The Universe Could Be By 2 Billion Year Younger Than Expected

According to previous studies, the Universe is about 13 billion years old. However, as per a new study, the Universe could be by 2 billion years younger than expected. But we have no clues on the precise age of the Universe so that the new calculations might be wrong, as well.

“We have large uncertainty for how the stars are moving in the galaxy,” explained Inh Jee from the Max Plank Institute in Germany and the study’s leading author. The research, by the way, appeared in the journal Science.

Astronomers calculate the age of the Universe by studying the movement of the stars. They also assess the rate of expansion of the Universe by using the same method. The new study measure that the Universe is extending much faster than previously thought, meaning that it’s much younger. It might be by 2 billion years younger than in previous calculation, as per new research.

The Universe Could Be By 2 Billion Year Younger Than Expected

The Hubble Constant is the theory used to measure the age of the Universe. A higher Hubble Constant means that the Universe is younger and fast-expanding. At the moment, the accepted calculation says that the Universe is about 13.7 billion years old, with a Hubble Constant of 70.

However, the new study estimated that the Hubble Constant is, actually, of 82.4, meaning that the Universe is approximately 11.4 billion years old. The latest research is just one of those that remeasured the Hubble Constant. In 1990, for example, another study appeared that estimated the new age of the Universe.

According to Harvard’s scientist Avi Loeb, the new calculations are biased. He said that large error margins limit the correctness of the latest research. “It is difficult to be certain of your conclusions if you use a ruler that you don’t fully understand,” added Avi Loeb.
