The United States Will Build The "Sky Eye" to the Moon to Find Aliens

A Fox article today said that the world ’s largest radio telescope, the Chinese Sky Eye with a caliber of 500 meters, can be used to search for signals of extraterrestrial civilizations. As one of the symbols of modern civilization, radio signals are the signals that we can most easily be detected by distant alien life that also has a smart civilization, such as putting a smartphone on Mars, then its signal is that we can be in the sky The brightest radio signal detected. So if there is an alien world that has developed to our level, then the radio signals they emit may also be detected by us. However, like the various radio signals emitted by our earth, because the power is too small and the attenuation is fast, it is basically undetectable for 1 light year around. And the nearest star system is 4.2 light years away, so unless it is a strong radio signal sent to us by a smart civilization and received by the world's most powerful radio telescope, we will not be able to receive them. Greetings, because even then, the signal may be extremely weak when it reaches us.

Recently, NASA approved a conceptual design project that will cost US $ 125,000 to start the construction of a sky eye-radio telescope on the moon, hoping to use the moon ’s craters like China ’s Guizhou ’s tiankeng. Build a powerful telescope that can search for weak radio signals. The plan is to use the craters on the back of the moon to send robots to lay out related facilities and build telescopes. Due to the flooding of radio signals on the earth, the side of the moon facing away from us is undoubtedly the best place for us to gaze at the starry sky, which can shield all radio interference and noise from the earth, and even the radio noise from the sun at night To complete radio silence, it creates the most favorable conditions for detecting extremely weak signals.

The lunar radio telescope is not yet an official NASA project, but one of 23 innovative advanced concepts (NIAC) projects selected by NASA this year, aimed at discovering and funding the most promising projects in the next ten years or more, The total amount is 7 million US dollars, and also includes solar sails, lunar landing platform, and Titan's under-ice marine robot detector and other projects. All these detections, even other detection activities, the biggest bottleneck is the launch vehicle. The gravity of the earth is too strong. If the rocket launch can send a load of more than 100 tons into space at a time, the construction of the lunar radio telescope is not a problem at all. It can even send workers to install it. From this point of view, the Mars ship that Musk is building is indeed the key to human civilization becoming an interstellar civilization. If it succeeds in recent years, the impact on the entire civilization will undoubtedly be extremely huge, and it will also become the creation of the entire universe. The revolutionary product of history.
