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.

“It’s the old captain’s dark fate
Who failed to find or force a strait
In its two-thousand-mile coast;
And his crew left him where he failed,
And nothing came of all he sailed.”

“A living man is blind and drinks his drop.
What matter if the ditches are impure?
What matter if I live it all once more?”
