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.
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.
Were is most of the dark matter in the milky way universe?
I dont know correctly but it may be most of the galaxy I think so! In reality we don't 'know' but our best understanding is; Ordinary matter: ~4.5 %, dark matter: 23%, dark energy: 72%. Reputedly 80% of this 23% dark matter is cold dark matter and 20% is hot dark matter. It has been said that "dark matter.... makes up more than 80% of the matter of the universe." but that is a common misunderstanding; But we MAY say; up to 96% of the mass-energy in the universe is 'dark'. We don't know what dark matter is, but in fact it only means it does not have an easily detectable 'electromagnetic cross section' so it could be electrons/ions plasma, which has a refractive index of 1.
Compare the amount of visible matter in the universe with the total amount of matter and energy?
4% Visible Matter (Atoms) 23% Dark Matter 73% Dark Energy
Where is the largest dark matter in the universe?
Dark matter is everywhere, there really is no place that has the most dark matter.

Why do astronomers theorize that there is dark energy in the universe?
There are several pieces of evidence for dark matter. For example: * Our galaxy, and many other galaxies, rotate way too fast for the amount of known matter. * Evidence from gravitational lensing.
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 ultimate matter in the universe?
Black or dark 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

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.
