[First of all, I'm curious, why are you willing to spend more than 400 years (converted to Earth years) to reach the edge of the Dutar black hole, spanning a distance of 4,500 light years?] 】

The question of the leader of the Dutar Star Domain Command Center was straight to the point, and there was no delay. Pen? Interesting? Pavilion wWw. ｂiquge。 Obviously, the answer to this question must be known to everyone present, and this question is just an opening sentence to get to the point.

(We must tell you frankly and unreservedly about the purpose of this trip.) I believe you must know very well that we are also a cosmic civilization with black hole science and technology as the core. At present, our scientific and technological development has encountered a bottleneck, so we deliberately came to the Dutar black hole, hoping to carry out research to find opportunities for breakthroughs. ）

As for how to make a request, the high-level of the expeditionary force had already discussed it before, and at this moment, Yuan Haochen was meticulous and clear.

[I see! 】

The leader of the Dutar Star Domain Command Center said with an expressionless face (after the previous contact with the dark energy civilization, Yuan Haochen and the others could interpret and understand the other party's expressions), but did not make a clear statement.

As a result, the entire venue suddenly became calm, and the human civilization was waiting for the reply of the dark energy civilization, but on the one hand, everyone in the dark energy civilization, including the leader of the command center, did not say a word.

(If we take the liberty of asking, can we learn more about the Dutar black hole?) ）

Yuan Haochen decided to change his perspective and euphemistically understand the significance of the Dutar black hole to the dark energy civilization, and from this, he judged that the analysis expeditionary force would have the opportunity to study the Dutar black hole.

[You should know that compared to the giant black hole in the center of the Milky Way (Sagittarius A*, about 4.5 million times the mass of the Sun), the Dutar black hole is just a small one. The leader of the command center swiped his right hand in the air, extended his gaze, and then continued, [How much strength can you control how big a black hole is, can you understand my words? 】

(Yes, we can understand that you mean that the Dutar black hole is just an entry-level black hole that is relatively easy to manipulate and exploit.) ）

Yuan knew that the Dutar black hole (Cygnus X-1) was only about 60 kilometers in diameter and only about 10 times the mass of the sun, so it could only be regarded as a "seed-level" black hole in terms of volume.

[You understand it very accurately, in fact, our dark energy civilization is still trying to completely control the giant black hole in the center of the galaxy, but it is not easy. It is foreseeable that when we are able to fully control and harness the energy of this giant black hole, we will be able to gain the ability to leave the galaxy just like the Creator civilization and its ancient super black hole civilization. The Command Center Leader continued.

(I'd like to ask you, how many natural black holes are there in the Milky Way?) ）

Yuan Haochen also guessed that the creator civilization had already controlled the super black hole of the silver heart in a distant era, and he never thought that they had left the galaxy with the huge energy of the silver heart super black hole. After listening to the other party's words, Yuan Haochen asked thoughtfully.

[It's interesting to note that we've never found a black hole of medium size in the Milky Way.] In addition to the galactic superholes, there are currently more than 200 small black holes found in the Milky Way, most of which are small wandering black holes that were born from the core collapse of massive stars when they undergo supernova explosions. The reason why the Milky Way galaxy is where it is today is that medium-sized black holes are generally born during the supernova explosion of the first generation of stars in the universe (the first generation of stars formed in the early highest-density primordial hydrogen helium cloud was relatively large), so medium-sized black holes should be mainly concentrated in the outer and outer layers of the universe. The leader of the command center continued to generously introduce to Yuan Haochen and the others, [Maybe you have also discovered that compared to the black hole located in the outer layer of the distant universe, even the super black hole with the silver heart is just a small guy. 】

(You're right, our scientific instruments have shown that there is a huge black hole at the center of almost every large galaxy, including the center of our own galaxy, at high speeds of gravity.) And we did observe a lot of truly terrifying super-black holes, including one that is 1,600 times larger (6 billion times the mass of the Sun) than the galactic-centered super-black hole. ）

Yuan Haochen knows very well that such a large super black hole, her "event horizon", that is, the boundary where any matter will never return, is even more than 5 times the orbit of Neptune. In the absence of the corresponding scientific and technological strength, human beings are absolutely unwilling to approach her.

Although our technological strength is far superior to yours, in our civilized world, small black holes like the Dutar Black Hole are the most convenient to use. Therefore, they play a very important role in our civilization system. For example, building a space tunnel is a very energy-intensive project, and at least half of the energy required for the space-time tunnel we built in the Dutar star field comes from the Dutar black hole. 】

(I see, the Dutar black hole is an important source of energy for you!) ）

Yuan Haochen knows that human civilization now lacks not only a natural giant energy source like the Dutar black hole, but also lacks a safe, reliable, and scientific and technological technology that fully and extensively uses the energy of the black hole. And these are the purposes of his expeditionary force.

It is conceivable that if human civilization also has a natural black hole, then it can make full use of its huge energy to serve the civilization's scientific and technological system, and use the energy of the black hole to build a space-time tunnel and carry out more distant interstellar travel.

So, do you know the significance of the Dutar black hole to us? The leader of the Dutar Star Domain Command Center asked meaningfully.

(Yes, we've been clear, thanks for your advice.) Yuan Haochen thought for a moment, and then asked, (Dear leader, I just heard that when you were building the space tunnel, half of your energy came from the Dutar Black Hole, so where did the other half of the energy come from?) ）

[Nature is still a black hole, a consumable artificial black hole with enough mass and energy. The leader of the Dutar Star Domain Command Center replied without thinking, [On the one hand, the black hole can be a source of energy for shuttles, and on the other hand, her powerful gravitational effect is the key to distort time and space and connect the two points in space. 】

After listening, Yuan Haochen couldn't help but sigh in his heart: "TMD, this is another technology that human civilization lacks. ”

So he said: (I see, if we want to create a large enough artificial black hole, human civilization still has a long, long way to go.) ）

In fact, the subtext of this sentence is to euphemistically express the vision of human civilization, hoping to get the scientific and technological guidance of dark energy civilization.

Yuan Haochen, Don Quixote and the others believed that these high-ranking people in the Dutar Star Domain on the other side would definitely understand the meaning, but it was still a question whether they were willing to help generously......
