Evidence for Dark Matter Beyond Rotation and Clusters

[Forestman]

Besides keeping the whole of galaxies rotating at the same rate, and holding galactic clusters together, what are the other forms of evidence for dark matter?

Look up the "bullet cluster". It's almost the smoking gun for dark matter.

Thanks, I will.
