Di Di Di ......

Jiqing turned around, and instead lay on his side and curled up on his small bed, his mind was chaotic, and after a while, a thought flashed in his heart, growing bigger and bigger, driving away the chaos around him.

Alas......

Jiqing's brain began to work, but he didn't want to open his eyes, and a helpless thought lingered, and it was that strange dream again.

Spare me! Jiqing curled up in a ball and groaned in pain.

I don't know when it began, Jiqing always entered a strange dream in his sleep, this dream was very illusory, not real at all, just like the advertisement imposed in the movie, which made him very uncomfortable, but helpless, because this dream was not under his control at all.

At first, he did not pay attention to this dream, and like any other dream, it was quickly forgotten, but as it was repeated again and again, and after a certain number of times, he knew that he was asleep whenever he entered the dream. At first, he struggled to wake up by all means, but the more he struggled, it was useless except to destroy his emotions, but it made him even more tired when he woke up after a long time.

Slowly, he began to accept this helpless reality, the generation of this dream will not easily dissipate, he began to carefully experience the scenery and feelings in the dream, and wanted to find the reason for the appearance of the dream.

After several careful experiences and searches, he found that everything in this dream was so strange that he could be sure that he had never seen anything there.

After the dream ended, Jiqing returned to his own spiritual world and continued to sleep, or entered another dream until he himself was awakened by the sound of a timer......

Di Di Di ......

Got it, got it! He reached out and waved it in the air, and the timer stopped ringing.

After a while, he slowly and leisurely swiped a few times on the controller beside him, the bed under him slowly tilted an angle, and the bed surface also changed a curved shape, making his originally stiff body much more comfortable, he reached out and rubbed his eyes, reluctantly opened them, and saw Hachi, who was sitting leisurely on the side in front of him, turning his hand in the air.

Can't you turn off the timer for me? You should think it's noisy too!

"Me? ......" Hachi snorted, "It's okay, it doesn't seem to have anything to do with me." ”

"You're my assistant, okay? You should help me solve all kinds of problems in a timely manner...... For example, the moment the timer goes off, I turn it off in time to ensure my sleep. ”

"I'm an assistant, not a nanny, and I'm going to close it myself." Hachi looked carefully at the virtual screen in front of him, and his attention didn't turn elsewhere at all.

"What are you looking at? So seriously? Jiqing asked strangely, curiosity was aroused, so that his mind was concentrated, and he was ready to get up and take a look, but as soon as he exerted his whole body, he put his lazy body back on the bed, and continued to stare at Hachi with his eyes.

"Yesterday's analysis report of the secondary alert. Your heart is also really big, from yesterday to now, almost everyone is staring at the information released by the General Staff, but you can sleep, judging from the monitoring indicators, your sleep quality is almost the same as usual. ”

"Would you like to come and have a look?"

Hachi felt Jiqing's waking up action, turned his head and gave him a roll of his eyes, this expression Jiqing is very familiar, since he found it out from the earth's original database, and showed it to Hachi with great interest, this expression will be used on himself countless times in the following time, which really made him unexpected.

"I have to sit for a while, and then I get up immediately after sleeping, and my blood pressure will suddenly rise, which is not good for my heart and cerebrovascular system." Jiqing replied with a smile, Xiaoba didn't answer his words, but just made a simple operation with his hand, and waved his hand to unfold the virtual reality screen in front of Jiqing. The report is very long, and there are a lot of graphics and text, but Hachi has clearly marked the important information.

"The preliminary judgment of the scientific research department yesterday was basically correct, according to the analysis of the detected gravitational data, there is indeed a gravitational field similar to that caused by a massive celestial body in our vicinity, and this gravitational field is enough to cause gravitational wind anomalies."

"Ao, it's not unusual, there shouldn't be any other reason for the gravitational wind anomaly except for massive celestial bodies, right?" Ji Qing said casually, and then suddenly understood something, "It's not right, even if the gravitational wind anomaly occurred after contacting the Vanguard Fleet, but with the current detection means, it is impossible for the Radar Detection Department to miss such important information before formulating this plan." ”

"It is impossible to miss a normal celestial body, but if the relative motion of this celestial body is very fast, it is possible that it would have been outside our detection range, and suddenly arrived in this area before the contact between the gravitational wind and the gravitational wind, and stirred the originally stable gravitational wind, causing an anomaly."

"Also, this celestial body is really an uninvited guest, there are really any coincidences in the universe, and the originally perfect plan will become so unusual because of a small accident." Jiqing sighed that this time it was originally a simple task to encounter the gravitational wind in Kuafu, but the universe actually gave Kuafu another "surprise".

