Concepción, Chile – According to a new study by astronomers in Chile, dark matter particles that hold the universe together may not be present in this part of the galaxy. Many astronomers and cosmologists are doubting the findings of the study, because of the implications of there being no dark matter holding this part of the Milky Way together. This poses problems to scientists’ understanding of the galaxy, because much of what is known about the cosmos is based upon the existence of an invisible particle whose gravity holds everything together.
