For a long time, the public has been particularly interested in topics such as extraterrestrial life and civilization. Therefore, once international news reports such topics as extraterrestrial life or civilization, this kind of news will become the hottest topic. Not long ago, according to foreign media reports, a British astronomical research team found that there are at least 36 alien civilizations in the Galaxy after using professional equations.
As soon as the news was released, it attracted the attention of many netizens. Everyone was very curious. How did the research group come to this conclusion? If there is an alien civilization in the galaxy, why hasn’t it been discovered yet?
According to the researchers involved in this study, when they explored the alien civilization, they took the earth as the reference system, and considered many factors, such as the formation time of the Milky way, the formation time of the solar system, the position of the solar system in the Milky way, and the time of the earth and life on earth. Considering these complex factors, the researchers calculated a large number of data and finally got a surprising result that there are at least 36 alien civilizations in the galaxy.
Of course, this is only the result of theoretical calculation at present. Whether the actual situation is consistent with the calculated result still needs human beings to explore outer space for a long time in the future. However, if you think deeply about the development of galaxies and solar system, you will find that the results from theoretical calculation are reasonable. First, after 10 billion years of evolution, the Milky way has now produced at least 100 billion stars, half of which are independent, that is, stellar systems.
In the long-term study of the galaxy, astronomers have found that all stellar systems in the galaxy have a “age” difference. Some of them have formed soon after the formation of the galaxy, while others have not formed until after the formation of the galaxy for 5.6 billion years. Therefore, scientists divide the stellar systems in the galaxy into three generations: the first generation, the second generation and the third generation.
The habitable zone of the third generation solar system and the earth like planets in the habitable zone provide the basic conditions for the birth of life, and they also create opportunities for the birth of alien civilization. Therefore, if other star systems outside the solar system have the same internal conditions as the solar system, there may still be alien life, or even alien civilization, in these star systems.
If the calculations of British scientists are consistent with the facts, how strong can alien civilization be? Take the solar system and the earth as an example. As the third generation of stellar system, planets like the earth have emerged in the solar system that can breed human civilization. If other galaxies also belong to the third generation of stellar system, and there are planets in the solar system that are similar to the earth’s condition, then there may be alien civilizations on this planet that are equivalent to human civilization.
However, if the stellar systems with alien civilization are the second generation or the first generation, they may be more civilized than human civilization. In addition, according to this calculation, the closest alien civilization to human beings may be 17000 light-years away, which can also explain why human beings have been exploring hard, but have not found any trace of them.
