Dark matter wasn't "discovered" by any one person or group. In fact it is still hypothetical and there is no solid proof for its existence. Various astronomers inferred the existence of dark matter from what they observed about galaxies and galaxy clusters. It is still very much a mystery and the subject of some serious research.

Dark matter has yet to be discovered or its properties fully understood

When was dark matter discovered?

You will find it interesting that in fact dark matter has not yet been discovered. We are trying hard to observe evidence of dark matter, but it is not revealing itself at this time. It is theorized to be there, based on what we know about how the galaxies are moving and how they are interacting with one another. Dark matter is a theory waiting for verification.

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)

What is the evidence for the existence of dark matter in the universe?

The evidence for the existence of dark matter in the universe includes the extra mass of Galactic clusters discovered by Fritz Zwicky, and the spinning galaxies which rotate at the same speed as discovered by Vera Rubin.

What is the difference between dark matter and antimatter?

We know that anti-matter exists; we can make it, although in VERY tiny quantities. "Dark matter", on the other hand, is still only a theory, and we've never discovered any - or at least, not that we can be certain of.

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.

Who found dark matter?

No one has discovered dark matter. Dark matter is a concept to explain the rotation of galaxies. We simply do not know what it is and where it is. When we looked at nearby spiral galaxies astronomers could not explain how individual stars could be moving so fast. If you add all the mass of the material we can see or infer the gravity should not be able to hold the stars in orbit. They should be streaming off. Dark matter was invented to explain this. The theory suggest that 60 to 90% of the matter in the galaxy needs to this strange dark matter.

Can there be a possibility of anti-dark-matter?

Too little is known about dark matter to speculcate on this.

Where is the largest dark matter in the universe?

Dark matter is everywhere, there really is no place that has the most dark matter.

Who's the scientist who discovered matter?

Aristotle discovered matter

How fast does dark matter move?

At present we don't know what dark matter IS, let alone how fast it moves. In discussing hypotheses about dark matter, scientists have developed the terms "cold" dark matter, "warm" dark matter, and "hot" dark matter; with the "hot" hypotheses viewing dark matter as moving faster than it would if it were "cold."

Is dark matter a subatomic particle?

Dark matter is an unknowm form of matter.

Who discovered the dark line spectrum?

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.

Who is the scientist who discovered matter?

How do we know the gravitational effects hypothetically attributed to dark matter are not in fact caused by black holes?

That's easy! We don't. So far, no sign of the proposed "dark matter" has been discovered, nor have the properties of "dark matter" been firmly defined. The concept is still evolving, and will do doubt be extensively modified in the coming years.

What percentage of the universe is speculated to be composed of dark matter and dark energy?

What is the scientific term for the opposite of dark matter?

The opposite of dark matter is visible matter.

Does dark matter or dark energy exist?

Dark matter does. Dark matter is a strange thing that can only be detected by watching how light travels to us from distant stars. Light will navigate around dark matter to reach its destination. Dark matter is also how galaxies stay stable.

Why is it unlikely that dark matter is composed mostly of stars?

Stars emit light. By definition, "dark" matter does not. Thus, dark matter can not be stars.

What compose the universe?

1% - Matter and Anti-matter 23% - Dark matter 76% - Dark energy

What is dark matter state?

I presume the question you are asking is, "In what state of matter is 'dark matter'?" The answer is simple: we don't know, because we don't know what dark matter consists of. Dark matter might be closest to a gas, but it just as likely to be closest to a solid. Until we learn what dark matter IS, we can't get a good idea on what state of matter it most closely resembles.

What percentage of dark matter the universe have?

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.
