    Bullet cluster.

    I don't know why people are so resistant to the concept of dark matter. "There are particles that interact via gravity and no other forces" is not that outlandish of a hypothesis, and it fits a whole bunch of observed phenomena.

      There have been papers explaining bullet cluster effects without invoking new particles.
