The Habitability of Planets in the Universe

Are we alone in the universe? There is something or someone there. These are ancient questions asked by people from all ages and races. But the first question we should ask is whether it is possible or not. Is there any other planet that can live? What does the planet need to live in? Without a living planet, you can not maintain life in space The pursuit of life in space is long and difficult, and there is no proof that life exists outside the earth. SETI Institute, or search the major searchers of the Foreign Intelligence Institute to search for electromagnetic transmission using various methods.

The earth is the only known example of a planet that can live in our universe. Therefore, we must establish the definition of our lives based on what we see on the earth. The two main prerequisites for living are the existence of liquid water and rock geography (so carbon is readily available). However, whether these requirements can exist on the planet depends on many other factors, such as the characteristics of the atmosphere of the main star and the planet, the location of the planet for a livable area.

There are countless planets that may be suitable for living in the history of the universe. And it suggests that only one of them may appear or may emerge. If only 0.1% of the potentially living planet of our universe has life, it is still a million planets. This idea means there are a few "evolutionary transitions or steps" that need to complete the life on a planet like the earth to communicate with the civilization of other stars. Nonetheless, it may be difficult for intellectual species like us to pass through all these steps. This can explain why we have not seen any other life heard.

Even though resident planets are rare, life is highly unlikely and their incredible numbers suggest that there should be other intellectual lives in the universe. If there is a high possibility that only 0.1% of our galaxies planet is alive, there are one million planets that still have life. As philosopher Nick Bostrom said, this view suggests that planets like the Earth must perform some "evolutionary transitions or steps" before communicating with other stellar civilizations doing. However, obstacles and obstacles may make it impossible for intellectual species like us to complete all these steps. This can explain why we have not seen any other life heard.

There is a convincing reason that scientists have never seen aliens, which indicates that humans are extinct.
