Waves?!!

Hearing this, all the scientists were stunned, and they all frowned.

Radio waves, also known as electromagnetic waves, have a speed close to the speed of light and are the only efficient means of transmission that humans can currently master, and their speed is much faster than the so-called sound waves, as well as the speed of satellites.

According to scientific calculations, the speed of electromagnetic wave C is about equal to the speed of light 3x10 to the 8th power of m/s, which is a speed that human beings dare not imagine, almost one day can rush out of the solar system, two days can penetrate the Centauri A galaxy, as long as the diffuser is large enough, this electronic signal can be diffused into the universe, where human imagination is unimaginable

As soon as this proposal was put forward, the Chinese scientist immediately attracted the attention of all scientists, and then the Chinese scientist said: "The vastness of the universe is definitely beyond the phenomenon of our human beings, and human beings are not even ants in front of the universe, at most they are some relatively intelligent parasites, and the distance between galaxies and galaxies in the universe is often a few light years, dozens of light years, hundreds of light years." ”

"And it took nearly thirty years for our satellite to come out of a solar system, not to mention running a distance of a few light years to another big galaxy, if we only use the current speed, we may not be able to walk a distance of one light year in a thousand years, so let alone us, I am afraid that our children and grandchildren may not be able to see a single alien."

"But if we use radio waves to explore the universe, it is different, radio waves have the same speed as light, and it only takes a year to walk alone, so wouldn't it be possible to quickly allow us to reach farther cosmic space?"

As soon as the Chinese scientist finished speaking, a scientist said: "First of all, I assume that we can send radio signals to the universe through your ideas, but there are two questions, the first question is how to determine where the signal is being sent and to whom, there is no scientific value without tracking, and the second is how to ensure that aliens can receive our signals, what if aliens can't receive our signals?" ”

The scientist's question was very sharp, and then the Chinese scientist said: "First of all, the first question, our radio waves are randomly emitted to the universe, as for where they are transmitted, I don't know, and we don't need to know, because once an alien receives a signal, it is likely to be sent back to us, and then we can rely on the feedback signal to determine the location of the other planet and the distance from the earth." ”

"Second, as for what to do if the aliens can't receive our signal, the first can't receive our radio signal, which means that their technology is not as developed as the earth, so it loses its scientific value, after all, if this radio signal is transmitted a few light years away, and the life planet is discovered, even if the life planet is not at a high level of technology, we can't mine that planet, or immigrate to any means, after all, the distance is too far, and our technology can't take us that far."

"Of course, if the other party's technology can receive our radio wave signals, if it is relatively equal to our scientific and technological development, then they can send us radio waves to reply, if the other party's technology surpasses us, we can even communicate with these technologies well, which will be of great help to the scientific and technological development of our earth, and help us enter the 2.0 level civilization in advance."

After the Huaxia scientist said this, everyone was silent, to be honest, the proposal of radio waves was still very reasonable, but after half a day, a scientist spoke: "Okay, even if what you said makes sense, then I will ask you a specific question, how do we put radio waves into the universe, you must know that it is good that the radio waves of the earth itself can radiate to the edge of the solar system, and it is impossible to transmit them to a distance too far......"

"So we need an amplifier!"

Before the scientist finished speaking, the Huaxia scientist had already interrupted the scientist and said, "I wonder if you have ever heard of stellar power amplification technology?" ”

"Huh?"

As soon as these words were finished, all the scientists were stunned, and then the Chinese scientists smiled and said: "This discovery is discovered and named by the latest Chinese scientist Liu Xin, Professor Liu Xin has experienced countless failures in countless experiments, and it took ten years to make a great scientific and technological achievement." ”

"What the hell is it? Are you talking so good? ”

A scientist frowned and asked, at this time the Huaxia scientist said: "Professor Liu Xin found that when we send radio waves to the sun at a specific frequency, after reaching a certain power, we can trigger the sun to accurately radiate the information with greater power, so as to send the radio waves to the universe, although this method has a certain degree of uncertainty and uncontrollability, but it is not very important for us at this stage, after all, our purpose is to send the signal out, and we are not sure to shoot the signal to the constellation Centauri. It's still other constellations next to us, so it doesn't matter where this radio wave flies! ”

As soon as the Huaxia scientists said this, everyone present was stunned, if according to the idea of the Huaxia scientists, this method is feasible, and the current science and technology are enough to do this, but at this most critical time, all the scientists suddenly fell silent, and their expressions became serious.

In the end, all the scientists looked at the Chinese scientists, a British scientist, and said: "It is true that exploring the universe is attractive enough for us, and if it succeeds, it will be enough to change the development process of earth science and technology, but everyone should not forget Mr. Hawking's advice." ”

Stephen Hawking, the founder of modern cosmology, his "A Brief History of Time" and "The Universe in the Shell" are the foundations of modern cosmic science popularization, his understanding of the universe is far beyond that of ordinary scientists, he once said, don't speak to aliens at will, because you never know whether you attract demons or angels, hope or destruction.

At this moment, all the scientists were silent, they didn't know whether they should make a voice to the universe, and they didn't know how long it was, a scientist from a plaster country raised his hand and said: "Don't be too pessimistic, maybe, maybe we are not ushering in demons, but angels, at that time, the earth's science and technology will be developing wildly day by day, and we will bring unprecedented hope to the earth!" ”

As soon as the scientists of this plaster country spoke, they resonated with all the scientists, in fact, they didn't know that it was dangerous to do so, but curiosity kills cats, and scientists are often the most curious people, so after thinking twice, they finally sent an airwave message to the universe.

"Hello, aliens!"
