Are there really aliens in the universe? Many people think there is none. Judging from the current level of human science and technology, the earth is the only planet in the universe where there is a living body. In the past, due to the lack of advanced equipment and technical difficulties, when you mentioned that there are aliens in the universe, you will be mercilessly ridiculed by others. But experts have come forward to speak, and they believe that there are aliens in the universe.
In the New Year's Eve live lecture, Academician Wu Xiangping, an astrophysicist of the Chinese Academy of Sciences, made a statement, and according to his astronomy major, he first said that he believed in the existence of aliens. In fact, we think a little, the universe is a lot of planets exist in the vast universe, it is impossible for only the earth to give birth to life, but with the current level of science and technology, it is difficult to find other life forms in the universe, even if we find, it is difficult for us to communicate and contact with them. Judging from this statement of the five academicians, in fact, he did not give a positive attitude, but it was overly understood by some people as a human being.
The discovery of the alien academician mentioned a mysterious signal from the universe in his speech, saying that australian astronomers used astronomical radio telescopes to receive signals from another planet, with a frequency of 882 megahertz, and the same frequency as our mobile phones, which was mistaken by those people for signals transmitted from another planet. But in reality, time is not recently discovered. As early as 2019, there were rumors that Earth received signals from other planets. However, this news was confirmed in October 2021, which is a disturbing signal from the surface of the earth, and has nothing to do with the existence of life on other planets. There are always two factions of people on Earth about the existence of aliens, some of whom believe that there are countless galaxies in the universe similar to the Milky Way, and there are hundreds of billions of sun-like stars in the Milky Way. As far as our earth is concerned, just orbiting the sun has produced such a variety of life, then there will be many Earth-like planets in the universe moving around different stars. And these terrestrial planets, as long as they have elements necessary for life, such as water temperature, may give birth to alien civilizations.
But people who think that aliens don't exist say that we have been exploring since the development of technology, trying to find signs that there are aliens, but the clues found since the word began to excavate are either artificial or unable to explain the reason. Until now, there has been no evidence that there are aliens in the universe. To this end, the United States has also set up a special investigation organization to find alien signals, but no progress has been found.
Generally used to search for extraterrestrial signals, radio telescopes are essential, it is a very important research tool. To date, he has made numerous contributions to the astronomical industry. Chinese elements have also found a lot of extraterrestrial signals, to know that every day on the earth will receive a lot of different alien signals, but most of them are not identified by yiyi, because most of them are false signals, even if they are investigated, in the end, no trace of aliens has been found. There is an endless discussion about aliens, and a little meteor will find that many photos sent out under the banner of aliens are mostly formed. These people always like to be highly hyped to satisfy people's curiosity, and some people simply use their imagination to depict something they think is an alien, but these do not explain the problem, aliens are just a vague concept for most people. At the current level of science and technology, it will take a long time to explore the vast expanse of outer space. However, according to the perspective of big data, if only humans exist in the vast universe, this probability may be almost zero, after all, the universe is too big. In the same way, with the development of science and technology, we have gone from walking into astronomy to today's peering into the universe, and I believe that in the near future we may actually be able to find and contact these distant alien civilizations.
