The remarks of an unprecedented resolution now provide more precision on the age of the universe. According to astronomers, it is 13.77 billion years old, up to 40 million years old.
determined, it’s not simple. I’ve been working there for a long time. Today, the new comments seem to want to make everyone agree. Of (United States) yes 13.77 billion years, to the nearest 40 million years.
To arrive at this estimate, astronomers relied on data fromcollected by cosmological analysis of Atacama (ACT, Chile) between 2013 and 2016. And joins the values offered by and measurements made on the same background diffused by the space observer of the European Space Agency ( ) between 2009 and 2013.
Towards a revolution for cosmology?
Remember that in 2019, a, based on measurements of of , had estimated that the universe must be hundreds of millions of years younger. They had argued that – which measures to which our Universe expands – was equal to about 74 kilometers per second per megaparsec. Much more than the 67.4 or 67.6 km / s / Mpc granted by Planck or Cornell University researchers.
This difference in measurements raises the question of the accuracy of the various measurements. But the fact that for the first time independent measurements performed on, give the same result, while more local measurements always lead to a younger age, it could be a sign that we could be at of a discovery that will change us .
Age of the Universe: 13-14 billion years
Hubble’s new observations confirm a 13-14 billion-year-old universe. AuscultândM4, the 7000 of into the , astronomers have detected the oldest in the universe, of 30 whose temperature and age were determined. These stars are 12-13 billion years old. Star life cycle models claim that they are early formed 1 billion years later . Suddenly, the universe would be 13 to 14 billion years old.

To our knowledge, since the Big Bang, the Universe has not stopped growing, but at a non-constant rate of expansion. Today the universe continues to advance, but a mysterious onedarkness (repulsive force) tends to accelerate this expansion.
