B The distribution of normal matter precisely determines gravity

    I am unable to find a paper on this only the abstract, but it seems to be saying that there is no Dark Matter?

    The tightness of this relation is difficult to understand in terms of dark matter as it's currently understood, the researchers said.

    It also challenges the current understanding of galaxy formation and evolution, in which many random processes such as galaxy mergers and interactions, inflows and outflows of gas, star formation and supernovas, occur at the same time.

    I think that there has been several papers like this one all proved to have systematic errors.

    Eh, I doubt that the tightness of the relation is all that difficult to understand, given that dark matter and normal matter are pretty strongly correlated.

    More importantly, there are some known physical systems, such as the Bullet Cluster, where the gravity most certainly is not correlated with the normal matter.
