Scientists have determined that the universe is 13.8 billion years old

The universe is about 13.8 billion years old, according to new research recently published by the International Team of Astrophysicists.

Although this estimate of the age of the universe is already known, in recent years, other scientific measurements have suggested that the universe is hundreds of millions of years older than this.

Scientists have studied the image of the oldest light in the universe to confirm that it is 13.8 billion years old.

This light, known as the "afterglow" of the Big Bang, is the cosmic microwave background, 380,000 years after the creation of the universe when protons and electrons first joined atoms.

Getting the best image of the baby universe can help scientists better understand the origin of the universe, where we came from, where we are going, how and when the universe will end, according to a statement from Stony Brook University.

"We are restoring the 'baby picture' of the universe to its original state, removing the wear and tear of time and space that distorts the image," explained Neelima Sehgal, co-author of the paper, astronomer Neelima Sehgal.

"Only by looking at this sharp baby picture or image of the universe can we fully understand how our universe was born," Sehgal said.

Using observations from the Atacama Cosmology Telescope (ACT) in Chile, the new findings are consistent with measurements of Planck satellite data of the same ancient light.

The ACT team estimates the age of the universe by measuring its ancient light. Other scientific groups measure galaxies to estimate the age of the universe.

Simon Iola, the first author of one of the new papers on the findings in the Princeton University statement, said the new research would mark a new turning point in the ongoing debate in the celestial physical community about the age of the universe.

Iola, a researcher at the Center for Computational Astrophysics at the Flatiron Institute in New York City, said, "We now come up with an answer, where Planck and the ACT agree. It speaks to the fact that these difficult measurements are reliable."

The ACT research team is an international collaboration of scientists from 41 organizations from seven countries.
