First test of rival to Einstein’s gravity kills off dark matter
Folks, the observation doesn&#x27;t test Verlinde&#x27;s idea, this tests a very general class of models, such as the well-known MOND scheme.<p>&gt; Milgrom, however, supports the work. He also points out that according to his own 2013 analysis of gravitational lensing data in galaxies, MOND produces similarly impressive results as Verlinde’s gravitational model does in Brouwer’s study.<p>(Also: <a href="http:&#x2F;&#x2F;motls.blogspot.ca&#x2F;2016&#x2F;11&#x2F;verlindes-de-sitter-mond-is-highly.html" rel="nofollow">http:&#x2F;&#x2F;motls.blogspot.ca&#x2F;2016&#x2F;11&#x2F;verlindes-de-sitter-mond-is...</a> )<p>This data cannot distinguish between Verlinde and other explanations for MOND-like behavior.  We&#x27;ve long known that MOND seems to fit a <i>subset</i> of all observational data better the dark matter, in particular the Tully–Fisher relation<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Tully–Fisher_relation" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Tully–Fisher_relation</a><p>However, for the rest of the data (e.g., the CMB, large-scale structure, the bullet cluster), MOND is generally considered to give a worse fit than dark matter, or to be silent (because it&#x27;s not obvious how to extend MOND to a complete cosmological theory).  That&#x27;s why experts think the totality of evidence supports dark matter.<p>Nothing has changed.
