The spacecraft is traveling with difficulty in the black hole, and there is no light at all, Su Xiaojia said: "Now we are just traveling in a gravitational ditch, Zhou Wenbo has a very good grasp, and there is a strong gravitational force on the left and right. ”

"On the right side of the front, there is a grinding sound, not very loud. Not good, above the front, above the ship there is a sound, it's big. "Lin Shanshan is very sensitive to the sound outside.

"I feel like we're in a hole right now, and we can only move forward passively, and we can't dodge. The loud sound in front should be the collision or squeezing of two major objects, but fortunately, the gravitational pull of the black hole is too great, and the gravitational force generated by the two major objects is simply not enough to absorb the spacecraft. Su Xiaojia said.

"But will we just fall off when we fly underneath it?" asked Lin Shanshan.

"Then it's up to fate. Zhou Wenbo said,

"I know, this turbulent wave is caused by the black hole eating in the matter colliding and rubbing against each other, these substances only go in and out, and they are stuffed with things, these things stay in it restlessly, and they are constantly moving, and there will be irregular collisions and squeezes, and such squeezing will produce waves. Ma Biao said, "Oh, by the way, I don't speak. ”

Xu Jiawei thought to himself, the black hole does not seem to be as terrible as the legend, we have been sucked into it for so long, isn't it okay? It should be said that the gravitational pull of the black hole is strong, but the pressure is not as great as the legend, it may also be because of the collision between each other, two or several forces squeezing each other to be flattened or change the matter, it is mistaken for too much pressure. The strong gravitational pull of a black hole can eat any matter, and anything cannot escape after it comes in, even if it is light, so where does this light go when it comes in? If it can be eaten, there must be a place to store it, can you find this place where the light is stored? What will this place where the light is stored? Or there is no such thing as eating light at all, but the black hole itself is too dark, and the light only absorbs and does not reflect light here, so it is misunderstood, thinking that light is also eaten by the black hole. At the same time, the black hole is not what people think, things only enter and do not leave, once anything enters the black hole, it is impossible to run out, and the wave can escape, of course, it is not clear what wave this is.

Suddenly, the spacecraft shook severely, interrupting Xu Jiawei's train of thought. Zhou Wenbo said: "The spaceship was smashed by something falling from above, and since I can't see it, I don't know what the situation is?"

Xu Jiawei said: "Don't care about the situation, we can only follow the current course and passively drive forward, there is no choice." ”

"There was a lot of noise in all directions, and it was as if we were in an area where objects were hitting us intensively. Lin Shanshan said.

"I also feel it, the gravitational ditch in front is very narrow, maybe we have ended here, but unfortunately this experience can not be passed on to the earth, it is not easy to fly such a long distance in a black hole, such a fast speed, I can finally see that the speed is 50 million times the speed of light, flying in a black hole should exceed this speed, maybe we have already flown to the center of the black hole. Su Xiaojia said.

The spacecraft made a loud noise, collided with something heavily, and then deviated from the course, and after a while, they were hit by something else, Xu Jiawei and they staggered in the spaceship, the same as that time in the water balloon, but the intensity was more serious than the water balloon. The spaceship bumped and bumped for a while, and finally quieted for a moment, and suddenly, it seemed to be being chased by something behind, and pushed the spaceship forward heavily.

After a long while, Lin Shanshan said, "There is no sound outside, how can it suddenly be so quiet?"

"I felt like the ship wasn't moving, it seemed to be stuck in place. Su Xiaojia said.

"yes, stay where you are. Zhou Wenbo said.

"Could this be the equilibrium of all kinds of gravitational forces, and we got here by mistake and couldn't advance or retreat?" Mr. Ma said.

"Could it be that this is where we will end forever?" said Luo Dongfang.

The spacecraft flew in the black hole for a while, but it didn't flatten, and now it didn't move, I don't know if it was sucked and didn't move, or it was at the equilibrium point of various gravitational forces in the black hole, and it couldn't go anywhere. There was no electricity, it was pitch black inside, and I didn't know where it was.

