Dark Matter Mystery Deepens

After completing a recent study, the mystery surrounding dark matter has been deepened. Matt Walker claims that after completing this study, we know less about dark matter than we did before. Simulations show that dark matter should be densely packed in the center of galaxies. However, new measurements of two dwarf galaxies show that they contain a smooth distribution of dark matter. This suggests that the standard cosmological model may be wrong. "Our measurements contradict a basic prediction about the structure of cold dark matter in dwarf galaxies. Unless or until theorists can modify that prediction, cold dark matter is inconsistent with our observational data" Walker goes on to say. These results make dwarf planets ideal targets for study for astronomers seeking to study dark matter. The new measurements lead to new possibilities that either normal matter affects dark matter more than expected or dark matter isn't cold.
