Ever since mankind mastered radio technology, mankind has intended to use radio technology to get in touch with extraterrestrial civilizations. For example, in the late 19th century, physicists continued to send radio signals to the planets Mars and Venus, hoping to get a reply from the inhabitants of Mars or Venus. Of course, we know now that Mars and Venus are devoid of life, so these signals can only echo in the open space on the surface of Mars.
Beginning in the 1960s, mankind began to focus on the search for extraterrestrial civilizations in the universe beyond the solar system. In 1977, mankind discovered a miraculous radio signal. The magic of this radio is that this signal can be interpreted as the word wow after compilation. Therefore, this mysterious extraterrestrial signal is also called a WOW signal. At the same time, in terms of signal strength, the strength of the WOW signal was several times stronger than most natural signals, so scientists at the time suspected that this signal was actually emitted by extraterrestrial intelligent beings.
However, due to the rotation of the Earth, the listening of the WOW signal was soon interrupted. So for many years after that, scientists began to search for the source of the WOW signal, all of which began in 1977. It wasn't until 2022 that humans found the source of the WOW signal through astronomical instruments – 45 years after 1977.
Of course, in the past 45 years, the earth's science and technology have been in an era of rapid change, and at the same time, a large number of scientists in astronomy and physics from various countries have also passed away and a large number have been reborn. However, even so, humanity has not given up searching. Finally, these forty-five years of hard work have not been in vain, and in 2022, things have come to an eyebrow.
Humans determined that the WOW signal was emitted by a galaxy 1,800 light-years away in the constellation Sagittarius. The situation of galaxies is quite similar to that of the solar system, so scientists once wondered: Could it be that there are intelligent beings on this planet, and the intelligent beings of this planet emitted a WOW signal to the solar system and were discovered by humans?
However, if this speculation is true, then it also shows another problem that is very scary: that is, if the WOW signal received by humans in 1977 came from 1800 light-years away, it means that this signal was transmitted in the 2nd century, which is equivalent to the Eastern Han Dynasty in China, and the planet sent a WOW signal to the solar system and was received by humans in 1977.
During the Eastern Han Dynasty, the intelligent creatures of this planet mastered radio technology, so after 1800 years of development, didn't the science and technology of this planet reach a point that is unimaginable to human beings? So, has the civilization of this planet realized interstellar travel? All these have made human beings have to imagine deeply.
However, just when human beings were anxious about the situation on this planet, the continent's Tianyan also intervened in the study of this planet, and in the end, scientists on the continent gave the truth of the matter based on scientific data: that is, the WOW signal does exist, but it is not emitted by intelligent beings. Because the Eye of Heaven has found a dying star in the interior of Sagittarius A. The star produces a large number of cosmic rays, including stable gamma rays. In this context, the radio waves released by this star were picked up by human radio equipment in 1977 and caused an oolong event.
