Comment on If dark matter doesn't emit, absorb, or reflect light, what happens when light hits it?

  Yeah, it just doesn’t hit it.

  Gravity does work with dark matter tho, so we can’t really say “unaffected” because the dark matter would still bend the light due to gravity. I’m not sure if we can detect that bend, but I remember something relatively recently about how dark matter can interact via gravity, and I’m assuming bending light would have been the easiest way to test that.

    I guess we could, if only we knew where our dark matter is :)
