An exciting new series of papers published recently published have confirmed the age of our universe. It is 13.8 billion years old. The new findings corroborate the previous findings extracted from the Planck satellite data.
The findings are the result of data from the Atacama Cosmology Telescope (ACT) in Chile, brought together by an international team of astrophysicists. They arrived at this conclusion after studying the photos of the universe in infancy. Another factor that helped reach the findings was the oldest light in the universe.
“In Stony Brook-led work we are restoring the ‘baby photo’ of the universe to its original condition, eliminating the wear and tear of time and space that distorted the image,” explains Professor Neelima Sehgal, a co-author on the papers. “Only by seeing this sharper baby photo or image of the universe, can we more fully understand how our universe was born.”
While it may not settle the debate in the astrophysics community, the results help arrive at a conclusion to which both the Planck and the ACT agree, note the authors.
The series of papers have been published on the arXiv website.
