Cosmologists use powerful computer simulations that show that dark matter should be densely packed in the centers of galaxies. Instead, startling new measurements of two dwarf galaxies show that they contain a smooth distribution of dark matter. This suggests that the accepted standard cosmological model may be wrong.
