For the first time, a group of cosmologists say they’ve created virtual galaxies inside their computers without any dark matter. Critics of dark matter see it as a win for a controversial model of how our universe formed, called MOND, or Modified Newtonian Dynamics. But this one result isn’t likely to convince most astronomers they should abandon decades of dark matter theory.
Research describing the new simulation is set for publication in the Astrophysical Journal.
