There may be evil civilizations in the universe. If aliens are found, human beings may be enslaved or even destroyed!
There are evil civilizations in the universe

Are we humans alone in the universe? Probably not, but that's not the only answer to the questions astronomers are seeking to relate to aliens. While many scientists do their best to reach out to or at least find alien civilizations, others ask key questions: Are we sure we're ready for aliens to find us? If alien life is found, do we try to contact it or make it disappear? Some people think that aliens might not be a threat to us humans, while others have dire thoughts.
Andrew Siemion, director of the Search for Extraterrestrial Intelligence (SETI) research center and director of the Breakthrough Listening project, said: "We cannot fully believe that there is some connection between technological progress and morality, and that there may be evil civilizations elsewhere in the universe. , so we should certainly take this into account when we continue to explore the universe. If we can successfully find it, it will indeed change the world, but there is no guarantee that human civilization will continue to survive.” In short, if alien civilizations really exist , does not rule out the possibility of the existence of an evil civilization.
How do we communicate with aliens?
In 1960, astronomer Frank Drake set out to search for alien signals sent to us from beyond the solar system. At the National Radio Astronomy Observatory in Green Bank, Virginia, Drake used a radio telescope to look at two nearby sun-like stars, Tau Ceti and Epsilon Eridani, and found that they appeared to be habitable planets in the habitable zone. But after 150 hours of observing the star over a four-month period, Drake's initial attempt to find alien life failed. However, the initial observations started the human exploration of extraterrestrial civilizations, and thus the search for extraterrestrial civilizations (SETI) was born.
SETI is based on the idea that not only did life develop on another planet, but it evolved in the same way that life on Earth developed, and has advanced enough to create modern technology. But Siemion said SETI has been listening to the universe to detect the presence of signatures (unnaturally occurring traces) of alien technology, rather than necessarily contacting aliens. In other words, SETI is a passive approach to searching for alien civilizations.
But many SETI astronomers are not satisfied with just scanning with radio waves. They believe that they need to take the initiative. This group of people is called "Alien Intelligence Communication (METI)." The leader of METI is astrobiologist Douglas Vakoch, who wants to reverse the process and let aliens know that we are here. "What would happen if every civilization out there was doing this, we would just be listening instead of transmitting, and it would be a very quiet universe," he said. So in 2017 METI issued its first A radio transmission of the signal, and they're building laser transmitters to carry narrow-bandwidth, fast signals over longer distances.
However, not all of them are willing to transmit our own signals into the universe.
Alien creatures may enslave humans!
There is still a big debate about whether humans should reveal our existence to cosmic civilizations. Is it wise to try to communicate with intelligent life beyond Earth? Although some people advocate positive methods to get in touch with extraterrestrial intelligent life, others oppose communication with extraterrestrial civilizations. They believe that the technology of extraterrestrial creatures is more advanced than that of earth people, and this is likely to enslave earth people or completely destroy them. Earthling.
As a civilization, for the past 100 years, we have been continuously leaking radio signals into the universe, with increasing frequencies. So if another civilization is watching Earth, they will surely see these signals that our planet is exposed, and we have to take into account that a technologically advanced civilization could be evil. Michio Kaku, an astrophysicist at SETI, said: "Personally right now, I think aliens will be friendly, but we can't risk it. very careful."
In fact, this is not the first time that people have warned humans not to actively contact aliens. There may really be a "dark forest law" in the universe. In fact, human beings only need to look at themselves to know what intelligent life may develop into, and even we ourselves do not want to touch it. I can imagine aliens who have exhausted the resources of their home planet and made giant spaceships their homes. Such technologically advanced aliens may become nomads, conquering and colonizing any planet they can come across. From the history of the encounter between different human civilizations, the more advanced civilization will destroy or enslave the lesser civilization. So Hawking once said that if aliens do come to you, I think the result will be similar to Columbus discovering the New World, and the end of the Native Americans is not good.
There is also a short film called "Raka", which tells that the earth was invaded by the alien creatures "lizardmen". They seized human culture and history with more advanced alien civilization, and enslaved or exterminated human beings. Numerous female bodies have become incubators for alien pups. At the same time, they hung tens of thousands of corpses on iconic buildings such as the Eiffel Tower to warn humans.
Optimistic scientists believe that any civilization that can develop interstellar space travel has already advanced to a stage where it does not have to exploit colonies and can use sustainable energy. For the earth civilization, enslaving the colonists and grabbing local resources may be profitable for a while, but for the alien civilization that takes tens of thousands of years to travel in space, it is undoubtedly the practice of killing the chicken and taking the egg.
But no matter what, humans have already sent more than 50 signals to outer space, the earth has long been exposed, and any civilization that may harm the earth already knows that we are here, and it is too late to hide. All you have to do now is get your wine and shotgun ready.
