A team of researchers from the University of Tokyo in Japan has revealed dozens of massive new galaxies formed early in the history of the universe, only about two billion years after its inception, and will change the physical models that explain the evolution of the entire universe.
Researchers from the university's astrophysics department spotted 39 massive galaxies so active that one could create 1,000 new stars like the Sun each year, according to the study, published August 7 in the journal Nature.
As a first step several years ago, the research team used the US space agency's Spitzer Space Telescope, which takes pictures in the infrared range. .
This prompted researchers to use the Atacama Observatory Group (ALMA), a matrix of radio telescopes located in the Atacama Desert in northern Chile, which confirmed the results of so many galaxies.
In fact, it is not possible to observe these galaxies in the visible light range, so the Hubble telescope could not detect them. They are so far away that their light dims so strongly that they shift to other ranges of the electromagnetic spectrum.
This new discovery opens a door for scientists to better examine the evolution of galaxies in the early period of the history of the universe, as well as an opportunity to examine the evolution of giant black holes that are located in the center of each, and their role in moving the universe during that period.
On the other hand, the presence of so many galaxies in the early period of the universe's history contradicts the expectations of contemporary physical models that explain the evolution of the universe. More precisely, these results mean that the previously calculated amount of dark matter is inaccurate, because it is based on the presence of fewer galaxies, while this is not true.
But what is most inviting is that this kind of scientific collaboration between multinational research teams and telescopes operating in various scopes is able to enrich the global scientific clan day by day so that the more cooperative we are, the more revolutionary the results.