It has been proven for a long time that the cosmic space between the stars is not as empty as humans have observed on Earth, but because these celestial bodies do not emit light or heat, etc., humans cannot simply observe them. In fact, even if it is a planet that is shining around a star, there is no way for humans to easily distinguish it, after all, the distance is too far, and human observation of cosmic celestial bodies is still based on light and shadow. The means by which human beings discover these hidden "shadowy" celestial bodies are generally calculated by the observed laws of the movement of celestial bodies based on the theories they have mastered. However, the results of this calculation are also very vague, and it is not possible to accurately determine the mass and morphology of these celestial bodies, and second, it is impossible to determine their exact position.

"But it's also a kind of luck to think about it, if this celestial body hits Kuafu directly, even if it just passes by, Kuafu can't afford it." Jiqing's overly optimistic personality was revealed, and it flipped down, "Why is the report so long?" ”

"Because what was just said is only a small part of the report." Hachi explained, "This imaginary celestial body mysteriously disappeared after disturbing the gravitational wind, and except for the gravitational field captured by the probe, the radar department has not found even a trace of it so far, not even a small fragment. ”

"Didn't the gravitational vortex hurt it? Could it be that this celestial body is the outside? Neutron star? Miniature black holes? ”

"There is no accurate judgment in the report, and since no celestial objects have been found to trigger this gravitational field, several other possibilities have also been included in the report, although coincidental, but theoretically exist. The first is the gravitational wind cancellation theory. We know that gravitational winds also have their own unique characteristics and scopes, and if two or more gravitational winds meet, will they cancel each other out or enhance each other. This is also divided into several cases, two gravitational winds that are almost parallel to each other propagating in the same direction, and within the range of their continuous coincidence, the gravitational wind pattern will not change. There is also the case that a gravitational wind happened to meet with it before we encountered it, and caused an anomaly. Of course, none of these speculations have been confirmed, and we have no ability to study this unexpected situation again. ”

"These people in the scientific research department have really worked hard!" Jiqing was really a bit eye-opening, and he admired the people who conceived these bold guesses.

"Someone is asleep, and it doesn't make a difference to everyone." Hachi's breath was full of disdain.

"I ...... My job is to do my job...... To complete my job well, I must have sufficient energy, and sufficient energy needs to rest well, which is a responsible work attitude. Jiqing naturally can't easily accept this kind of comment on himself, and there is almost no time to think about a set of rhetoric, "Other things are naturally done by someone, division of labor, you know?" In modern society, only the division of labor can be efficient. If I can go to the research department, I can work on these things all night. ”

"Okay, now I'll give you some time, you can think about what the reason for this mutation is, don't be afraid of being outrageous, I'll see if you can squeeze a little out of your head."

"That, that ......" Jiqing quickly flipped through the information in his head, and his habit of flipping through the old Kuafu database in his leisure time really helped him at this time, "There may be a time and space fault!" Or a rift in space. ”

"......" Hearing Jiqing's speculation, Xiao Ba paused for a while, not knowing what his logic system was analyzing.

Ji Qing also unconsciously said this speculation, as soon as he said it, the answer also startled himself, he pondered carefully, this possibility is not impossible, whether the space faults and rifts are accompanied by the distortion of space, thus producing an effect similar to the gravitational field, no one can say clearly, human beings have never encountered this kind of space phenomenon, these theories are only briefly recorded in the materials of Kuafu's early exchanges with Renhe civilization.

Mankind's initial understanding of the universe was limited to a three-dimensional space with three coordinate axes of up, down, left, right, front and back, and six cardinal directions, and the volume was infinite, in which all celestial bodies were distributed and orbited. In addition, there is a one-way forward time axis, the reason why time is only represented by the imaginary axis is because human beings are not clear about the nature of time, and cannot perfectly add it to the three-dimensional spatial coordinate system, so that it can become a part of the four-dimensional universe.

Soon, the advent of the theory of relativity changed the perception of the universe, and in order to facilitate understanding, it was customary to use an elastic, two-dimensional flat plastic film to represent the current three-dimensional universe. This "film" was supposed to be a flat plane, and the size was infinite. But in fact, this "film" is not flat, and a large celestial body can squeeze the film downward like a vortex on the surface of the water, making the space uneven, this deformation is called space curvature, and the degree of deformation is positively related to the mass of the celestial body.

Space has curvature, it can deform objects moving in any straight line, including the trajectory of photons moving at the speed of light, the more massive the celestial body makes the curvature of space greater, the black hole is the most extreme phenomenon, the distorted space within a certain range around the black hole, its curvature can enter the singularity of photons, this limit greater than a certain range of curvature is called the event horizon. Although the unexpected curvature of the event horizon can affect the trajectory of an object, an object moving at the speed of light can leave.

