In astrophysics self-interacting dark matter is a hypothetical form of dark matter consisting of particles with strong self-interactions. This type of dark matter was postulated to resolve a number of conflicts between observations and simulations on the galactic scale and smaller. Self-interacting dark matter has also been postulated as an explanation for the DAMA annual modulation signal.

Famous quotes containing the words dark and/or matter:

    A Scholar is a candle which the love & desire of men will light. Let it not lie in a dark box.
    Ralph Waldo Emerson (1803–1882)

    I am often mad, but I would hate to be nothing but mad: and I think I would lose what little value I may have as a writer if I were to refuse, as a matter of principle, to accept the warming rays of the sun, and to report them, whenever, and if ever, they happen to strike me.
    —E.B. (Elwyn Brooks)
