One of the evidence of the theory of the big explosion, which indicates that the universe was created through the sudden expansion of a small and unlimited small and unlimited point in space, is the presence of radiation.
It is a kind of light echo of the big explosion. Astronomical physicists have now discovered that this radiation has another source. the Ticket It was published in the Journal of Nuclear Physics B.
The light background light that spreads across space for more than 13 billion years has almost existed since the beginning of the universe and is called radiation of the cosmic microwave background. It can be discovered by the strongest telescopes.
Now, astronomical physicists conducted a study indicating that this radiation may not exist at all. Astronomical physicists came to this conclusion after studying some of the first galaxies. The study showed that these galaxies may be a source of all radiation, or at least part of them.
This means that the radiation of antiquities may not be linked to the big explosion, and this calls for questioning the validity of the standard cosmic model, which explains the development of the universe since its birth.
The authors say that based on the data obtained, it may be necessary to rewrite the history of the universe, at least partially.
Scientists previously knew that the first galaxies were oval in shape, but the new notes showed that these galaxies were created much early and were completely formed in a short period of time than expected theoretical models.
This changes the way the radiation is transmitted throughout the universe and indicates that the formation of the galaxy happened more quickly than scientists believed.
Since the universe has been expanded since its birth, the distances between the galaxies have increased. Astronomical physicists measured the distances between the first elliptical galaxies, and learned their characteristics, who were able to determine when they were created.
Researchers believe that in the early universe, these galaxies have received a lot of gas needed to form stars, and therefore, relatively quickly, over a few hundred years, they created a lot of bright stars. The light of these stars may actually be radiant, either completely or partially.
Astronomical physicists suggest that between 1.4 % and 100 % of the cosmic microwave background can be explained by the light of stars in old galaxies.
This new discovery means that the theory of the big explosion loses one of the leading evidence, and scientists believe that the standard cosmic model will have to change.
At the same time, astronomical physicists admit that this is only the beginning of wide -ranging monitoring of the early universe, but early data indicates that we may put a misunderstanding of some of the main aspects of the universe.
