Dark Matter

Dark matter is a kind of matter, which only shows itself by its gravitation, it doesn't emit observable electromagnetic radiation. The rotation of galaxies can't be explained by the visible, baryonic matter alone. It seems that there is five time as many dark matter than there is shining matter (atoms always shine, but not always in visible light). We don't know of what dark matter is made. Although there are some candidates, like neutrinos or even new particles, all these are disputable and no proofs have been made so far. The state of knowledge at dark energy is even worse.