Anyway, it's boring, Xu Jiawei said: "Ma Biao, can you try to overhaul the motor or something, and see if it can be restarted." Su Xiaojia, can you put forward a conjecture of the current position, and we will discuss it. ”

Su Xiaojia said: "The captain is really optimistic, it's all at this time, and he still thinks about work." But it's good to think about it, if you can get out. ”

Lin Shanshan said: "Xiaojia, aren't you also more optimistic? ”

Xu Jiawei said: "I have been flying in a black hole for so long, I guess this should be in the center of the black hole." The center of the black hole ......" Xu Jiawei suddenly remembered something and said, "I have a conjecture, let's discuss it together to see if it's right." We're in the center of the black hole right now, because it's the center of the black hole, and all the matter, the whole huge galaxy is revolving around this point, so it's the point of gravitational equilibrium, so the spacecraft can't move where it is. If this is the case, then the center of the black hole should be empty. ”

Su Xiaojia said: "We humans have studied black holes for hundreds of years, and we have been misled by a phenomenon that we believe that light passing through a black hole cannot escape, and that the black hole is a very strong gravitational thing. In fact, when we arrive at the black hole, we know that it is not so terrible, its gravitational force is strong, but its internal is not unified, it sucks in all kinds of matter, does not incorporate the original gravitational force of matter, but allows them to continue to fight arbitrarily inside the black hole, so that there are waves of the black hole, and it will also give the intelligent life that strayed into the black hole a chance to escape from the black hole. ”

"Can we escape from the black hole?" said Luo Dongfang.

"Anything is possible. Xu Jiawei said.

"I'm confident in that. Su Xiaojia said.

"Now it depends on whether Ma Biao can restore the power supply of the spacecraft, and if he can, there is a great hope, because if he can get in, it will be possible to get out. If not, it's hard to tell. Lin Shanshan said.

"If the biosphere is not restored, it will be destroyed, and then our oxygen supply will be a problem. Yang Qi said.

Ma Biao said while touching the equipment: "You have put all the pressure on me, the burden on my shoulders is very heavy." ”

"It's not pressure, it's hope, you're our star of hope now. Xu Jiawei said.

Ma Biao is very familiar with the location of all the electromechanical equipment in the spacecraft, and every key part of these equipment is quite clearly installed in his mind, he is not disturbed by the words of his colleagues, and he can know the quality of this equipment with a touch of his hand, and after overhauling for a while, he is very sure that "the equipment is fine." ”

"Then why can't there be electricity?" Mr. Xu said.

"Strange. Ma Biao said, "The power supply equipment is obviously working." ”

"Isn't our device light? Because we've been in a black hole for so long, there's no light, and all the stored electrical energy is gone. Luo Dongfang said.

"No, it won't. Ma Biao said, "Our equipment is powered by light energy, as long as there is a trace of light outside the spacecraft, it can be converted into powerful light energy, and the excess light will also be converted into stored electricity, this storage function is very powerful, and the storage energy of our spacecraft is enough even if there is no light for 100 years." And there is also a backup quark power generation equipment, and the energy on the ship would not have been a problem. ”

"I see. Xu Jiawei said.

"Captain, do you have a way?" Lin Shanshan said.

"There is no way. I understand the reason for the power outage, Ma Biao, didn't you say that the power supply equipment is still working?"

"yes, it's definitely still working. Ma Biao said.

"We're so confused, we've been in a black hole for so long, and we've forgotten a basic common sense. Xu Jiawei said.

"Captain, what do you mean, don't sell it, say it quickly. Zhou Wenbo said.

"What is the black hole, it is a place where light cannot escape, our power supply system is still working, which means that the energy supply of the spacecraft is still normal, but the light is eaten by the black hole, haha, how did we forget this. Xu Jiawei said.

"Then why wasn't the light absorbed when we first entered the black hole?" Yang Qi asked curiously.

"It's a simple question, it's complicated, and there's nothing to do about it right now, so let's just take it into a more complex way. Xu Jiawei said, "Wasn't Ma Biao the first to discover that the black hole is a turbulent celestial body? After we entered the black hole, it also proved that it was extremely unstable, Su Xiaojia concluded that the gravitational pull of the black hole is strong, but its interior is not unified, it sucks in all kinds of matter, does not incorporate the original gravitational attraction of matter, but allows them to continue to fight arbitrarily inside the black hole. This shows that ordinary light sources are absorbed as soon as they pass through the black hole, but our spacecraft is made of special materials, and the light inside the spacecraft cannot escape, so ordinary gravity will not absorb our light. Now that we are at the center of the black hole, the gravitational pull in the center is quite strong, and the light inside our spacecraft cannot escape the doom of being absorbed. ”

Everyone felt that Xu Jiawei's analysis was reasonable, and they were speechless for a while, and the spacecraft was so quiet that a needle would be heard if it fell.

"Listen, there is a voice. Lin Shanshan said.

"What sound? I didn't hear it. Xu Jiawei said.

Everyone listened very carefully, and they all said they couldn't hear it.

"I hear two different voices, maybe my hearing is more sensitive than yours, then don't speak, let me listen quietly, maybe I can hear the chance to escape. Lin Shanshan said with a smile.
