(It does it by proposing a new vector field and scalar field that duplicate the effects of Cold Dark Matter in the early universe This doesn&#x27;t contradict what I said. These models are not simply removing DM, I said people have tried with modified gravity…</p><p><a href="https://hackerpaper.kaipfister.de/p/2007.00555/">Paper and discussion history</a>.
