According to a new study published Thursday in the journal Science, the age of the universe could be two billion years less than what scientists now estimate.
Previous estimates suggested that the universe was 13.7 billion years old, but new research calculates that it could be about 11.4 billion years old.
In recent years, scientists have reopened an astronomical debate that seemed to have settled on the age of the universe, which they appreciate by trying to measure the speed at which the universe is developing.
Some recent calculations suggest that the universe is younger, but other estimates suggest that it could be older, according to the Associated Press.
The massive fluctuations reflect different approaches to the difficult problem of knowing the age of the real universe, and even this new calculation can range from hundreds of millions of years, confirm the researchers.
