Observations of unprecedented resolution now provide greater accuracy over the age of the universe. According to astronomers, it is 13.77 billion years old, within 40 million years.
determine the, It is not easy. Been working there for a long time. Today, everyone wants to agree with the new comments. Of (United States) give 13.77 billion years, to the nearest 40 million years.
To arrive at this estimate, astronomers relied on the dataCollected by Cosmological analysis of Atacama (ACT, Chile) between 2013 and 2016. And they connect to the values it provides And measurements made on the same diffused background by the Space Observatory European Space Agency ( ) Between 2009 and 2013.
Towards a revolution for cosmology?
Remember that in 2019, A., Is based on the measurement of Of , Had estimated that the universe should be millions of years younger. He argued that – Measures The expansion of our Universe – was equal to 74 kilometers per second per megacopers. 67.4 or 67.6 km / s / MCP given by Planck or by Cornell University researchers.
This difference between measurements calls into question the accuracy of various measurements. But on the fact that independent measurements were made for the first timeGive the same result, while more local measurements always lead to a younger lifespan, an indication that we may be at With a search that will change us .
Age of the universe: 13 to 14 billion years
Hubble’s new observations confirm a universe between 13 and 14 billion years old. By AuscultatingM4 at 7000 Of In , Astronomers have detected The oldest in the universe, Of 30 whose temperature and age have been determined. These stars are 12 to 13 billion years old. The model of the life cycle of stars argues that these are early Were made after 1 billion years . Suddenly, the universe will be 13 to 14 billion years old.

According to our knowledge, since the Big Bang, the universe has not stopped growing, but rather with a constant speed of expansion. Today the universe continues to move forward, but there is a mysteriousDarkness (repulsive force) accelerates this expansion.
