Chapter 299 Electromagnetic Wave Signal

Of course, you can't see through it, after all, Yue Yuan doesn't have super powers.

There's nothing big about coming and going. Since Manyuemei is here, Yue Yuan simply stopped paying attention to the porthole and chatted with her. They were all some meaningless topics, but it was quite pleasant.

Perhaps because he has been in a high position for a long time, except for some senior scientists in the new government, other people always hesitate when talking to Yue Yuan. Yue Yuan naturally noticed this, but he couldn't do anything about it.

Of course, Manyuemei is different. She didn't make Yue Yuan feel that way. Instead, she was too casual. Well, this happens when it's not a work topic.

In fact, hundreds of years ago, when Manyuemei showed some of her feelings because of the life potion incident, Yue Yuan felt it. He is not stupid, so he naturally knows what this woman means.

But just as he was entangled back then, this matter is really difficult to deal with. Yue Yuan didn't say this clearly, but the two have worked together for hundreds of years, and Manyuemei probably saw it.

The two chatted tacitly, but this time their chat didn't last long before a message interrupted them.

It was a message from the military.

Unlike previous communication reports, this time the information was directly transmitted to Yue Yuan through the human internal communication network.

If it can be directly transmitted to Yue Yuan, the matter must be not simple, and there is a high probability that the detector has discovered something.

The current new government system is much more perfect than before. For example, for messages outside of human civilization, it is no longer necessary to send them to the Tianqin Command Center first, and then the command center will notify Yue Yuan and let him rush to the command center, but both at the same time.

As one of the deputy commanders, when Yue Yuan received the message, Manyuemei also received the message.

The two looked at each other, without saying much, and directly opened the personal terminal to check the content of the message.

Sure enough, the detector found a signal. After taking a look at the personal terminal, Yue Yuan knew what was going on.

"Let's go and take a look." Then, Yue Yuan greeted Manyuemei next to him, and then turned to the command center.

The information sent by the communication department shows that the detector should have detected an electromagnetic wave signal with obvious patterns.

The content of the electromagnetic wave is still unknown, because the detector far away from one light year cannot know how to decipher it by itself. It just received the signal and then forwarded it to the human fleet behind according to the established procedures.

Deciphering and analyzing work, human scientists have to do it themselves.

"This is another troublesome thing. It seems that I really have to go back to the Second Fleet as soon as possible." Man Yuemei nodded, then turned off the magnetic boots, kicked her right foot slightly, and floated to the command center with Yue Yuan.

"The specific content will have to wait until the scientists decipher the signal, but it must not be a good thing. It's right for you to go back to the Second Fleet as soon as possible, but there is no rush. Go back tomorrow." Yue Yuan turned his head and said.

The detector received the signal from a light-year away. It takes a year for the signal to be transmitted at the speed of light at a distance of one light-year. The human fleet has plenty of room for operation. Moreover, the Second Fleet does not need to wait for Man Yuemei to arrive before it can take action. If there is really an emergency, just send an order from Tianqin and let the on-duty personnel execute it first.

In fact, there are two other reasons why Yue Yuan is so calm. One is that it is not the first time he has encountered aliens. He is no longer as surprised as before. The second is the form of the signal.

When browsing the information just now, he has noticed that the signal source received by the detector is indeed in the form of a signal. From this point, it can be preliminarily judged that the technological level of the signal source is not very high.

Because as far as humans know, the communication and information transmission method of the second-level civilization layer can be replaced by neutrino communication. Of course, neutrino communication cannot transmit information to unknown targets in the form of broadcasting. After all, there are only two types of waves that can transmit information in the universe, one is electromagnetic waves and the other is gravitational waves.

Both of them are caused by long-range forces, so they can transmit information in space.

So if the information source has a high level of technology, the detector should receive gravitational wave signals in addition to electromagnetic wave signals.

But now there are only electromagnetic wave signals, which is enough to show that the information source does not have the technology to emit gravitational waves.

Therefore, even if an alien civilization is encountered, the level of civilization should not be too outrageous.

Of course, this judgment is definitely one-sided. After all, humans themselves do not know what level of civilization they have to reach to be able to create and emit gravitational wave signals.

Anyway, humans can't do it, and maybe even level 3 civilizations may not be able to do it.

It's true that humans can use laser interferometer space antenna arrays to receive gravitational wave signals, but the technology gap between receiving and emitting is more than just a gap, it is simply countless technical barriers.

And if you want to judge the level of civilization of the signal source, you can only wait.

One is to wait for the follow-up information sent back by the detector, and the other is to wait for scientists to decipher the content of this electromagnetic wave signal and then analyze it.

But no matter what the result is, humans must start to prepare for it.

So when drifting towards the command center, Yue Yuan asked Manyuemei to talk to the second fleet's duty officer first, so that he could be mentally prepared.

After drifting for a while, the two arrived at the Tianqin's command center.

As soon as his feet landed, Yue Yuan asked the scientific officer who was busy at his post: "Has the follow-up information from the detector been transmitted? What's the situation? Has the detector captured the source of the information?"

Human civilization does not know much about the universe at present, but the staff on the warship are no longer the white novices of the past. Basically, they all have a certain understanding of the universe. As the scientific officer of Tianqin, he naturally knew why Yue Yuan asked such a question.

The universe is vast and boundless, and the starry sky is deep and dark. Even if intelligent life has embarked on the starry road with technology, it is not easy to see what is on the other side of the starry sky.

Therefore, even if an unknown civilization discovers human detectors, it is impossible to find the human fleet at the first time in a distant light year away. After all, the space where the human fleet is located does not have any dense interstellar dust clouds.

As for the follow-up information of the detector in the question, of course, it is because the universe is too vast.

Since the few small detectors of human beings can be discovered, it must be that the distance between the two is too close. Even so, human detectors can definitely find the target, unless the technological gap between the two sides is too large.

If that were the case, Yue Yuan would definitely order the fleet to change course without hesitation.
