Before you decide that the author of this article is a crazy conspiracy theorist, I did not come up with that. These are scientists. They claim extraterrestrials exist and probably already visited our planet. Maybe they even miss us. Think for yourself – what is the likelihood that you and I are the only intelligent beings in the galaxy, let alone the universe? American scientists claim to have found the answer to the question of the Italian physicist Enrico Fermi: "Where is everything?" This puzzle is known as the Fermi paradox. But how have scientists managed to find the answer to such a complex question?
Scientists have decided the Fermi paradox
In 1920 Albert Einstein rightly remarked: "Why should Earth be the only planet on which there is life?" American scientists also mean this. Experts have published their research in the prestigious journal The Astronomical Journal. Scientists believe that they have developed a solution to the Fermi paradox that sounds like aliens exist but do not want to communicate with us. Or maybe they visited the Earth billions of years ago and see no reason to return.
Scientists have come to the conclusion that there are several intelligent life forms in our galaxy. The lead author of the study, Jonathan Carroll-Nellenbeck, said in an interview with Business Insider, "If you disregard the movement of the stars when you try to solve the Fermi paradox, you have one of two things: either nobody leaves ours Planet, or we are indeed the only technological civilization in the galaxy ".
The researchers' theory is based on the fact that stars and planets spin at different speeds and in different directions around the center of the Milky Way. From time to time, stars and planets are not far apart, so scientists believe extraterrestrials can travel to places in the galaxy closer to them. But for this type of travel, civilizations need more time to settle in the galaxy than previously thought. This is very interesting, so I suggest discussing this in our telegram chat.
Taking this into account, scientists believe that aliens may not have reached us yet, or if they had already done so, they could visit Earth long before you and I evolved.
The scientists' findings are supported by Harvard University's director of astronomy, Israeli physicist Avi Loeb. He did not participate in the study, but for many years searched for life outside our planet and authored more than 500 scientific papers. According to Loeb, the situation is made more difficult by the fact that we have no indications of alien life forms. We have not detected a single signal from distant stars in our galaxy and found no traces of alien visits to our planet.
The question is, in the opinion of the scientist, what to do with this lack of evidence. "I came to the conclusion that we should continue to seek evidence because we can find it in the most unexpected places," Loeb said. The physicist proposes not to pay attention to speculators and conspiracy theorists, but to continue to search for answers and research. In the end, there is only one reality.
How many civilizations are there?
If you starred in the sci-fi film Contact with Jodie Foster and Matthew McConaughey in 1996, you can assume that alien civilizations are not permanent if they exist. "Contact" is based on the eponymous book by the astronomer and popularizer of science Karl Sagan. The novel tells the story of the scientifically most real contact between humanity and a foreign civilization. One of the main questions asked of the main characters is the question of how developed civilizations survived scientific and technological progress and did not destroy themselves.
By the way, even more amazing theories about life in the vastness of the universe can be found on our channel in Yandex.Zen.
Avi Loeb believes that other civilizations could suffer this sad fate. However, this does not mean that we can not find evidence of their existence. After all, many studies in this area do not properly consider the movement of the Milky Way.
However, if a foreign civilization exists long enough and has not been forgotten before the next inhabited star system approaches its planet, such a civilization may vanish before the aliens cross the boundaries of their solar system.
And how many intelligent civilizations do you think exist in our galaxy?
