New estimate based on data collected by the National Atacama Cosmological Telescope (ACT)
In 2019, a group of researchers measuredthe motion of galaxies, estimated that the universe is hundreds of millions of years younger than the Planck team predicted. This discrepancy suggested that a new model of the universe might be required, and raised concerns that one of the sets of measurements might be wrong.
However, a new study published in Journal of Cosmology and Astroparticle Physics. "Tried on" the data from AST and Planck. Observations by scientists in Chile, coupled with space geometry, ultimately suggest that the universe is 13.77 billion years old, give or take 40 million.