After Kuafu encountered a gravitational wind during the voyage, mankind has a new direction in the study of space, based on the fact that gravity can move and propagate in space like waves, a bit like ripples on the water, but how such a phenomenon occurs cannot be explained yet. The cause of this motion can be explained by quantum mechanics or by the relativistic motion of folds in space, but neither theory can perfectly explain how such a large gravitational force is generated.

The biggest limitation of Kuafu is that the crew base is too small, the scientific research institutions are smaller, the equipment is few, and the connection with the earth has been cut off for a long time, and the theoretical research is basically in a state of stagnation, and even these important information cannot be transmitted to the earth. Just when this discovery was destroyed by the gravitational wind along with Kuafu, humanity encountered the Renhe Civilization Exploration Team, and while they rescued Kuafu, they gave information that brought the human space theory to a new stage.

According to the discovery data of some Renhe civilizations, the three-dimensional space is more complex and broken than human imagination, and in addition to deformation, there are distortions, cracks, and staggered cracks in the space...... In many areas of the universe that humans can't see, space is as chaotic as a torn sheet that has been used for many years and thrown there in a mess. In those chaotic cosmic spaces, any matter is destroyed and fragmented, and it is impossible to produce celestial bodies like stars, and it is a forbidden area for life. Because the solar system is too small, human beings are even smaller, and the spatial scale that can be felt is too small compared to the universe, so those distant space disasters will not affect the solar system where human beings are located.

Of course, this is still part of the characteristics of the universe, Renhe guesses that when civilization can look at the universe from a more macroscopic perspective, the universe is not a complete whole, it is composed of many large and small such space plates, and the space is constantly colliding (of course, the time of human existence is too short to collect this phenomenon in large quantities), causing the space to change constantly, the old and the new are distorted, and the folds and cracks continue to disappear and reappear. These changes have a huge impact on the stability of space, which triggers gravitational winds, larger or smaller, that propagate through space and gradually weaken with time and distance due to the stability of space itself. If it encounters a massive star gravitational field, or a spatial fold, fissure, or fault, it will be rapidly weakened or even canceled out. The solar system in which humans live may be in the middle of a stable region of a space plate, close to the massive body of the Sun, so it is difficult to detect this spatial phenomenon.

Of course, there are many theoretical schools of thought in the civilization of benevolence, and what mankind has gained is only a small part of them.

"It's a possibility." Hachi's system accurately judged the possibility of this guess and expressed it honestly.

"I'll tell you." Jiqing said triumphantly, "I can also do the work of the scientific research department." ”

"Oh, can you theoretically analyze this speculation in detail?" Xiaoba unceremoniously asked more tricky questions, this Jiqing would definitely not be able to do it, and he would be able to open his mind occasionally, really let him do theoretical demonstration work with a high degree of professionalism, which would definitely not work.

"This ...... I don't have enough time, I don't have enough time, and I'm a person who has a job. Jiqing hurriedly shirked and said, I will accept it when I see it, I am really more serious in this matter, Xiaoba definitely embarrassed him, he pretended to flip through the report in front of him, "There is more?" Massive objects? What's going on? ”

"The latter is the most important part of the report, the General Headquarters attaches great importance to the lessons of this mutation, and orders the General Staff to coordinate the whole department to re-evaluate the safety of navigation, and the Scientific Research Department has simulated and found that there is a gravitational field of a more massive moving celestial body in the channel of the Kuafu."

"In other words, it's not the phenomenon that caused the gravitational wind mutation that almost ruined the problem of Kuafu, but that Kuafu is crashing into another celestial body, and the past tense that caused the anomaly is no longer very important."

"This is the value of the gravitational field? How big does this object have to be? And it's still in the channel of the Kwafu, which is troublesome. This information shocked Jiqing's heart, "And there is no light source, what kind of celestial body is this?" ”

"I don't know!"

"Too far away? Can not see? ”

"No, so far, in addition to the gravitational field caused by this celestial body, its existence can be confirmed, and it is not far from Kuafu, but the scientific research department has used all conventional methods to detect the exact distance of this star, but there is no result, and the detection laser light wave has reached all the predicted positions of this celestial body, and it has directly passed through the past, and the curvature is very peculiar......"

"Is it small and the location is not clear?"

"No, the position of the gravitational field is very clear, the error is no more than 2 kilometers, and the form distribution of our light wave lattice completely covers that range, and no reflected waves are received. Now only one explanation has been made, which is beyond common sense, but it is not impossible in the universe......"

“…… This celestial body is disembodied, that is, invisible. ”
