We Could Share our Universe with More Than 30 Alien Species

Almost 500 years ago, Nikolai Copernicus, then Giordano Bruno questioned the place of the human species in the Universe. They thus assumed that other worlds exist, and the Inquisition promptly fell upon the two tinkers. Even the idea that the Sun does not revolve around our planet, and that other planets exist in the Universe was considered to be a kind of thought crime during the Rennaisance. Today, in contrast, robotic vehicles go through space, and people often live in the orbit of our planet, on the International Space Station. However, although we have discovered over 4,000 exoplanets, we were not able to find clues regarding the existence of alien life. There is the obvious question: what does all of this even mean? Can we already draw the intuitive conclusion that we are alone in the Universe? Scientists affiliated with the University of Nottingham performed a study on the matter and their conclusion is that over 30 intelligent civilizations could potentially exist in the Milky Way.

Personally, when I think about life outside our planet, the words of Sir Charles Arthur Clark, the well-known science fiction writer, tend to come to mind: “There are two possibilities: either we are alone in the Universe, or not. Both are equally terrible.” Regardless of the psychological thriller involved by the search of extraterrestrial life, researchers all around the globe continue. The simple fact that there are 200 thousand galaxies that can be taken with the Hubble Space Telescope makes us dumbfounded. What’s more, the size of the Universe is just one of many things we do not know about the world we live in. Through the use of science, we have managed to send a person into space, send actual robots to the closest planets and even send one of them in the general direction of the Sun.
