What does dark matter have to do the critical of the universe?

Dark matter is actually Melanin. Melanin is the pigment that gives us color. Black people have 12 Melanin centers in their brain, while white people only have 2. Melanin allows us to covert the Sun's light waves into Sound waves, which gives the universe its shape and us the ability to shape the universe through the law of vibration.

Dark matter is crucial for understanding the critical density of the universe. The presence of dark matter significantly increases the total mass and therefore the gravitational pull of the universe, which affects its overall structure and expansion. Without accounting for dark matter, the observed gravitational effects would not align with the predicted critical density required for a flat universe.

Is the universe matter?
The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.
The amount of dark matter in the universe important?
Yes it is important because on basis of dark matter amount our universe will expand.
Why can't the so called dark matter be directly observed?
We know that dark matter exists because it got gravity, though it is invisible. It hold galaxy and Universes. There is a theory there many other parallel universe outside our universe and dark matter holds those universe up and some scientists says that dark matter are just mass of the matter of the parallel universe. It sounds crazy but that is the Law of Physics. However there is not exact explanation of what dark matter really is, so there are still Noble Prices for those who can come up with a reasonable explanation.
Is the mysterious dark matter the fastest-moving material in the universe?
no
How does dark matter affect us?
"Dark Matter" is currently only a mathematical concept, a "fudge factor" thrown into some calculations to make the numbers work out. We have no idea if "dark matter" really exists, how it would affect the universe, or how it might be detected or manipulated. It's all guesswork, and all the scientists have conflicting guesses. For myself, I suspect that there are some fundamental things that our theories do not yet understand, and that in the future, we'll discover that "dark matter" will prove to be nothing at all.
Where is the largest dark matter in the universe?
Dark matter is everywhere, there really is no place that has the most dark matter.

What is the ultimate matter in the universe?
Black or dark matter
Is there a lot of dark matter in the universe?
Depends what you mean by "a lot." The gravitational effect of dark matter -- whatever the stuff happens to be -- is about six times greater than that of all the visible matter in our Universe.
What is the percentage of dark matter in your universe?
In my Universe, about 23% of its energy is found in dark matter -- about four to five times more than in matter we happen to understand. I don't know the percentage in your Universe.

Is dark energy and dark matter killing the universe?
No. What is killing the Universe is the Second Law of Thermodynamics.
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.
How dense is dark matter?
This can be answered in two steps: 1) What is the average density of all gravitational matter in the Universe? It has surprised astrophysicists that this density is extremely close to the "critical" density; above which our Universe eventually collapses in itself, and below which our Universe expands forever. This critical density is about 5 x 10^-30 grams per cubic centimeter. 2) How much of the mass of the Universe is NOT dark matter? What shocked astrophysicists even more was determining that the average density of all luminous matter was only about 20% of the critical density. Thus, about 80% of the measured density of our Universe can be accounted for via stuff that gives off light. The ratio of hydrogen to helium to deuterium in our Universe puts an upper limit on the density of baryonic matter in our Universe. This calculation also shows that the density of baryonic matter can not be more than about 20% of the critical density. These two, completely independent calculations of the amount of luminous and of baryonic matter -- the stuff we understand -- in our Universe have left scientists with little choice but to conclude that 80% of the gravitational mass in our Universe is composed of something we don't understand. And that's why we call it "dark" matter. Since the Universe has a density of 5 x 10^-30 grams per cc, and only 80% of that is dark matter, then the latter's average density is about 4 x 10^-30 grams per cc.
Does dark matter/energy responsible for the expansion of the universe?
Yes. Dark energy is responsible for the expansion of the universe.
Which is thought to be more prevalent in the universe dark matter or dark energy?
Dark energy. The current estimates for the distribution of mass/energy in the Universe are approximately: 68% dark energy 27% dark matter 5% baryonic (i.e. "normal") matter
