Radio signals came from the center of the Galaxy and then mysteriously disappeared! Academician: I believe there are aliens

Radio signals came from the center of the Milky Way

According to the january 17, 2022 report, researchers in 2020 to the Australian square kilometer array pathfinder (ASKAP) data obtained, the results found that a celestial body in 2020 throughout the year of 2020 emitted a strong radio wave, in a total of 9 months to observe a total of 6 signals, this signal regular irregularity and signal polarization degree is extremely high, is the researchers have never encountered. Moreover, the researchers did not find corresponding objects in the X-ray, visible or near-infrared bands. The radio signal then mysteriously disappeared, and even though the researchers searched for months with two different radio telescopes, they didn't find it again. About a year after it was first discovered, the radio signal suddenly reappeared, and then mysteriously disappeared in less than a day.

What's going on? Mysterious radio signals from the depths of the galaxy appear frequently and then suddenly disappear, are they really aliens calling us? Tara Murphy, a professor at the University of Sydney, said it was unclear exactly what the signal was, but the researchers believed it was not an ordinary dead star, and might fall into a rare category of mysterious signal sources from the galactic core, calling it the "Galactic Center Radio Transient" (GCRT). Scientists have only found three similar objects before. While it's unclear exactly what this signal is, Tara Murphy is "100 percent sure" that the signals are not coming from aliens, as tech signals generally cover a narrower frequency range, just like our human radio broadcasts.

Aliens will not really exist

Since humans have created advanced telescopes and other equipment, our field of vision has been able to extend to the distant depths of the universe, such as hubble telescope and James Webb telescope and other devices can see tens of billions of light-years away. It is also with the help of these advanced equipment that we have seen an unprecedented scene, and there are some indications that our planet may not be the only habitable planet, and we humans may not be the only intelligent civilization.

It is very simple, there are eight planets in our solar system, as well as a large number of satellites orbiting these planets, although the Earth is the only planet we currently know of life, but many planets in the solar system have the potential to breed life, such as Mars, Europa, Titan, etc., in these planets there may be some unknown alien life. If you look at the entire Milky Way, there are countless coefficients of stars like the solar system, and it is reasonable to say that habitable planets like Earth are hundreds of millions. Earth is capable of having the origin of life, and those potentially habitable planets can, in principle, have similar origins of life, and may even have aliens who are more advanced than us humans.

In 2021, scientists selected 24 "super-habitable" planets from more than 4,000 known exoplanets, and these super-habitable planets also have superior environments, such as oxygen levels in the atmosphere between 25% and 30%, are slightly larger than Earth, are slightly warmer than Earth, and orbit a star that is milder than the Sun, which means that these "super-habitable" planets will live longer than Earth. Scientists believe that living on these "super-habitable" planets may be more comfortable than Earth.

Although we have not yet found the mechanism of the origin of life on Earth, known information shows that primitive microorganisms appeared on The Earth more than 3 billion years ago, and then these microorganisms slowly evolved towards more advanced, complex species, and after more than 3 billion years of evolution, finally there was a vibrant scene that we see now. Those "super-habitable" planets have been around for much longer than Earth, and there is plenty of time for potential extraterrestrial life to evolve in a high-level direction, and it should theoretically be possible for advanced aliens to emerge. Wu Xiangping, an academician of the Chinese Academy of Sciences and an astrophysicist, once said in the live broadcast of the Chinese Academy of Sciences' 2022 New Year's Eve speech that he believes in extraterrestrial life and aliens.

What would a high-level alien look like?

So far, we can only speculate on this question, because we don't know if aliens exist or what form these potential extraterrestrial life will take. In some science fiction films, we can see that the appearance of imaginary aliens and the appearance of our humans are relatively different, after all, life is very wonderful, even in different parts of the earth, there are differences in human skin color, let alone on different planets. So if there are advanced aliens, will their level of development subvert our cognition?

In fact, there is no fully accepted theory of the level of development of these potential aliens, because no one knows whether aliens exist or not. However, scientists believe that the higher the level of civilization, the greater their scope of influence. Just as the civilization level of human beings in primitive society was very low, the scope of influence was very small, with the development of human society, the scope of influence continued to expand, and now we can already affect the world and even spread to space. If there were aliens more advanced than humans, their sphere of influence would cover the star system or the Milky Way. Based on the amount of energy that a civilization can use to communicate with the exoplanets, the Kardashev level is based on the number of civilizations that can be divided into 3 levels:

Type I civilization: This level of civilization can live in the total energy of the inhabited planet and the surrounding satellites, for example, a civilization that reaches this level can master the energy of planets like Earth and the Moon.

Type II civilization: This level of civilization can control the energy of the entire star system, which is more advanced than the type I civilization.

Type III Civilization: This level of civilization will be more advanced and will be able to use all the energy of the galaxy.

If we judge the level of development of our human beings according to this level of civilization, we will not even be able to reach the lowest level of Type I civilization at this stage. And those aliens who can achieve interstellar flight to Earth are estimated to reach the level of Type II or even Type III civilizations, and if there are such advanced aliens, then we humans will be vulnerable in front of their eyes. Therefore, some scientists do not recommend that we take the initiative to contact these potential aliens, for fear that it will bring disaster to the earth.
