Radio signals from an alien civilization: this is how the feedback is set up

Radio signals from an alien civilization: this is how the feedback is set up

Agree that you should look for news in order to be able to post something and meet your needs. Well, there is never enough time. But the whole thing does not justify writing nonsense. Watch recent statements about the “honorable scientist” he declared in the line of duty, in an article published in temper natureto discover extraterrestrial radio signals of possible “strange” origin. But please!

The classic recipe for packaging a cool info (fairly free translation for fake news) was followed flawlessly.

Take a subject that can be defined as “scientist”. If it’s Chinese, the better. In this case, it is the professor Zhang Tongji, head of the China Research Group for Research on Extraterrestrial Civilizations at Beijing Normal University, who works with the FAST telescope, a technological marvel. The world’s largest technology-based radio telescope full hole (ie it is a full disk). FAST stands for Five hundred meters long spherical radio telescope: a spherical telescope with a diameter of 500 meters. Nicknamed Tianyan (天, lit. “Heavenly Eye of Heaven).

Then announce it temper nature – A respected and very serious scientific journal – published scientific communications of the aforementioned scientist which states that, playing with FAST, signals of probable origin have been recorded alien. According to other prominent journalists, the news of the registration of two “suspicious” signals was published in 2020, while a third signal was collected during this year, in science and technology news. If you type the name of the Official Gazette of the Ministry of Science and Technology of China into the “Science and Technology News” search engine, you will be finished on this sitewhich is quite another thing.

However, the boyata The information is ready. Something real mixed with a lot of creativity. Everything is elegantly packaged and that’s it: we talk about it and it reads a lot. After Google grinds up its data, anyone who does some research to check for fake news finds it. So that’s right.

but not. temper nature He never posted anything. on me science and technology news If you go looking you won’t find anything. Why removed. It follows from the news that it should not have been given. Which means it’s true. This is where the government came from conspiracy. We’re in for a real touch of genius. Add drama to the above recipe as desired. So it’s all, in addition to being fake news, fueling anonymous conspiracy theorists.

Another interpretation of the more “serious” facts: the news was released too much thus, before being verified, verified and published by a recognized international scientific journal. There is not much about Professor Zhang Tongjie on the net. It is not mentioned. There is not even an article of it. Not personal. His name can only be found on Chinese government websites. It is not his fault. It is a serious people. It is a matter of habit censorship from the middle country. From the SETI Center (Looking for extraterrestrial intelligence?) that he runs at Beijing Normal University shows nothing. Beijing Normal University exists and is more than serious. It is a pity that the Italian journalist translated it to “Normal de Peking”, noting that it is a university similar to the prestigious Università Normale de Pisa. but not. The name “Normal” is traditionally given to the Chinese universities that were responsible for teacher training in primary and secondary schools in the early part of the 20th century.

The signal collected does not contain anything extraterrestrial at all. It is not the technical signature of an alien civilization. Meet Dan Werthimer, a SETI researcher at the University of California, Berkeley (middle of which are thousands of citations, web pages, articles, publications, names, titles, and biographies of those who work there), as well as the author of an article in the publishing cycle where the results of research activities are reported in FAST. Werttimer said, “The signals we have collected so far are all confusion radioThey are not aliens. All are ground.” Professor Chang, who works closely with Werthimer, confirmed this position. It is clear that conspiracy theorists do not believe it.

Radio interference (RFI Radio Frequency Interference) big deal. It is unavoidable when using highly sensitive instruments to pick up very faint signals coming from afar installed on a very noisy planet like Earth. Television and radio signals, cellular phones, radars, and satellites generate significant radio frequency noise.

In the scientific community, no one denies the possibility of discovering strange signals. An advanced space civilization is able to send artificial radio signals into space for detection. We humans have already done it with a message Arecibo 1974, an interstellar radio signal containing information about humanity and Earth.

So far, no wireless signals have been detected that can definitely be considered to come from one Civilization alien. There are billions of planets and as many alien civilizations as possible out there in the universe, as described by the 1961 Frank Drake equation. Yet they don’t appear. Which led to the emergence of the so-called The Fermi Paradox which describes the discrepancy between predictions and mathematical observations. Of the two, the first: Estimates like Drake’s are wrong, or our observation/understanding of the data is incomplete. Or we overestimate the prevalence of intelligent life forms. Perhaps, if the life form is intelligent, it is to the point decide not to show. It is not a good idea to go and wake the sleeping dog. Perhaps none of these civilizations thought of launching the self-replicating probes proposed by von Neumann … We will talk about them again.
