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:
“Alvina felt herself swept ... into a dusky region where men had dark faces and translucent yellow eyes, where all speech was foreign, and life was not her life. It was as if she had fallen from her own world on to another, darker star, where meanings were all changed.”
—D.H. (David Herbert)
“We only seem to learn from Life that Life doesn’t matter so much as it seemed to do—it’s not so burningly important, after all, what happens. We crawl, like blinking sea-creatures, out of the Ocean onto a spur of rock, we creep over the promontory bewildered and dazzled and hurting ourselves, then we drop in the ocean on the other side: and the little transit doesn’t matter so much.”
—D.H. (David Herbert)
