As detailed in a paper published the journal Nature, they discovered an extremely hot galaxy cluster that’s far hotter and older than current theories allow. In other words, the discovered cluster is, under our current best understanding of cosmology, impossible — which could upend our current understanding of how the early universe evolved. The team found the strange readings when they analyzed observations by the Atacama Large Millimeter/submillimeter Array (ALMA) in the Atacama desert in Chile that examined a “baby” galaxy cluster called SPT2349-56. The research suggests galaxy clusters evolve in a far more explosive manner than previously thought, aided by gravitational interactions between multiple supermassive black holes. “These massive galaxies mostly reside in clusters, and their evolution is heavily shaped by the very strong environment of the clusters as they form, including the intracluster medium.”More on galaxy clusters: Scientists Intrigued by Bridge of Dark Matter Inside Huge Galaxy Cluster
