Electromagnetic Wave Signal
It's impossible to see through him, since Yue Yuan doesn't have superpowers.
Nothing much happened during their visit. Since Man Yuemei had arrived, Yue Yuan simply stopped paying attention to what was happening outside the porthole and started chatting with her about trivial matters, which was quite pleasant.
Perhaps because they had been in high positions for a long time, apart from some senior scientists, most people in the New Government were hesitant and timid when speaking to Yue Yuan. Yue Yuan naturally noticed this, but there was nothing he could do about it.
Of course, Man Yuemei was different. She didn't give Yue Yuan that feeling. On the contrary, she was too casual. Well, that's how she was when it wasn't about work.
In fact, Yue Yuan had sensed it hundreds of years ago when Man Yuemei revealed some of her true feelings because of the Life Elixir incident. He wasn't stupid; he naturally knew what this woman meant.
However, just as he had struggled with back then, this matter was indeed difficult to handle. Yue Yuan didn't say this explicitly, but having worked and interacted with him for hundreds of years, Man Yuemei probably understood as well.
The two chatted tacitly for a while, but this time their conversation was interrupted by a message.
It was a message from the military.
Unlike previous communication reports, this time the information was transmitted directly to Yue Yuan through the human internal communication network.
If something can be transmitted directly to Yue Yuan, it must be something significant; it's highly likely that the detector has discovered something.
The New Government's system is much more sophisticated than before. For example, messages from outside the realm of civilization no longer need to be sent to the Lyra Command Center first, and then the Command Center needs to notify Yue Yuan so that he can rush to the Command Center. Instead, both can be sent simultaneously.
As one of the deputy commanders, Man Yuemei received the news at the same time as Yue Yuan.
The two exchanged a glance, said nothing more, and immediately opened their Personal Terminal to check the message content.
Sure enough, the detector detected a signal. After glancing at his Personal Terminal, Yue Yuan knew what was going on.
"Let's go take a look." Yue Yuan then called out to Man Yuemei beside him, and then turned and headed towards the Command Center.
The information transmitted from the Communication Department indicated that the detector had detected an Electromagnetic Wave signal with a clear pattern.
The content of the Electromagnetic Wave is currently unknown, because a detector a light-year away cannot possibly decipher them on its own. It simply receives the signal and then, according to a predetermined procedure, relays it to the human fleet behind it.
Deciphering and analyzing the code is something that human scientists have to do themselves.
"This is trouble again. It seems I really need to get back to the Second Fleet soon." Man Yuemei nodded, then turned off the Magnetic Boots, pushed off slightly with her right foot, and floated towards the Command Center with Yue Yuan.
"We'll have to wait for the scientists to decipher the signal to find out the specifics, but it probably won't be anything good. It's right for you to go back to the Second Fleet, but there's no rush. Go back tomorrow," Yue Yuan said, turning his head.
The detector received the signal from one light-year away. It would take a year for a signal to travel at the speed of light to travel that distance. The human fleet has plenty of room to maneuver. Moreover, the Second Fleet does not necessarily have to wait until the Man Yuemei arrives before it can take action. If there is any emergency, an order can be sent from the Lyra to the personnel on duty to carry it out first.
In fact, there are two other reasons why Yue Yuan is so calm. First, it's not the first time he's encountered aliens, so he's no longer as easily startled as before. Second, it's about the form of the signal.
While browsing the information, he noticed that the signal source received by the detector was indeed in signal form. From this, he could preliminarily judge that the technology of the signal source was not very advanced.
As far as humanity knows, communication and information transmission at the Level 2 Civilization stage can already be replaced by Neutrino Communication. Of course, Neutrino Communication cannot transmit information to unknown targets in a broadcast manner, since only two types of waves can transmit information in outer space: Electromagnetic Wave waves and Gravitational Wave.
Both of these are caused by long-range forces, and therefore can transmit information in space.
Therefore, if the information source is technologically advanced, the detector should receive Gravitational Wave signals in addition to Electromagnetic Wave signals.
However, the fact that only Electromagnetic Wave signals are currently being used indicates that the source of the information has not mastered the technology to transmit Gravitational Wave.
Therefore, even if they encountered Alien Civilization, its level of civilization should not be too far off.
Of course, this judgment is certainly one-sided, since humanity itself does not know what level of civilization it would take to be able to generate and emit Gravitational Wave signals.
Humans simply can't do it, and perhaps even Level 3 Civilization might not be able to.
It's true that humans can use Laser Interferometer Space Antenna arrays to receive Gravitational Wave signals, but the difference between receiving and transmitting is more than just a chasm; it's countless Technology Barrier.
To determine the level of the civilization from which the signal originates, we can only wait.
First, we need to wait for the detector to send back follow-up information; second, we need to wait for scientists to decipher the content of this Electromagnetic Wave signal and then analyze it.
Regardless of the outcome, humanity must begin preparing for a response.
So, as they drifted toward the Command Center, Yue Yuan had Man Yuemei speak to the officer on duty of the Second Fleet beforehand, so that he could prepare himself mentally.
The two floated for a short while before arriving at the Command Center of the Lyra.
As soon as his feet touched the ground, Yue Yuan asked the Science Officer, who was busy at his post, in a three-part question, "Has the probe transmitted any follow-up information? What's the situation? Has the probe detected the source of the information?"
Human Civilization's current understanding of the universe is indeed limited, but the crew members on the warship are no longer the novices they once were; they generally have some knowledge of outer space. As the Science Officer of the Lyra, he naturally knew why Yue Yuan asked that question.
The universe is vast and boundless, and the starry sky is deep and dark. Even though Sentient Life has embarked on its journey to the Starry Road through technology, it cannot easily perceive the things the Other Side of the Starry Sky.
Therefore, even if Unknown Civilization discovers human probes, it is impossible for them to detect the human fleet from a distance of one light-year, since there is no dense Interstellar Dust cloud in the space where the human fleet is located.
As for the follow-up information about the probe in the question, it is of course because the universe is too vast.
Since those few small human probes were able to detect the target, it must mean that the two sides were too close. Even so, human probes should have been able to detect the target, unless the technological gap between the two sides is too great.
If that were the case, Yue Yuan would definitely order the fleet to change course without hesitation.
