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.

“In Tsegihi,
In the house made of dawn,
In the house made of the evening twilight,
In the house made of the dark cloud, ...
Oh, male divinity!
With your moccasins of dark cloud, come to us.”

“The Soul rules over matter. Matter may pass away like a mote in the sunbeam, may be absorbed into the immensity of God, as a mist is absorbed into the heat of the Sun—but the soul is the kingdom of God, the abode of love, of truth, of virtue.”
—Ralph Waldo Emerson (1803–1882)
