Where are the creatures of space? Scientists from the Extraordinary Science Mediation of the Paris Science City are studying this question which, in addition to feeding the imagination of amateurs and beginners, is a serious issue that is the subject of "many debates".
"When we seek to better understand the universe, we can not avoid the question of whether we are alone in this world," says Florence Roland-Cerso, professor of astronomy and lecturer at the National Gallery of Canada. natural history of France.
"Even if we are looking for something that we do not know if it actually exists, we need to discuss it," said Douglas Fakuch, president of San Francisco-based Mitti International, which specifically addresses messages to others. planets.
In 1950, physicist Enrico Fermi, Nobel laureate, asked "Where are they?" When he was discussing in the canteen of the Los Alamos National Laboratory of the possibility of a life in a place other than Earth, he was surprised that no creature of space was ever still encountered, given the vast universe and age of the Great Galaxy. This question is known as the "Fermi Paradox". Since then, many attempts to connect have been attempted, such as the Brechtro Leesen program led by physicists from the Royal Society of Science Academy in London or the research conducted by the City Research for Extreme Intelligence Institute in California. "The Earth was formed 4.65 billion years ago and the search for space creatures goes back 40 years," says Cyril Berenbaum, astronomer at Science Dome. This section is a film about the "Fermi Paradox" which presents the end of 2020.
Although the quest for extraterrestrial life has not yet borne fruit, human knowledge of the universe has completely changed: in 2014, astronomers discovered the planet Kipler-186p, similar to Earth and located in a habitable zone in relation to its star. Liquid for life.
Since this discovery, evidence has emerged that the Earth is no exception between planets.
"If we visit space creatures one day, I think the result will be similar to what happened when Christopher Columbus arrived on the American continent and that it did not happen. not been positive for indigenous peoples, "said astrophysicist Stephen Hawking in 2010.
According to the astronomer of the National Center for Scientific Research in France, Nicolas Brantzos, "because thousands of civilizations can exist for thousands of years, living alone in the galaxy does not mean that we are the first or nobody in the history of the galaxy. "
