🌍 Evidence of extraterrestrial life has fascinated scientists and the general public for decades. The vast and mysterious universe could harbor life forms beyond our planet. Technological advances and recent discoveries have rekindled hopes of finding signs of extraterrestrial life. From searching for microorganisms on Mars to analyzing exoplanets in the habitable zone, astronomers are stepping up their efforts to detect traces of life. Space missions, cutting-edge telescopes, and studies of planetary atmospheres are all valuable tools in this quest. Discovering extraterrestrial life forms would be a major scientific revolution, changing our understanding of the universe and our place in it. Theories abound, hypotheses multiply, but one question remains: are we really alone in the universe? Every day, researchers scan the stars, looking for the slightest clue, hoping one day to answer this fascinating enigma. 🔥 As a reminder, the videos are published on SUNDAYS at 9:00 PM. ------------------------- 💥 Are we alone in the universe? : • This question was generalized by the Italian physicist Enrico Fermi. In 1950, while debating with his friends the possibility of extraterrestrial life, Fermi formulated a series of questions: They are now grouped under the name of the Fermi paradox. Why have we found no trace of extraterrestrial life when the Sun is far from being the oldest star in our Galaxy? Other civilizations must have lived before us. Even if they are now extinct, why have we not detected any trace of them? Humanity on Earth would be, according to scientists, detectable from the confines of the Solar System. Over time, the hypotheses to answer the Fermi paradox have multiplied. The most radical is that the probability of life appearing may ultimately be very low, and that Earth was the only winner of this lottery. Perhaps we are truly, and desperately, alone in the Universe. But there are other hypotheses. Perhaps, everywhere else, life began, but was annihilated by cosmic events. It was therefore never able to reach the advanced stage that we currently know on Earth. Perhaps extraterrestrial life exists, but only in the form of microbial, plant, mineral or animal life. Or perhaps intelligent life does indeed exist, but interstellar travel is impossible, or forbidden by extraterrestrial civilizations. Perhaps extraterrestrials cannot or do not wish to make contact with us. It is likely that they simply have not found us yet. It may even be that we are not even on their list of potentially habitable planets to explore. Perhaps other civilizations have developed differently from ours. They have not developed technology similar to ours, and have therefore designed alternative means of communication for example. Or on the contrary, maybe it is we who are not technologically advanced enough. Maybe we are unable to detect extraterrestrial life. The extraterrestrials send us signals, but we are not able to detect them. Maybe life exists elsewhere, but it is undetectable. For example, at the bottom of an ocean protected by a layer of ice. Maybe on the scale of the Universe, the quest for extraterrestrial life from Earth is still too recent. Maybe we are the first form of intelligent life in the Universe, and others will follow, but our civilization will already be extinct by then. So we will no longer be here to see it. Maybe the extraterrestrials avoid us, because they are afraid of us. Or maybe, that ... the extraterrestrials are already among us ...?
