Abstract

The first x-ray survey of the universe in decades, conducted by the eROSITA mission, has cataloged and measured clusters of galaxies, providing insights into the universe's expansion. The survey, which includes data from 900,000 x-ray sources, has confirmed that the universe is as lumpy as predicted by the standard cosmological theory. The eROSITA team also measured the evolution of the universe using a subset of 12,000 galaxy clusters, finding that the universe consists of approximately 5% normal matter, 25% dark matter, and 70% dark energy. The survey's findings have implications for understanding the Hubble constant and the clumpiness of the universe, but further research is needed to resolve discrepancies with other studies.
