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.

“Better to die, or not to have been born,
than hear that plaining, piteous convict wail
about these beautiful dark eyebrowed women.
It’s soldiers who sing these days. O Lord God.”

And better friends I’ll not be knowing,
Yet there isn’t a train I wouldn’t take,
No matter where it’s going.”
