Alien Life – Is It a Myth or a Fact?

Even though the existence of aliens has been viewed as a theory, having no evidence to support it, a recent study has demonstrated that 36 alien civilizations are currently trying to reach our planet by sending beaming radio signals. The research was performed by a team of astronomers from the University of Nottingham whose primary focus was to determine the possibility of alien intelligence to evolve on other planets.

What is even more interesting about this study is the fact that the theories presented take an example from the evolution of humans on Earth. According to the study, the alien populations can send radio signals to the planets in a solar system and are situated at 17.000 light-years away from each other.

Bearing in mind this calculation, an average of 36 alien civilizations might exist throughout the Milky Way. The findings have been published in the Astronomical Journal. The leading authors of the paper have declared that this study has been a thrilling one, given the fact that it manages to answer a question that has always been intriguing. Therefore, there are 36 possible existing civilizations that the humanity can contact.

In addition to this, there might be even more alien forms of life in the Universe, bearing in mind the fact that a population can be formed for five billion years. This method of calculation has been entitled to the Astrobiological Copernican Limit, which proposes two different solutions. One of them refers to the fact that the position of a planet in the proximity of a star is highly important. The other method suggests that the age is the crucial factor, stating that the planet should be 4.5 to 5.5 billion years old, exactly like Earth is.

Another solution that has been taken into consideration is the Drake Equation. Invented back in 1967 by the scientist Frank Drake, another two options are taken into account. The first one states that alien life used to exist, and it became extinct once humans started to evolve. The other one suggests that our planet is unique in its existing forms of life.
