What is the amount of space that matter fills?
The answer would be Density.
Why do astronomers think there is dark matter in the universe?
That is because the dark matter attracts normal matter through its gravitation.
What subsystems make up the universe?
It is theorized that dark matter makes up 80 percent of the universe. Another theory is that 68 percent of the universe is dark energy, 27 percent is dark matter, and 5 percent is baryonic matter.
Why do astronomers theorize that most of the matter in galaxies and clusters of galaxies is dark matter?
most of the mass in a cluster of galaxies is invisible, which provides astronomers with the strongest evidence that the universe contains a great amount of DARK MATTER
Why do astronomers theorize that most of matter in galaxies and clusters of galaxies is dark matter?

99 percent of the known matter in the universe?
99 percent of the known matter in the universe is said to be in the plasma state, This is a state where matter consists of ionized gas which makes it visible.
What percent of matter in the universe is not in the form of plasma?
15%
How much of the universe is matter?
The real question is how much of the universe's matter is this dick.
What two elements comprise almost 100 percent of the matter in the universe?
Hydrogen and helium make up nearly 100 percent of the matter of the universe. Hydrogen comprises about 75 percent and helium makes up about 25 percent.
What kind of scientist studies the universe and the planets galaxies stars and other objects within it?
Astronomers and physicists.
What force do scientists such as Saul Perlmutter believe is counteracting gravity and allowing the universe to accelerate the rate of its expansion?
Dark energy is the term to refer to the force that is causing an expansion of the universe to accelerate. It is estimated that the universe is 68.3 percent dark energy, 26.8 percent dark matter, and 4.9 percent ordinary matter.
What exists as ninety nine percent of all matter that can be observed in the universe?
The correct answer is: Plasmas
Most of the visible universe if made of?
The universe is around 70% dark energy (a.k.a. empty space). The rest is mostly dark matter, with a few percent for ordinary matter. That is the current scientific model.
