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:
“This, it will be remembered, was the scene of Mrs. Rowlandson’s capture, and of other events in the Indian wars, but from this July afternoon, and under that mild exterior, those times seemed as remote as the irruption of the Goths. They were the dark age of New England.”
—Henry David Thoreau (1817–1862)
“The lies fall like flaxen threads from the skies
All over America, and the fact that some of them are true of course
Doesn’t so much not matter as serve to justify
The whole mad organizing force under the billows of correct delight.”
—John Ashbery (b. 1927)
