Astronomers reviewed the age of the Universe and agreed that it is nearly 14 billion years old

The time elapsed since the Big Bang explosion is the age of the Universe. It has always been a fiercely debated topic among scientists.

Now, scientists have taken a fresh new look at the oldest light in the universe from an observatory at Atacama Desert, Chile.

These new observations from the observatory along with a bit of cosmic geometry has unveiled that our very own Universe is 13.77 billion years old (plus-minus forty million years).

Theses new estimates were made using data collected at the National Science Foundation’s ACT (Atacama Cosmology Telescope).

The estimates are consistent with the one provided by standard model of the Universe, along with the measurements of the same light done by European Space Agency’s (ESA) Planck satellite, which measured the Big Bang remnants from 2009 to 2013.

A team of scientists measuring the galaxy movements in 2019 calculated that the Universe is hundreds of millions of years than predicted by Planck team.

This difference indicated that a new model of Universe might be required and triggered the concerns that one of the sets of measurements might not be correct.

But now with this new research, scientists have devised an answer where Planck and ACT agree.
