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:
“Slowly he entered dark and silence and lay there for so long that with what judgement remained he judged them to be final.”

“Were that enough, bone, blood, and sinew,
The twisted brain, the fair-formed loin,
Groping for matter under the dog’s plate,
Man should be cured of distemper.
For all there is to give I offer:
Crumbs, barn, and halter.”
—Dylan Thomas (1914–1953)
