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:
“While I wrought out these fitful Danaan rhymes,
My heart would brim with dreams about the times
When we bent down above the fading coals

Of passionate men, like bats in the dead trees....”
—William Butler Yeats (1865–1939)
“New York is a meeting place for every race in the world, but the Chinese, Armenians, Russians, and Germans remain foreigners. So does everyone except the blacks. There is no doubt but that the blacks exercise great influence in North America, and, no matter what anyone says, they are the most delicate, spiritual element in that world.”
—Federico García Lorca (1898–1936)
