 finding it without success

I might be wrong (it has been known ;) ! ) but I think it has been found, and mapped, in distant galaxies (and/or clusters) by gravitational lensing.

What has not been found is what it is made of, dark chocolate, black cheese or something else !

I think Jim was being mischievous* by saying we did not know if dark matter was present in and responsible for our galaxy and its spiral arms. There may be another reason for the anomalous orbital velocity of the stars in the disc/arms.

Edit : * he said it with a twinkle in his eye I thought, but let us jest not, it is good to hear a scientist with an open mind, you dont find many of those !!
