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.

    Why look in the dark for light?

    “Money is good and a girl might be better,
    No matter what happens and who takes the fall,
    But a good strong cause”Mthe rope gave a jerk there,

    But he kicked before he died,
    He did it out of pride.
