An American study reveals the age of the universe and the speed of its expansion


Washington – Arabs today
A recent study conducted by researchers in the United States revealed that the age of the universe is 13.77 billion years. Radio Monte Carlo reported, Monday, that the researchers in charge of the study reached this conclusion using data from the Atacama Cosmology Telescope in Chile. Determining the exact age of the universe is a factor. Important for scientists trying to understand the evolution of the universe and the speed of its expansion. According to the “Axios” website, the results of the study were published as part of a detailed research in the Journal of Cosmology and Astrophysics. By determining the age of the universe, researchers working at Cornell University in the United States were able to estimate the speed of the expansion of the universe, which is known as the “Hubble constant.” The speed of the expansion of the universe is 42 miles per second per megaparsec. It is noteworthy that reaching the age of the universe remained a matter that aroused the interest of researchers, but the calculations did not begin in earnest until the 1950s, when astrophysicists for the first time determined an accurate value relative to the Hubble constant.
