text: There are a couple of scientists who challenge that DF2 and DF4 are ordinary-matter-only galaxies, and hence the argument continues. Nevertheless, presuming that the initial measurements of DF2 and DF4 are proper, this brand-new simulation supplies extra proof that dark matter, and not MOND, is an appropriate part of the theory that governs deep space. This simulation may be a little piece of the most significant image of all.
