But what astronomers still want to find the most accurate answer. I mean, how old is the universe? Despite previous information revealing that the universe is probably 13,770 million years old, plus or minus 40 million years, or another question is. How much exactly? Makes a collection of tools that answer the question in terms of accuracy. Let’s help measure the distance of galaxies. and the relative expansion rate of the universe AND the time since the universe was born with even a few percent accuracy.
Recently, a research team led by astronomers from the University of Hawaii in the United States. The most accurate galactic distance collection report, Cosmicflows-4. Using eight different methods, the distance to 56,000 galaxies was measured.
The researchers also believe that the Cosmic flows-4 method could be used to study how galaxies move away from each other. As well as the flow that moves along the general expansion of the universe. This is the biggest archive ever.
