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.
False
The answer would be Density.
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 comprise almost 98% of the matter in the universe. They were created during the Big Bang and are the most abundant elements in the universe.
The real question is how much of the universe's matter is this dick.
Astronomers and physicists.
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
If they are astronomers, they classify everything as 'interesting'. I think the answer may be something like "matter or energy". In fact, according to Relativity Theory, mass (of matter) and energy are in many ways equivalent. "Mass-energy" is a term often used to refer to this fact. Pretty well everything in the Universe is matter or energy,
