Mysterious Force Halts Cosmic Structure Growth
Scientists from the University of Michigan have discovered that the growth of large cosmic structures, such as galaxy clusters and filaments, is slower than predicted by the standard model of cosmology based on Einstein's theory of general relativity. This challenges our understanding of the universe and could be explained by the presence of a new type of dark matter or dark energy, or a modification of our understanding of gravity. The findings could help explain the sigma-8 tension, a discrepancy in the distribution of matter in the universe.
