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
mass is the answer
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.
The answer would be Density.
False
That is because the dark matter attracts normal matter through its gravitation.
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.
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

15%
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.
The real question is how much of the universe's matter is this dick.
Astronomers and physicists.
The remaining 3 percent of the universe's composition primarily consists of dark energy, dark matter, and ordinary (baryonic) matter. Dark energy, which makes up about 68 percent, drives the universe's accelerated expansion. Dark matter, accounting for about 27 percent, exerts gravitational effects yet does not emit light, remaining invisible to current detection methods. Ordinary matter, including stars, planets, and galaxies, constitutes roughly 5 percent of the universe.
The correct answer is: Plasmas
Astronomers discover black holes in the universe by observing the effects they have on nearby objects, such as stars and gas. They use telescopes to detect X-rays and other forms of radiation emitted by black holes, as well as studying the gravitational influence they have on surrounding matter.
Yes it is very true
