An international research group has recalculated the age of the universe. Using the Atacama Cosmology Telescope in Chile, researchers announced that the universe is 13.77 billion years old.

A group of international astronomers announced the results of a long-running study of recalculating the age of the universe. According to the article published in the Journal of Cosmology and Astroparticle Physics, the age of the universe was calculated to be about 13.77 billion years. This figure could be 40 million more or less, the researchers said.

The contradiction that arose in 2019 was ended
In astronomy, there has actually been a long-standing consensus about the age of the universe on the 13.7 billion figure. The space observer Planck, belonging to the European Space Agency, analyzed the Big Bang remains for four years between 2009 and 2013 and determined the age of the universe as approximately 13.79 billion. But interestingly, in 2019, a different research group claimed that the Planck team’s conclusion was wrong, calculating that the universe was hundreds of millions of years younger than thought. The scientists, who are the subject of our news, want to do a new study and put an end to the contradiction.

Using the capabilities of the Atacama Cosmology Telescope (ACT) in Chile for the new study, the research team analyzed the oldest lights of the universe from the Big Bang, reaching a result of 13.77 billion years. “We have reached a conclusion that Planck and ACT can agree. The fact that both studies yielded similar results reflects the fact that these difficult measurements are reliable,” said Simone Aiola, co-author of the study, who made some statements on the subject. used the expressions.

The calculations made by the researchers also revealed the expansion rate of the universe (Hubble constant) along with the age of the universe. According to ACT’s data, the Hubble constant was calculated as 67.6 kilometers per second per megaparsec. In other words, an object 1 megaparsec (3.26 million light years) from Earth is moving away from Earth at a speed of 67.6 kilometers per second. ACT’s new result is very close to the result of 67.4 kilometers per second per megaparsec previously calculated by the Planck satellite.
