Galaxy Clusters Reveal Fresh Evidence Supporting Dominant Universe Theory

Published

The standard model of cosmology, primarily defined by the Lambda-CDM theory, explains the universe’s evolution, asserting it began with the Big Bang around 13.8 billion years ago. This model emphasizes the universe’s continual expansion and its composition, with approximately 95% consisting of dark matter and dark energy, while only 5% is made up of normal matter. Recent research by physicists from SLAC National Accelerator Laboratory and Stanford University has provided new evidence supporting this model by analyzing the structure of galaxy clusters. They studied X-ray emissions from these clusters to understand their internal matter distribution, focusing on systems in a “relaxed” state where gravitational forces and gas energy are balanced. By comparing real observations with data from simulated galaxies, the researchers established consistent results, confirming that clusters become more centrally concentrated over time. These findings strengthen the Lambda-CDM model, thus contributing to our understanding of cosmic structure. The team plans to enhance their research further by utilizing upcoming projects and space missions for larger datasets, which will refine simulations and assist in identifying alternative cosmological theories. This work is pivotal for expanding knowledge of galaxy clusters and the universe’s fundamental properties.
