Is the world in a special place in the universe? Cosmological principle can answer

Some experts play by saying that we live in a corner of the universe, because the world is found in a distant area of ​​one of many cosmos galaxies. The Milky Way may seem more important, but it is only because it is the galaxy that we live in and the most examined by scientists. However, it is far from being one person.

Our planet is in a region called the Milky Way, which has approximately 27,000 light years from the Galactic Center. So far, as we understand, the only planet known under conditions suitable for the emergence of lifeDue to the presence of basic chemical elements, water and other basic components.

Currently, scientists are already thinking about the possibility that cosmos, which has conditions suitable for the formation of the basic blocks of life, are other areas of other regions. However, more research is needed in the region to better understand this hypothesis.

Experts examine several outer planets with the potential to host life. As the next Centauri B, only 4.2 light years from Earth. In addition to remote worlds, other celestial bodies also host an underground liquid water ocean under an ice layer and have promising features such as Jupiter’s bear.

Are these and other places really special in the universe? A study The magazine shows that all regions of cosmos, published in Cosmology and Astroparic Physics, may have similar conditions, but this hypothesis can only be confirmed with more data and spatial observation.

To determine whether there is a special place in the universe, scientists analyzed one of the basic principles of cosmology: cosmological principle. Briefly, This concept states that regardless of where it is, the universe offers the same characteristics in any region.

“Cosmological principle is a basic pillar of the standard cosmology model and affects our view of the universe and my place. Therefore, it is essential to develop multiple observational tests that can define and measure possible violations of this basic principle. ”

What is cosmological principle?

The cosmological principle is a basic hypothesis that maintains the idea that the universe is homogeneous and isotropic in large scales.

So far, there is no scientific evidence that proves this principle. However, various observations of cosmos show that the universe has this homogeneity such as cosmic background radiation in the microwave (CMB) cosmic background radiation and distribution of galaxies.

One of the main features of cosmological principle is the idea that the laws of physics are universal. If this is homogeneous on large scales, Then the laws of physics are applied in the same way everywhere and at any time. – After 10 billion years or 5 billion years. So, it shows that there is no special place in the cosmod.

This fundamental hypothesis argues that all the laws of nature are always the same, and that any phenomenon observed in the past can emerge in the same way. Basically, the idea is that the universe behaves equally everywhere and always.

“[Um dos principais pontos] Cosmological principle is that the laws of physics are universal. The same laws and physical models applied on the earth also work in distant stars, galaxies and all parts of the universe – of course it makes our research extremely simplifies our research.

Some recent observations Recommend the existence of anomalies that can challenge the homogeneity of the universe.However, this evidence is not yet certain and requires more data for approval.

Isn’t it special in the universe?

In the last study, The astrophysics team used the standard cosmology model to deepen the understanding of these concepts. This model indicates that the universe has no central or preference aspect, which indicates that it is isotropic.

Researchers have developed a new methodology to test the possible isotropy of the universe, which can use data collected by different space instruments. The European Space Agency (ESA) says Euclid Space Telescope may play an important role in the solution of this mystery.

The new method tries to understand if there are anomalies that can confirm or challenge the cosmological principle from the use of weak gravity lenses.

It occurs when there is a distributed substance between weak gravity lens, observers and galaxies and a background galaxy, such as dark matter,, It causes small deterioration in the visible form of the galaxies.

This phenomenon is different from the powerful gravity lens, which can create multiple images and even raise the light of distant objects; Weak lens only produces fine deterioration.

“Cosmological principle is a type of humility declaration. James Adam, the main author of James Adam, astrophysicist James Adam, South Africa’s Cape Western University, has explored a different method to restrict a different anisotropy containing the so -Conteed weakly gravitational lens.

Scientists have not yet used the method, but they believe that the results can receive two types of answers:

• In the first case, detection of cutting mode and The distribution of matter is homogeneous and the universe follows the cosmological principle;
• In the second option, the important perception of large -scale B mode scissors, There are deviations from the expected isotropyBut this alone does not confirm the anisotropy of the universe. In order to understand the result, it is necessary to associate information.

In the concept of anisotropy, the characteristics of the universe may vary depending on the observation point.. For example, if the expansion of the cosmos occurs faster than others in some regions, the universe will be anisotropic. But so far, no hypothesis has been confirmed.

Space is a environment full of mystery that challenges our cosmos understanding. Would you like to learn more about one of them? Understand how gravity lenses can help transmit energy between stars. Until next time!
