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.
    Robert Frost (1874–1963)
