A Collision Between Gigantic Galaxy Clusters. Too Big, Too Early.
Astronomers have carefully examined a momentous collision between two gigantic galaxy clusters and have found that it's outside of what was predicted in cosmological models. The galactic pile-up occurred when the Universe was half its current age and involved a galaxy cluster with 2,000 trillion times the mass of the Sun. Previous observations of the cluster, nicknamed "El Gordo," had hinted at the cosmological challenges, and this new study uses a more precise measurement of the masses involved in the collision.
Scientists have discovered that cosmic structures grow slower than Einstein's Theory of General Relativity predicts, with dark energy playing a more dominant inhibitory role than previously thought. This finding may reshape our understanding of dark matter, dark energy, and fundamental cosmic theori
