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:
“—the dark ajar, the rocks breaking with light,
and undisturbed, unbreathing flame,
colorless, sparkless, freely fed on straw,
and, lulled within, a family with pets,
—and looked and looked our infant sight away.”
—Elizabeth Bishop (1911–1979)
“No matter what life you lead
the virgin is a lovely number:
cheeks as fragile as cigarette paper,
arms and legs made of Limoges,
lips like Vin Du Rhône....”
—Anne Sexton (1928–1974)
