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.
It is estimated that the matter in the Universe is divided up as follows: 4% "normal" matter (this is the part we know best), 23% dark matter, 73% dark energy. We don't know much about dark matter, but it is clear that it does exist (it manifests itself by its gravitational attraction, so it can't hide completely). We know even less about dark energy.
I presume your question is "WHERE is most of the dark matter in the Milky Way Galaxy."
I change the last word simply because the Milky Way is a galaxy, not a Universe.
Dark matter, being a "something" that interacts with other "somethings" only via gravity, congregates where other "somethings" with gravity congregate. In any galaxy, that would be in the central core. The evidence is still being examined; however, it seems that, everywhere in our Universe, there is about five parts dark matter for every one part baryonic matter -- the latter being "the stuff we actually understand."
There is about 5 times more dark matter than "normal" matter (the matter we are familiar with). The percentages are estimated as follows: the Universe is made up of 4% normal (a.k.a. baryonic) matter, 23% dark matter, and 73% dark energy.
The dark matter may be invisible, but it can still be noticed by its gravitational effects. For example, galaxies rotate way too fast for the amount of known matter; therefore, there must be additional mass holding them together.
i don't know',so haha
Plasma is the most common type of matter in the universe
The Universe is expanding. That is, it is getting bigger.The Universe is expanding. That is, it is getting bigger.The Universe is expanding. That is, it is getting bigger.The Universe is expanding. That is, it is getting bigger.
I am researching that question too, All I know is: · dark matter is hypothetical matter that is undetectable by its emitted radiation · presence can be found from gravitational effects on visible matter · Dark matter is believed to play a central role in structure formation1 and galaxy evolution1 · most of the matter in the entire Universe is invisible · invisible stuff is called dark matter · called "dark" because it does not emit any light · cannot be seen directly Have fun!
"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.
The simplest answer is: Everything does. One possible definition of 'Universe' is: All of time and space and everything in them.
Dark matter is everywhere, there really is no place that has the most dark matter.
The most common type of energy/mass in the Universe is in the form of dark energy, followed by dark matter. Only about 4% of the Universe is in the form of "normal" (baryonic) matter. If it is specifically to this matter you refer: the most common state of matter is plasma, found in stars.

If we are talking about normal matter, as opposed to the dark matter, that would be plasma.
Atoms make up most matter around us. In the Universe in general, it seems that atoms make up about 4% of the mass of the Universe. The remainder of the Universe mass is dark matter and dark energy - both of unknown composition.
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.
Current theory states that it's "dark energy".
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

Plasma. That's ignoring "dark matter", because we don't yet know what that is.
Dark energy is believed to make up about 73% of the mass of the Universe; dar matter about 23%; and normal matter - the kind we know most about - about 4%. In the case of normal matter, most of it is still in the form of hydrogen.
The Milky Way contains somewhere around 200 billion stars. These stars account for about 20% of the visible mass of the galaxy, the other 80% being interstellar gas. However, most of the matter in our galaxy is of a form we have not yet identified, and we call it "dark matter." We don't know what it is, but we can measure its effect on the rotation rate of the stars, and we can calculate the distribution of the dark matter.
