Scientists have managed to measure the amount of matter in the universe for the first time

Experts at the University of California have created a method that measures the amount of matter in the universe. Thus, they managed to achieve one of the main goals in cosmology – for the first time to calculate the amount of matter in the entire universe.

According to experts, the share of matter accounts for about 31% of the total amount of energy and matter in outer space, while the rest of it consists of dark energy. The team of astronomers achieved such results thanks to the creation of a cosmological instrument called GalWeight, which allows you to measure the mass of a cluster of galaxies using the orbits of the clusters within them. Subsequently, scientists used their tool to create a public catalog of galaxy clusters. At the final stage of the work, the number of clusters in the new catalog was compared with the results of earlier modeling. And so it turned out to calculate the total amount of matter that is in the entire universe.

According to the authors of this study, a huge advantage of their new method was the fact that they were able to separately calculate the mass of each cluster, and not rely on more indirect methods of a statistical nature.
