‘Impossible’ cluster found in deep space could change what we know about early universe

As we try to peer into the deepest depths of space, we find more and more strange things – and now it appears that researchers have discovered something a little bit impossible. An international team found a galaxy cluster that’s far hotter and older than current theories allow. Essentially, this means that under our current best understanding of cosmology, the cluster is impossible. (Picture: Lingxiao Yuan) This could completely change how we understand our early universe to have evolved.
