Cosmology for many years has been a great focus of research and observation. Even since time immemorial by ancient populations that studied the lunar phases, stars, eclipses and other phenomena that take place in our immense universe.
Through the ages, thanks to different investigations, different phenomena have been found in the cosmos that have been of great relevance in how the universe has been presented. Cosmology has a great meaning in sciences such as astronomy, physics, philosophy, religion and even esotericism. It has been used since approximately 1731.
Expansion of the universe
It is one of the most impressive discoveries in cosmology, made by the renowned American astronomer, Edwin Powell Hubble, for the year 1927. There he enunciated his well-known law, proving that the universe is expanding and that galaxies move apart with a speed convenient to the path in which it is located.
Another discovery made by Powell Hubble, was that the light found in the vicinity of the Milky Way was not only nebulae. These are galaxies that he decided to call Island Universes. In addition, he denied that this Way was originated by this path of stars. It proved that its origin was caused by the bright star called Andromeda.
A subject that has caused much controversy in cosmology, until its existence was finally discovered recently. In addition to having a close relationship with the Big Bang theory, since after this the world developed in the following years. It also served as proof of the presence of other parallel cosmos, thanks to the space-time differences.
In cosmology, this research determined that, contrary to popular belief, the universe is expanding faster and faster. And this is a consequence of the dark energy that stimulates the universe. This study was made thanks to the observation of supernovae, since due to their great brightness, it was shown that this process occurred in reverse.
It was proved that, just as there is what we can observe, there is matter that is not visible, which was called dark matter. It is also known that it is composed of different elements that we know on earth.
Having been confused with stars, by 1963 quasars were discovered, being an important discovery in cosmology. Since these have great contributions to the study of the universe by circulating electromagnetic radiation.
Space is flat
Research carried out thanks to the Boomerang project, which measured the transformation in cosmic microwaves and which allowed the discovery of space, reaching the conclusion that it is flat. This study was the one that allowed to find the dark energy.
Temperature differences in the cosmic microwave background
Thanks to cosmology, it is known that the cosmic background is unstable, so it is known that the temperature in the tracks of matter is different.
Researchers are convinced that radiation is a consequence of the Big Bang explosion. Fitting with the black body phenomenon.
Microwave background radiation
A study discovered by chance by two experts in cosmology, when in other casual studies they captured the static of the cosmos. This, thanks to the great explosion of the Big Bang.
Constantly showing that the cosmos lives in a transition and in expansion, thanks to the scientists who are dedicated to this field, they have been able to discover these curious anomalies that, despite the distance, are no longer so impossible to investigate.
Although the universe is still a largely unknown area for human beings, every day great scientists strive to study and understand the cosmos, seeking to expand the frontiers of the human race in the near future.
