Constantly a person wonders about his fate in Universewhat will happen after his departure and what will be the future of everything we live today. However, scientists are interested in another question: how did it all begin? And before that? Recent data on gas clouds in space may have provided answers to the question of the origin of our reality.

Based on information from the WM Keck observatory in Hawaii (USA), a group of researchers developed a study that was published in the journal nature by density, mass and size hydrogen clouds ancient – and they may have arisen “together” with big clap.

According to the project, these formations, known as Damping systems Lyman-Alpha (in English: DLAs), may be nearly 11 billion years old, “only” 2.8 billion years younger than the birth of the universe, which occurred on August 13th.

They will function as reservoirs for the primitive gas that “dominated” space after the Big Bang. Some of them would condense into stars and galaxies. Finding these elements is challenging, but with many discoveries, says Rogmon Bordoloi, study author and assistant professor of physics at North Carolina State University.

“DLAs are the key to understanding how galaxies form in the universe,” the scientist commented. “However, they are difficult to observe because the clouds are very scattered and do not emit any light.”

“Therefore, we settled on an extended version of the object. It’s like using a space telescope, which magnifies the perspective and gives us a better view,” he added.

Sophisticated detection and “revolutionary” technology

To detect clouds, even though they are difficult to see, the team used a method that combines light from quasars, which are objects more massive than the sun, with two Milky Way-sized DLAs through gravitational lensing, Bordoloi explained.

“Galaxies with a gravitational lens are those that appear to be stretched out and illuminated. This is because there is a gravitational-massive structure in front of it, which bends the light coming towards us. The most surprising thing about the DLAs that we observed is that they are not unique and have similarities in structure.”

“In both, host formations have been found, and their masses indicate that they contain enough fuel for the next generation of star formation. With this technology at our disposal, we will be able to explore more deeply how stars were born in the early universe. “
