A group of astronomers claim that our universe was born 13.8 billion years ago.
To reach this conclusion, a team of 140 astronomers from 41 organizations and 7 countries used measurements of microwave cosmic background radiation (CMB) – the electromagnetic radiation remaining in the air. interstellar space and galaxies, dating from around 380,000 years after the Big Bang.
The research was carried out on the ALMA telescope located in the Atacama Desert in Chile.
The CMB has long been considered the most important explanation for how the universe began to evolve.
The team’s calculations are consistent with estimates made in 2015 on the basis of data from the Planck satellite of the European Space Agency (ESA).
“Now we have found an answer that Planck and ACT agree on. It is a testament to the fact that these difficult measurements are reliable,” the team stressed.
According to the IBT Times, astronomers have studied parts of space 20 billion light years away and variations in light emitted about 380,000 years after the Big Bang.
The result is an image of a universe 13.8 billion years old.
“The age of the universe shows how quickly the universe is developing,” the researchers said.
Neelima Sehgal, a member of the research team, said he and his colleagues were trying to restore the primitive image of the universe, eliminating the waste of time and space that distorts the image.
“Only by observing this primitive picture or this sharper picture of the universe can we better understand how our universe came into being,” Sehgal said.
