Quantum Fluctuations and Massive Galaxy Clusters: A Connection?

Astrophysicists have explored the possibility that quantum fluctuations in the early universe could affect the creation of massive cosmological structures, such as heavy galaxy clusters like "El Gordo." The researchers suggest that quantum fluctuations might not only underly the formation of average-sized galaxies and primordial black holes, but also that of massive galaxy clusters. This potential theoretical explanation for the formation of large galaxy clusters appears to be aligned with recent cosmological observations and could also potentially solve other shortcomings of the standard model.
