> Read the article this thread is about. It is one brand new paper. I am skeptical. Rotation curves are perfectly flat out to whatever arbitrary distance that they happen to be able to measure? I am very skeptical. > "particle DM can't fully explain the Bullet Cluster either." According to one scientist, who happens to be the same scientist claiming that particle DM cannot explain rotation curves. I will not check every claim, but the bullet cluster collision speed "problem" is readily explained in the reference in the wikipedia article: https://arxiv.org/abs/1410.7438 The broader point is…
