Hubble Observations Suggest a Missing Ingredient in Dark Matter Theories

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 Observatory’s Very Large Telescope (VLT) in Chile.
