Don't have gloom and hatred, at this time silence is better than sound, the two of them each looked at each other's eyes with excitement, and they didn't speak to each other, but they understood each other's meaning, and they all understood, it was a very wonderful feeling, just like the one described in the poem: the body has no colorful phoenix wings, and the heart has a little bit of a soul!

"Dad, watch TV, we seem to have discovered aliens!"

Song Zihang was flirting with Ye Xue, Ye Mengmeng, the little guy suddenly pointed to the TV and said loudly, the sound of the voice, Song Zihang and Ye Xue immediately reacted, looking at Ye Mengmeng a little speechless, this guy who single-handedly promoted the remarriage of the two of them, at this time seemed to have lost interest in this, but looked at the TV attentively, pointing at the TV and saying aliens.

Song Zihang had no choice but to look at the TV with Ye Mengmeng, only to see a news reporter wearing a suit and tie on the TV and say: "Hello audience, this is a news fast lane program." ”

News Fast Lane is a news program of Huaxia CCTV, similar to a focus interview, that is, to take out a news hotspot, and then invite a few experts to chat and talk about ideas.

And this time what they want to say is that according to a piece of information transmitted back from their frontier satellite, it seems that we have received an alien signal transmission, which is an alien language, and now scientists around the world are deciphering this alien language, hoping to master the alien language and have a dialogue with the alien.

At this time, the two astronomers were telling the history of China's aerospace, which told about the successful launch of China's first artificial satellite in Jiuquan, China, on April 24, 1970, which was of epoch-making significance and was called Dongfanghong No. 1.

Dongfanghong No. 1 is not only a surface exploration satellite, but also shoulders a very important task, exploring alien civilizations, trying to establish diplomatic relations with extraterrestrial civilizations, and on Dongfanghong No. 1, the Chinese people played a song "Dongfanghong", and said the phrase hello in Chinese.

I hoped to get an answer from the aliens, but the result was nothing, until people later discovered that there was no life in the solar system, so people wanted to pass the information out of the solar system to see if they could meet aliens in the vast universe.

However, in the process of this exploration, the great physicist and astronomer Stephen Hawking gave the world a piece of advice, that is, do not speak to the universe, because it is likely to bring disaster to mankind.

However, human curiosity did not end with the advice, but took Stephen Hawking's words as a deaf ear, so astronomers and scientists all over the world, after unremitting efforts, finally came up with an idea that could transmit sound out of the solar system and spread into the universe, and this idea was quickly implemented.

Under the arrangement of the United Nations, a team of dozens of top scientists from China, Europe, the United States, Plaster, White Bear and so on has started a vigorous external exploration stage with the support of the whole world.

At this stage, everyone thought of many ways, for example, American scientists once commanded the entire United Nations, with the strength of the whole world, to create an explorer satellite, this satellite uses a solar energy system, as long as it can receive light in flight, it can charge the satellite, and provide flight capabilities, theoretically speaking, as long as the satellite is not destroyed, it can be explored in the universe and transmit signals to the earth.

In order to cooperate with this explorer satellite, the United Nations also launched a space station into the universe with the help of the whole world, and the purpose of the space station is also very simple, that is, every other year, to send a signal expander to the outside, so as to avoid the satellite flying too far and the signal cannot be transmitted back.

Thus, after thirty years, the moon had flown out of the solar system and reached around the A centauri galaxy in Proxima Centauri.

However, this information can not satisfy the curiosity of the earthlings at all, so in the United Nations, Chinese scientists proposed a signal expansion technology, according to what the scientist said, the efficiency of non-stop exploration with a satellite is too slow, we have survived six of the world's top scientists, we have also changed from forty years old, to now in our seventies, we still have a few years to live.

And if we continue to explore like this, our grandson, grandson's grandson or grandson will not be able to see aliens, so I suggest that we should speed up, otherwise there will be too many uncertainties.

You must know that the explorer has been flying for thirty years, and then it flew out of the solar system, at this time the circuit on the explorer has been aging, and the solar panels have begun to reduce the power, if this continues, in another thirty years, the explorer is likely to be directly paralyzed, or the conversion rate of the solar panels is extremely low, and then the explorer 1 will completely lose power and become cosmic garbage.

And even if everything is normal, in another thirty years, the explorer will be able to fly out of the Centauri A system, then we will have to launch satellites, and we will have to wait for a long time, when the satellites will age again, and then become space garbage, and so on, generations, even dozens of generations will not be able to fly too far, how to find aliens, so we can't rely on physical media to explore aliens.

After listening to the words of the Chinese scientists, all the scientists were silent, and for a long time someone asked: "If we don't use satellite exploration, how can we explore?" Sound wave? ”

Acoustic exploration is a commonly used scientific detection method in the scientific community, which can accurately determine the shape and posture of things, and the more common one is what we call sonar detection.

But as soon as the scientist finished speaking, he laughed, this question is too naïve, even those who only have common sense in junior high school physics know that sound cannot be transmitted in a vacuum, and come up with the idea of measuring the universe with sound waves is simply a primary school student should put forward, and the speed of sound is only 340 m / s, the speed of the satellite has reached 7800 m / s, the speed of sound is not as fast as the speed of the satellite, then the sound detection of the universe is simply nonsense!

The scientist smiled and shook his head, and at this time, the Huaxia scientist also laughed: "It is impossible to detect the universe with sound, and this colleague is probably joking, but the idea of not using physical objects to detect is still correct." ”

"Oh, what do you think, tell me."

That's when all the scientists became interested.

"I think we can carry a huge signal diffuser, and then shout to the whole universe and transmit it in the form of radio waves!"

Chinese scientists said!
