One of the proofs of the Big Bang theory, which suggests that the universe was created by the sudden expansion of an infinitely small and infinitely dense point in space, is the existence of relic radiation. It is considered a kind of light echo of the Big Bang. Now astrophysicists have found out that this radiation has another source. The study was published in the journal Nuclear Physics B. The faint background light that has been spreading through space for more than 13 billion years has been around since almost the beginning of the universe and is called the cosmic microwave background radiation. It can be detected by the most powerful telescopes. Now, astrophysicists have conducted a study that suggests that this radiation may not exist at all. Astrophysicists came to this conclusion after studying some of the very first galaxies. The study showed that these galaxies may be the source of either all of the relic radiation, or at least part of it. This means that the relic radiation may not be associated with the Big Bang, and this calls into question the correctness of the standard cosmological model, which explains the development of the Universe since its birth.

Scientists previously knew that the first galaxies were elliptical in shape, but new observations have shown that these galaxies were created much earlier and were fully formed in a shorter period of time than theoretical models predicted. This changes the way radiation is transmitted throughout the universe and indicates that galaxy formation occurred more quickly than scientists thought. Because the Universe has been expanding since its birth, the distances between galaxies have increased. Astrophysicists have measured the distances between the first elliptical galaxies and, knowing their characteristics, have been able to determine when they were created. Researchers believe that in the early universe, these galaxies received a lot of the gas needed to form stars, and therefore, relatively quickly, over a few hundred million years, they created a lot of bright stars. And the light from these stars may actually be relic radiation, either entirely or partially. Astrophysicists suggest that between 1.4% and 100% of the cosmic microwave background radiation can be explained by the light of stars in ancient galaxies. The new discovery means the Big Bang theory is losing one of its leading pieces of evidence, and scientists believe the standard cosmological model will have to change. At the same time, astrophysicists acknowledge that this is only the beginning of a large-scale observation of the early Universe, but the early data suggests that we may be misunderstanding some key aspects of the cosmos.
