It provides strong evidence of matter that we cannot detect. Milgrom's reply is worth a read: https://web.archive.org/web/20160721044735/http://www.astro.umd.ed

Thus... dark matter?

  Isn't dark matter something like a shadow DOM.. It's there but also not there? Edit! Wow really feeling the love on this comment What I mean is dark matter is different from matter we just can't detect, it's matter that should be there but we can't seem to find it

    It's pretty simple: Dark Matter can't be seen or felt. It probably just travels through regular matter without "colliding", muchlike neutrinos. It only interacts with other matter through gravity. Now, we can detect gravity, but only for fairly big and stationary objects. If DM is tiny particles travelling fast, we can only detect aggregate effects on galaxy level.

      Yes just like we can't detect the shadow DOM from the DOM but it's really there you know? I feel like my thinking is too orthogonal any more. There's a difference between matter that's there which we can't detect as opposed to matter which isn't there which we can oh geez

        If you're making sense, I can't detect it :)

        Ever feel like you're too salty for your shirt? Can you appreciate the juktaposition of shadow DOM and dark matter or nah? I just post these comments so I can whittle my score back to zero and give you something to think about while you churn out features.

        Maybe it is similar in that the shadow DOM predicts the state of the actual DOM. In this interpretation dark matter predicts the shape of our universe. It might just be how one should go about simulating a universe..!

  No. Because dark matter is understood mostly to be less interacting matter. Don't think it's a ball of dark stuff, think something you couldn't even see Whereas he's proposing regular (dark as in color) matter

    > Whereas he's proposing regular (dark as in color) matter Wouldn't that kind of matter be easily detectable because it would block EM radiation, including visible light?

      Yes. "Dark" is misleading, it should be "sparsely-interacting" or something. Well, MACHOs would have been dark in the traditional sense as well. Generally, "we would have seen it" excludes a lot of dark matter candidates, thats what actually makes it "dark"

    That's my understanding as well.
