Japanese scientists from Chiba University managed to measure the total amount of matter in the Universe. They concluded that matter accounts for only one-third of the total amount of matter and energy. To work published In the scientific journal The Astrophysical Journal.
The team used an established technique that involves comparing the number and mass of observed galaxy clusters per unit volume with estimates from computer simulations to determine the total amount of matter in the universe.
Calculations have shown that only 31% of the Universe consists of matter, while the rest consists of dark energy.
Scientists stated that they were able to successfully use spectroscopy to accurately determine the distance to each galaxy cluster for the first time.
The lead author of the study, Dr. Mohamed Abdullah added that the substance itself is heterogeneous. According to cosmologists’ calculations, stars, galaxies, atoms, life, and other material realities make up only 20% of ordinary or “baryonic” matter, with the remaining 80% likely represented by mysterious dark matter, composed of yet-to-be-discovered subatomic matter. particles.
