II. Relating the External Field Effect in Galaxy Rotation Curves to the Large-Scale Structure of the Universe — mentioned by atombenderhttps://news.ycombinator.com/item?id=32171928urn:hackerpapers:mention:2109.04745:32171928Wed, 20 Jul 2022 20:35:52 GMT<p>I don&#x27;t know what that video is describing, relative to EFE. The paper [1] abstract describes EFE and their findings this way: Theories of modified gravity generically violate the strong equivalence principle, so that the internal dynamics of a self-gravitating system in free fall depends on the strength of the external gravitational field (the external field effect). We fit rotation curves (RCs) from the SPARC database with a model inspired by Milgromian dynamics (MOND), which relates the outer shape of a RC to the external Newtonian field from the large-scale baryonic matter distribution…</p><p><a href="https://hackerpaper.kaipfister.de/p/2109.04745/">Paper and discussion history</a>.
