The next person to report to Hara was Tesla, the commander of the engineering and construction department. Pen "Fun" Pavilion www.biquge.info

Since Tesla's department is not directly responsible for specific tasks, and most of them cooperate with collaborative work, his report is much simpler than others.

After the debriefing, Tesla sat down in his seat a little shyly. Yuan Haochen knew his character, so he motioned for him to sit for a while: "Tesla, don't worry, I still have a few questions for you." ”

"Well, you can ask." Tesla was stunned for a moment, and then quickly replied.

"Don't be nervous, it's all about your area of expertise." Yuan Haochen smiled and said to Tesla in a relaxed tone.

"Okay." As soon as he heard that it was a question involving his field of expertise, Tesla immediately felt much more relaxed.

"Do you have any thoughts on the interstellar communication requests from ......the New World that have been going on for hundreds of years?" Yuan Haochen immediately began to ask.

"This ....... Tesla hesitated for a moment, then asked rhetorically, "Leader, I understand what you mean, you are questioning the purpose of their signal." ”

"Not bad." Yuan Haochen nodded indifferently and replied.

Indeed, all previous mainstream research has assumed that those who sent communication requests in the direction of the Milky Way 210 years ago were motivated to get in touch with the Milky Way's human base camp in order to ask for help. However, I think this idea is unrealistic...... Tesla replied with some apprehension.

"Then why didn't you question it in the previous discussions?" Yuan Haochen asked.

"This ...... Tesla squirmed, "I didn't think that point of view was important as a whole. ”

"But, you understand it now."

"Yes, I'm already aware of it."

"Okay, then you can analyze it for me from a technical point of view."

"First of all, the New World and the Milky Way are more than 4 million light-years apart, and even if we have the most powerful directive transmitting stations at their peak, and whether it is gravitational waves, electromagnetic waves, or lasers and other means of communication, it is not enough to meet the communication requirements of such ultra-long distances." Tesla said very firmly.

"Well, that's my original point of view, so I'm asking you if there are any other ways to achieve this communication requirement in the field of engineering operations and implementation." Yuan Haochen also knew very well that it was a distance of 4 million light years, and when the signal arrived in the Milky Way, it would decay and disperse into something.

In response to Yuan Haochen's question, Tesla pondered for a long time before answering: "Or, this is only a theoretical possibility." A strong gravitational wave communication device based on medium-sized black holes ...... ”

Compared with other means of communication, gravitational wave communication can easily penetrate objects without obvious decay. Because of this, the communication function of gravitational waves is widely used in the field of ultra-long-distance communication in astronautics.

However, how to generate gravitational waves of sufficient intensity is the biggest technical problem in the communication process. In fact, even if the mass of an entire star were used to create gravitational waves, it would be tiny.

Human civilization has always used the powerful gravitational effect of artificial small black holes to solve this problem, and because of its practical utility, it has not been used as a conventional means of communication.

"Black holes above medium!!" Yuan Haochen's eyes lit up, and he shook his head and continued, "That's impossible, you must know that even the Dutar black hole mastered by the base camp of human civilization in the galaxy can't reach the standard of a medium-sized black hole!" ”

"Yes, that's why I said it's only a theoretical possibility." Tesla replied in a low voice.

There was silence in the office, and Hara leaned back slightly until her back rested on the soft back of her chair.

Tesla also sat quietly in his position, looking at the leader from time to time with the corner of his eye, silently waiting.

This time, Yuan Haochen pondered for more than 10 minutes before finally speaking.

"Not to mention more than 200 years ago, even 2,000 years ago, it would be impossible for the New World to have a medium-sized black hole."

"Well, no one in the New World has the ability to make contact with the galaxy." Tesla then added, "I'm referring to the category of human civilization. ”

Yuan Haochen understands that Tesla means that the source of the signal may not be in the New World, and it may not be sent by humans (such as the dark energy civilization). However, these are beyond the scope of discussion for the time being.

"So, we can infer that the destinations of those who sent communication requests from the New World 210 years ago are debatable, and perhaps they are not the human base of the galaxy, but just a coincidence of direction?"

"Or maybe they don't know the communication doesn't work?"

"Or do they insist on trying even though they know it's slim?"

Yuan Haochen picked up the tea on the table and took a few sips, but he didn't come up with a clear idea.

"What do you think?" Yuan Haochen suddenly turned his head and asked Tesla opposite.

"These, perhaps, are possible. It's been so long after all...... Tesla didn't make a decision, so he replied softly.

"After you go back, organize people to continue to study the possibility of getting in touch with the galaxy, which will be of great help to Yu Liang and them in their search for a target." Yuan Haochen nodded slightly, and then admonished.

"Okay, we'll be mindful."

"It's hard work, you go get busy first."

After Tesla left, Yuan Haochen was still thinking alone in the office.

Who exactly is it? What is their purpose, and what are they sending in the direction of the Milky Way?

......

"Feihong, from today onwards, you must make tracing the source of the communication signal the most important job of our military, there is no one!!"

With a hint of anger on his face, Yu Liang shouted an order to Commander Yu Feihong, who was standing opposite him.

"Yes!" Although the military had already made tracing the source of the communication signal the most important task, Yu Feihong did not say much, because he could feel Yu Liang's pressure.

"I let go of everyone at the conference, but now I haven't made any achievements!"

Every time Yu Liang thought of the embarrassing scene when he reported to the leader, he felt that he had no place to be ashamed and lost face.

"The leader has given us full authority for this task, and he also requires us to use all military resources and find out the answer as soon as possible." Yu Liang turned his back and looked out the window with a solemn expression, "As long as these people or organizations that sent messages still exist, or as long as they once existed in the territory of the New World, we must quickly find them out!" ”

"Yes, in the next few days, I will personally interrogate the search efforts of all the legions, and if there are no more clues, I will not have the face to meet you." Yu Feihong bowed and promised Yu Liang loudly.

Hearing this, Yu Liang's expression eased and said, "That's not good, if you don't come back, who will help me resist these pressures?" ”
