Astronomers have discovered that there may be a missing ingredient in our cosmic recipe of how dark matter behaves

In measuring how dark matter's gravity distorts space, researchers found that small-scale concentrations of dark matter in clusters produce distortions 10 times stronger than expected. This evidence is based on observations of several massive galaxy clusters by Hubble and the European Southern Obser...
