From an observatory high above the Atacama Desert in Chile, astronomers have taken a fresh look at the oldest light in the universe. As a result of observations, scientists have named the final age of the universe.
The new estimate, based on data collected by the National Science Foundation’s Atacama Cosmological Telescope (ACT), is in line with an estimate based on the Standard Model of the Universe. In addition, the data is consistent with measurements of the most distant light in the universe, which were collected by the Planck satellite of the European Space Agency. His task was to study the remnants of the Big Bang from 2009 to 2013.
In 2019, a team of researchers measuring the motion of galaxies calculated 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 the Journal of Cosmology and Astroparticle Physics. “Tried on” the data of AST and Planck. Scientists’ observations in Chile, coupled with space geometry, ultimately suggest that the universe is 13.77 billion years old, give or take 40 million.
