Can energy content of a galaxy cluster account for its dark matter mass?

07 January 2019 0 9K Report

El Gordo Galaxy Cluster has an estimated mass of 6 x 1045 kg. It is believed that 90% of mass within galaxy clusters is because of dark matter. Therefore, in case of El Gordo Galaxy Cluster, 5.4 x 1045 kg is the mass of dark matter. If this galaxy cluster has an energy content of 4.86 x 1062 J, can this much amount of energy be responsible for imparting mass equivalent to the mass of dark matter within this cluster?
