NO we can not get the samples of dark matter as it is the type of matter in astronomy and cosmology that can not be even seen with telescopes.

Is dark matter related to antimatter in any way?
No, dark matter is entirely different from antimatter. For one, we know a lot about antimatter and have been able to do experiments with it and actually utilize it in some nuclear reactions. Dark matter is a theory to help understand why the universe does not behaive the way we believed it should. Galaxies are showing that they do not have enough mass to have the gravitational effects that they do, so there must be matter somewhere, this is labeled as dark matter.
Is dark matter Solid liquid or gas?
We do not know as we have not found any dark matter to examine. The only way we detect it and know it exists is due to its gravitational attraction of the ordinary matter we can see. One speculation when neutrinos were discovered to have tiny nonzero masses was that dark matter might be neutrinos. Another speculation is that dark matter is only ordinary matter, but its in another separate universe in a shared higher dimensional spacetime. Nobody knows.
Why can't sound travel trough dark matter as we say it is present everywhere?
Not much is currently known about dark matter, but it obviously doesn't react in the same way as normal matter does.
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.
Does dark matter or dark energy exist?
No, darkness does not exist. It is just the absence of light. Actually, I would argue that darkness DOES exist, although not in any material form, just as light exists, but not in any tangible way. If you turn out the light in a room, then you are surrounded in darkness; it is actually real for you, as in, something you must deal with in a practical way (you need to see to live) and so, does exist. As opposed to an imaginary friend, say, which does not have any physical effect on you, in the real world, as the absence of light does. No, darkness does not exist. It is the absence of light. Darkness can`t be measured Light can be measured and broken down. The Law of Physics.
Is it true dark matter cannot be seen?
Yes this is true. We have recently discovered dark matter exists with the help of the Hadron particle collider, but can not see dark matter. (not yet any way)
Can dark matter be used as an everyday energy souce?
As of yet, way too little is known about dark matter to speculate about any practical uses.
Is dark or anti-matter been found or saved with the use of the collider?
"Anti-matter" . . . yes, routinely. "Dark matter" . . . no way to know. The reason it's called "dark" is that it can't be seen or detected in any way currently available to us; its existence is a hypothesis that's presently untestable.
What are some possible forms the dark matter in the halo of the Milky Way might be in?
We don't yet know enough about dark matter - or even if it really exists - to be able to speculate on what "form", if any, it might take. You have to remember that "dark matter" is entirely theoretical, based on the supposed fact that the Milky Way doesn't have enough mass to keep it together, and that therefore there must be additional matter that we can't see - "dark" matter - to keep it all together. We've never detected any, nor do we know if we CAN detect any.

How are populations and samples symbolized?
Any way that you want to.

Does dark matter possess any mass and energy?
Yes, dark matter has a lot of mass. It makes up about 20% of the universe (much more than regular matter). Since it has mass, it also has energy. In fact, dark matter's mass is the main reason we even know it exists. Astrophysicists can observe its gravitational effects, though it is extremely hard to detect in any other way.
Did Heath Ledger really cut his mouth?
No, that was makeup for the movie. Doesn't matter any way he is dead. ^Does it matter if he is dead or not?
Is dark matter actually matter?
"Dark matter" interacts with baryonic matter -- ie, the stuff we understand -- via gravity but not in any other significant way. Not via the electromagnetic force, nor via the strong force, possibly not even via the weak force. What this stuff happens to be is still being debated. Dark matter, however, can NOT be simply energy in our cosmos. If it were, it would push space apart -- which is what dark energy is doing. Dark matter, on the other hand, is doing the exact opposite -- it is pulling space (and the matter within it) into it. Thus, dark matter is SOME kind of matter (or mass, which is the same thing) which, at present, we don't fully understand yet.

Does anyone no if you have proof dark matter exists?
The clear answer is, we don't. We cannot detect the hypothetical "dark matter", and the only reason we are talking about "dark matter" is that we cannot actually see enough mass in the Milky Way galaxy to account for the gravity that we know must be there - because the Milky Way would fly apart with only the mass that we can see. The "dark matter" may be in the form of invisibly-dim brown dwarf stars, or black holes, or "something else". Dark matter is the "something else". Everything you read about dark matter is a guess.
