Mystery code
According to media reports: NASA is planning to launch a new mysterious code, intending to contact extraterrestrial civilizations, while British scientists believe that this is playing with fire, and the purpose of doing so is likely to accelerate the extinction of human civilization and even life on earth.
Fancy ostentation
As we all know, the United States can be said to be the most powerful country in the world today, whether it is military strength or economic strength, far beyond other countries, of course, for the United States, as the world's strongest country, need to show its strength to others, and the earth, it seems that they can no longer tolerate their expansion, they want to show their so-called "technology" to extraterrestrial civilizations.
Wish for the moon
Professor Stephen Hawking once said: The earth where we humans live is just a remote corner in the vast universe, the universe has a history of nearly 13.8 billion years, and the first batch of stars were born 13.7 billion years later, which means that at that stage, after the stars are born, planets appear.
The observation of the distant sky through contemporary astronomical telescopes also confirms that there are countless galaxies in the universe, and the Milky Way we are in is just a drop in the ocean. Of course, leaving aside the universe, there are nearly 400 billion stars in the Milky Way galaxy where we live, and each star has planets and moons.
The vastness of the universe
Not only that, with the development of science and technology, human scientists have discovered a lot of terrestrial planets and similar star systems like the solar system, and the discovery of these star systems not only fills the gap in human exploration of terrestrial planets, but also lets us know that human beings are not alone.
In fact, whether there is an alien civilization in the universe, there have always been two theories, one is there, the other is not, there is, because the universe is too big, its history is too long, and the content of matter contained on the earth, for the vast universe, is not worth mentioning, then in such a remote corner of the earth, can give birth to the existence of life, then in other places, there will definitely be civilizations.
Extraterrestrial civilizations
It is worth mentioning that the emergence of these civilizations is earlier than that of humans on Earth, so their technology is also more developed. It also means that once they have the ability to come to Earth, it can be proved that they did not come to make friends with us, but to invade nakedly. Scientists have long opposed this attempt to connect with extraterrestrial civilizations.
In fact, long before this, the United States has repeatedly communicated with extraterrestrial civilizations in outer space by transmitting radios. For example, the decommissioned Arecibo Radio Telescope, before that, had sent mysterious codes to outer space, which were transmitted to distant universes, waiting for the day when an alien civilization would receive them.
"Mystery Code"
Is it possible to know everything on Earth with just one piece of code? Indeed, because the code sent by NASA not only has information about the position of the solar system, but also the distribution of elements composed of life on Earth, as well as human characteristics and human science and technology at present.
Of course, if the alien civilization captures these signals, they may not be able to analyze the current science and technology of human beings, but as life, they must know some of the information, such as the elements of life on earth, such as the position of the solar system, etc., and then combined with the unique characteristics of the solar system, the alien civilization can easily find our location.
Receive the signal
But we don't have to worry, because even if radio travels through the universe at the speed of light, it is still very slow, and if the transmitted signal reaches an extraterrestrial civilization hundreds of thousands of light-years away, then they will receive the signal hundreds of thousands of years later.
If they were to invade Earth, it would take hundreds of thousands of years, and by that time, human civilization might be long gone in the solar system. Of course, if it is a close civilization, the consequences will be tragic.
This article summarizes
For example, if we send a signal to Proxima B, which is 4.2 light-years away from Earth, the signal will get there in more than 4 years, and then they will receive, and that is 8 years from Proxima Centauri to Earth.
As in the science fiction novel "The Three-Body Problem", once these civilizations arrive on Earth, the results can be imagined. In this regard, do you think that human beings should send information to the universe to contact extraterrestrial civilizations?
