Scientists have determined the number of possible alien civilizations in the Milky Way galaxy
New research Milk The way assumes the existence of a large number of civilizations in the galaxy. But only a small part of them can make our connection. From Beijing Pedagogical University the astronomers Wenjie Song and He Gao In their new scientific articles, they assumed that Milk The way in the galaxy 42,777 An alien civilization may exist and one of them is close 2000 il can send us a message within. New research The paradox of Fermi potential solution way can be. According to Fermi’s paradox, if there are many alien civilizations in the galaxy, why haven’t we discovered them yet?
In their new research, Chinese scientists have presented theoretical calculations, which show that there are 42,777 alien civilizations in the Milky Way galaxy. However, this does not mean that all of them have reached the level of technological development to send us a message. However, perhaps most of them are not yet at the level of interstellar travel. There are many unknown factors in the calculations of scientists. However, if these factors were known, they could play an important role in achieving results. To solve the Fermi paradox offer made Great filter According to the hypothesis, a number of factors must be fulfilled in order for a civilization to reach a high level of development.
– There must be a planet on which life can be created
– In any case, life must be created on that planet
– Then a conscious way of life must emerge
– In the end, this type of life may reach the level of development possessed by human civilization or higher.
However, according to this hypothesis, if we have not yet received a message from alien civilizations, it indicates that they have not yet reached the required level of development. In a new study, scientists estimated that more than 42,000 civilizations (which may have statistical errors) 0.1%may have reached the level of development necessary to communicate with other civilizations. For this, alien civilizations must go through a long period of evolution.
According to scientists who conducted a new study, human civilization is close 20It can receive a message from an alien civilization for 00 years. That is a message from at least one civilization. 0.1% is an optimistic indicator for our galaxy. According to pessimistic estimates of scientists, this figure is only 0.01% contane. In this case, the message that human civilization can come from an alien civilization 400,000 years will have to wait. “However, this figure can be considered high. This means that the number of alien civilizations that have reached the required level of technical development is less. Accordingly, the probability of receiving a message from such a civilization is very low, “the scientists said.
