Does the United States have the right to let Voyager carry the information of all mankind and the position of the earth into the universe?
The last time NASA had good contact with Voyager was on 20 17 1654381October 28th. After nearly 20 hours of signal transmission, NASA engineers successfully woke Voyager 1 which had been sleeping for 37 years for the first time, and started four standby orbit correction thrusters, with perfect results. This is the first time that humans have successfully commanded such a long-distance aircraft from a distance. This precise positioning and deep space network transmission technology is really amazing. After this fine-tuning attitude, Voyager 1 has let itself fly.
In fact, the solar system exploration mission has been completed. The probes flying out of the solar system are not Voyager 1, but also pioneers 10,1and Voyager 2, which were launched earlier and later.
These detectors all carry information about human beings and the earth, and they fly in different directions in space, which means that these information will be sent to all directions in space. So don't worry at all.
As early as the 1970s, humans sent earth information into space. 1974 165438+1016, scientists aimed at the Perseus globular cluster for three minutes with a 305-meter radio telescope in Arecibo, Puerto Rico, and launched the first "earth telegram" sent by human beings to extraterrestrial civilization into outer space.
It has always been urgent to find extraterrestrial civilization, because if there are only humans in the universe, it will be too lonely.
The scientific community has been using the most advanced equipment and technology to scan and search space for decades, and has emitted countless radio signals.
Now the transmission of these signals has reached dozens of light years away, covering a very wide area. If extraterrestrial civilization can receive or discover humans, it should first discover these signals, not human spacecraft that have not yet flown out of the solar system.
The human spacecraft has been flying for more than forty years, and it is far from flying out of the solar system, so the probability of encountering extraterrestrial civilization is very small.
Now the scientific community generally believes that the solar system should be bounded by the gravitational radius of the sun, which is about 1 light-year.
It will take Voyager 1 7000 years to fly out of this range at the current speed. Therefore, it is absurd for some mysterious aliens to imagine that aliens will invade the earth every day and pour dirty water on this great human messenger.
If extraterrestrial civilization is much higher than earth civilization, what do they need from the earth? Their ability to bring people to earth can make full use of the energy of a star.
In the vast universe, the earth is not even a grain of dust. Is it so tempting to invite people from outside Wen Mingzhen?
Therefore, although space-time communication appreciates the whimsy of Three-body and Liu's magnificent description of the future, it does not agree with the so-called "dark forest law" when it comes to life.
