The universe may be 'younger' than 2 billion years old

To come up with this result, the researchers used new calculations to perform various methods to find the true age of the universe.

"We have great uncertainty about how stars are moving in the galaxy," said the study's lead author, Inh Jee, of the Max Planck Institute.

The researchers say they have used a new technique to give the rate of the expanding universe nearly 18% higher than the research scientists have used since 2000.

The universe is said to have a much 'younger' age than recent calculations.

The expansion of the universe is measured using the Hubble constant (H0) , but according to studies, different techniques "lead to inconsistent estimates" of measurements.

"Ia type supernovae (SNe) observations can be used to measure H0, but this requires an external calibration kit to convert relative distance into absolute distance ," the researchers said. help said.

With new calculations measuring the rate of expansion of the universe, currently 82.4, shows that the universe is approximately 11.4 billion years old. At 13.7 billion years old, the Hubble index is 70.

Scientists estimate the age of the universe by using the motion of stars to measure its rate of expansion. If the universe is expanding faster, it means that it has reached its current size faster and therefore must be relatively younger.

Although the new approach brings a completely different number to the age of the commonly used universe, it is not the only approach to giving different numbers.

In the 1990s, there was a lively astronomical debate about the age of the universe supposedly solved. In 2013, a team of European scientists looked at the radiation left over from the Big Bang and declared its expansion speed slower than 67, while earlier this year, Nobel laureate astrophysicist Adam Riess used NASA's telescope and gave the number 74. And another team earlier this year came up with 73.3.
