Use the game's strategy to find aliens
Introduction: There is a new theory in search of aliens. Like game interactions, you're going to send a signal, and the other person is just ready to accept it, or vice versa.

Recently, a new approach to the use of "game theory" game interaction strategies to find extraterrestrial intelligent life has been proposed.
The study was carried out by Astrophysicist Eamon Kerrings at the University of Manchester in the United Kingdom, and the results of the study were published in the journal Journal of Astronomy.
How game theory can help us find extraterrestrial life
Is there extraterrestrial life in our galaxy? This is an unanswered question that scientists working on the Extraterrestrial Intelligent Life Search Program (SETI) have been trying to figure out for years.
Dr. Kellings's theory is that both scientists on Earth and scientists on alien planets are looking for each other—just like the two parties involved in the game in game theory, who do not communicate directly with each other, but have to fight together to win.
Dr. Collins calls his theory "mutual discoverability." He believes that it is necessary to start with planets that have a high probability of discovering life on Earth, first looking for extraterrestrial life on these planets.
The main implication of this is that if intelligent beings exist on such planets, they are more likely to learn about the existence of life on Earth. In this way, scientists from both sides will devote themselves with greater enthusiasm to their respective "extraterrestrial life search programs" and look for each other.
Dr. Collins believes that the most likely extraterrestrial civilization is a "transiting planet" — that is, from the perspective of An Earth observer, it passes in front of its star every time it orbits.
Another big conundrum for astronomers in the search for extraterrestrial life is: Should we send signals to these planets, or should we wait to receive the signals they send? The answer given by the study is that whoever knows more about each other between these planets and Earth should be the sender of the signal; while the other side follows the rules of the game and waits to receive the signal.
Dr. Kellings explains, "We'll soon have a roster of planets that may have extraterrestrial life and know something about our world, and they might want to say something to us after they know us well enough." We should concentrate on listening to the news from these planets, and if they also understand the game strategy, they should know that we are listening. ”

The Search for Extraterrestrial Civilizations Program (SETI) is a collective term for all groups searching for extraterrestrial civilizations, not just one organization. Among the more famous academic institutions are Harvard University and the University of California, Berkeley, and the seti Association, a non-profit organization. These organizations are committed to using advanced equipment such as radio telescopes to receive electromagnetic waves from the universe and analyze regular signals from them, hoping to discover extraterrestrial civilizations.
Among them, SETI@home is a project aimed at using the idle computing power of thousands of computers connected to the Internet to search for extraterrestrial civilizations. Participants can download and run a screen saver to have their computer calculate the data fed back by the radio signal.
Frank Drake, an astronomer at Cornell University, completed the first SETI experiment in 1960.
On November 16, 1974, to celebrate the completion of the Arecibo Radio Telescope, a message called "Arecibo Message" was sent to the globular cluster M13, 25,000 light-years from Earth, in the hope of contacting aliens.
In 1977 SETI received the famous Wow! signal using the Ohio State University's Giant Ear Radio Telescope, a very strong radio signal of up to 72 seconds.
In 1984, the University of California, Berkeley officially launched the program. In 1999, it began to analyze electromagnetic waves from the universe with radio telescopes. One-third of its funding is subsidized by the National Science Foundation, one-third from the California government, and the remaining funds are met by private fundraising. Paul Allen donated $11.5 million to the program in 2001. On March 19, 2004, a further $13.5 million was donated to the program.
On April 27, 2011, Tom Pearson, director of the Institute for the Search for Extraterrestrial Intelligent Organisms, announced the suspension of the program by email informing program collaborators that the U.S. government had cut spending, which had left the program in serious short supply. On December 5, 2011, the plan was revived.
