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!

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.
What is a dark matter microscope used for?
There's no such thing as a "dark matter microscope." The whole point of dark matter is that it doesn't interact with electromagnetic radiation... if it did, it wouldn't be dark matter.
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.
How strong is dark matter?
Dark matter's strength is proportional to it's mass. This means that more dark matter in one spot is stronger then a little bit of dark matter in that same spot.
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.
Is matter being transformed into space by black holes?
No, when the big bang happend dark matter and dark energy came. Dark matter expands space even as we speak.

What is a thing that's not made up of matter?
antimatter and dark matter
How many dark matter can scientists see?
By definition, "dark" (look up what that word means!) matter can not be seen.
Who came up with the theory of matter?
Neils Bohr came up with the kinetic Theory of Matter, also known as: The Molecuar Theory of Matter, and The Bohr Model.
Is dark matter dangerous?
No, it is invisible, however it got gravity. No one actually come up with a theory that explain what dark matter really do, so there is still a Noble Price waiting for people to come up with a explanation of dark matter.
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.
What's the dark matter in the universe?
Dark matter is matter of an unknown type. It is known to exist, due to its gravitational influence, but it is not known what it is made of. There is at least 5 times as much dark matter than "normal" matter.
What is the definision of matter?
Matter is anything that has mass and occupies space. Baryonic matter, matter that is made of electrons, protons, and neutrons, only makes up 4% of the universe. Dark Matter, we don't know the composition, makes up 23% The rest is dark matter 73%
What percentage of the universe is dark matter?
Roughly 70% of the Universe is dark energy. Dark matter makes up about 25%. The rest, everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the Universe. That is, with the knowledge and the proof that both dark energy and dark matter exist rather than inferences.
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 a material that takes up space called?
Dark matter
