What is dark matter? Why should we care about it, and how are researchers attempting to find it?

My question from where to get 20% univers ?

[juskogovsek]

As I know, in the beginning of the universe was a battle between matter and antimatter, and matter won, because there was a little bit more matter then antimatter. Maybe dark matter is somekind of a quantum particle made when matter and antimatter anihilate each other?

How do you figure the 20% and measuring the 80% rest?

Does it exist?

Someone could ask who is Peter Pan and you could give an answer that fails to mention that Peter Pan is fiction.
