Dark Matter Alternative Passes Big Test
&gt; Unlike dark matter models that are often based on fundamental symmetry principles—the new model was not conceived with an underlying theory in mind. However, such a theoretical basis might be uncovered using the new MOND model.<p>I think this is an important thing to keep in mind. Cosmology has a big challenge right now. There is something fundamental in the universe that we don&#x27;t understand. While dark matter is currently our best explanation, it is deeply flawed; it predicts the existence of an entire class of matter that we&#x27;ve been unable to find any physical proof for other than cosmology (and cosmology is the thing we want to explain!). Maybe we haven&#x27;t looked hard enough, maybe we haven&#x27;t look in the right place, or maybe dark matter is just wrong.<p>The CMB has been a huge issue for dark matter alternatives. Previously, only dark matter had a good explanation. If this result holds, it could be an amazing leap forward is outlining the alternative types of theories that could explain cosmology.
