Are there any aliens? This is a question that everyone wants to ask, not only ordinary people, scientists also have great doubts about this, so do they believe that there are aliens? If aliens here refer to alien intelligent lifeforms, most scientists actually think there are.
From December 29 to 31, 2021, the Chinese Academy of Sciences and the Academy of Sciences of China held a 2022 New Year's Eve scientific lecture, in which Wu Xiangping, an academician of the Chinese Academy of Sciences and an astrophysicist, clearly believed in the existence of aliens in his speech.
In the speech, Academician Wu said that since 1959, people have begun to look for aliens through astronomical telescopes to receive signals, and in the early days, some people have made radio wave receivers the same size as football fields, and on August 15, 1977, they received a signal that has not been deciphered so far, which is believed to be most likely from aliens.
Only two months ago, astronomers used a radio telescope with a diameter of 64 meters in Australia to receive a signal from Proxima Centauri, which is the closest star system to the solar system, only 4.22 light-years, the frequency of this signal is 982 megahertz, which is basically the same frequency as the mobile phone we use, and scientists have also confirmed that the signal is not human interference, so it may be confirmed that it is the first "alien call" received by humans. We may have received a "cell phone signal" from Proxima Centauri.
The Proxima Centauri system is three stars in operation, is considered to be the prototype of Liu Cixin's "Three-Body" science fiction novel, the unnatural signal from this star, can't help but make people a little worried, if the signal is really sent by Proxima Centauri, it means that the "three-body civilization" has been much more advanced than us, Because the signal of our mobile phone frequency is still impossible to be received by a 68-meter radio telescope 4.2 light years away, and the trisolaran civilization can send a strong signal through 4.2 light years, or indicate that it has mastered the scientific and technological achievements that humans have not yet reached, and if the trisolaran civilization really knows the existence of our earth civilization, then some of the plots in Liu Cixin's "Three-Body Problem" may be imaginary or really possible.
Since even academicians of the Chinese Academy of Sciences believe in the existence of aliens, what else do we ordinary people have to say? In fact, measuring the size of the universe, the number of stars, it is difficult to say that there are no aliens in the universe, there are 100 billion to 400 billion stars in the Milky Way alone, the number of planets will only be more, and there are at least 2000 billion galaxies in the observable universe, in such a huge base, it is impossible to have life on our earth, nor can it be only our life on earth that has evolved to the stage of civilization, so if we regard extraterrestrial intelligent life as aliens, We should not or even cannot be alone in the universe.
Some friends do not believe in the existence of aliens, the basis is basically no conclusive evidence to prove the existence of aliens, the "conclusive basis" mentioned here, it should be said that they have seen or touched the aliens, in order to recognize their existence, if this is the standard, then it is indeed impossible to prove the existence of aliens, but this logic is actually incorrect, can not say that something does not exist because we have not seen or touched, everyone has not seen a lot of things, can we say that they do not exist? And although there is no evidence of the "conclusive existence" of aliens, there is no evidence that aliens do not exist, so although the existence of aliens is still a mystery, it is still very likely.
Earlier said wu xiangping academician mentioned the two evidence, that is, the human radio telescope has received two suspected signals from aliens, which can be used as reference evidence, there are many unmanned flying object (UFO) events around the world since ancient times, the US Navy has also released some video data in the past two years, the flying objects shown in the image are indeed beyond the ability of human flying objects, so even if aliens live near us, it is not impossible. If their level of technology is high enough, then even if they live around us, we will not be able to perceive their presence.
About what aliens look like, in fact, the so-called aliens are the possibility of what we think of as "people" look very unlikely, at this point the expression of science fiction movies is not in place, although there have been many kinds of aliens in science fiction movies, but most of them are not out of the category of "human" form, in fact, alien intelligent life forms can even exist in any form, they may be naturally evolved life forms, or it may be computer or mechanical life forms like artificial intelligence products. It may also be an invisible and phaseless quantum life form.
Mr. Yang Zhenning, an authority on world physics, even believes that there is a creator in our world, and he once said such a passage: When I was 20 years old, I thought that I could prove everything about nature with knowledge, but gradually deepened my understanding of nature and felt too much magic in it, I believe that there is a creator in this world.
So what kind of attitude should we adopt toward aliens and alien civilizations? Although we want to have our friends in the universe, the "Law of the Dark Forest of the Universe" mentioned in Liu Cixin's work may also be really effective, which is a law that makes any civilization very terrifying, because only the real cosmic strong can survive, and it is as terrifying as the law of the jungle in nature.
Therefore, for the sake of safety, at this stage, human beings should not be connected with extraterrestrial intelligent life, for all mankind, development is really the last word, which is related to the fate of mankind.
