Because Huang Chao was present, Old Man Brand was not good at pretending to be mysterious, and explained the problem of gravity anomalies at the beginning, so Cooper knew that the strange sand and dust phenomenon he encountered was driven by an incomprehensible existence in the dark that drove him here. X Cooper feels a sense of responsibility to save the world.

Old Man Brand was still adding fuel to Cooper's persuasion: "You are our best astronaut, you trained for this many years ago. They brought you here. Cooper began to move, but didn't want to be separated from his family: "How long will I go?" ”

The old man frowned: "It's hard to determine, how many years?" Cooper took a deep breath and said, "I still have kids, Professor." "It's not so much that he is rejecting the old man, but that he is hesitating, he feels sorry for the children, and he promises his deceased wife to take care of the children, which is the father's responsibility.

Old man Brand's face remained unchanged, and he said in a deep voice: "Go to space and save them." His solemnity came from the heart, and Cooper understood the meaning of his words, if his children were to live, someone had to spend their sweat and time in space, and even bury their lives in the dark depths. This time Cooper was silent, he already felt his principles.

At this time, Huang Chao did not speak, this was a difficult decision for Cooper to make. Their civilization is to blame for coming to such a difficult point, but Cooper shows the responsibility and responsibility of his father at this moment, but he is still great and respectable. If everyone is a smart person, thinking "I will definitely sacrifice anyway, I will definitely not go", then no one will sacrifice at such a critical moment. Such people are completely the dregs of civilization, and they will justifiably hide behind others when faced with choices, and when they look back on history, they will think that they are mocking the stupidity of the sacrifices of their predecessors. If civilization is all such dregs, there is no power to resist in the face of crisis.

Old Man Brand and Cooper have limited abilities, they can't wave their hands to save the world, and they can't even solve the anti-gravity formula without data. But they did their best to perpetuate civilization and sacrificed themselves for it, and the remnants of humanity on Earth should be thankful that they still have this great spirit among them. Cooper was a mortal, but when he decided to step into deep space, his mind was sublimated.

Human beings are complex, and even Cooper will regret and resent them later, but it will not detract from the brilliance in him at this moment. Human beings have been able to stand out from countless living beings and create a brilliant civilization precisely because of the accumulation of brilliance from generation to generation. Huang Chao looked at Cooper and smiled encouragingly. The old man Brand opposite him saw Huang Chao's smile, and for some reason felt very happy and satisfied, as if his hard work and dedication had been affirmed by the most authority.

Huang Chao coughed: "In this case, count me as one." Old man Brand was stunned for a moment, and quickly replied, "You have decided?" ”

Huang Chao nodded simply, and didn't say anything touching, he had no responsibility for these people, so he didn't bother to put on any touching attitude. Old man Brand's eyes flashed with hesitation, he originally wanted to call Cooper to his office and use a blackboard to increase Cooper's confidence, but now he didn't dare to take Cooper and Hierro with him.

He turned out to bully Cooper who didn't understand, and a layman would only think that this anti-gravity formula was complicated and profound, but Huang Chao, who knew how to do it, would try to solve it by himself if he had an idea. After all, if you solve it, you can save mankind, and no one will be polite to Old Man Brand at this time. Like Mann before, he understood that this formula could not be solved at all, which led to his complete despair.

Huang Chao listened to the briefings of NASA scholars in the conference room, mainly telling Cooper about Saturn's wormholes and the space behind them. Huang Chao didn't want to pour cold water on these people, so he kept a polite smile and nodded from time to time, so that the narrator felt Huang Chao's "serious response". In fact, Huang Chao was speechless about the world, and a wormhole appeared at the door of his home, a wormhole that could stably cross space! They've been on an expedition for fifty years! With this kind of achievement, the destruction of civilization is not unjust at all.

These people in the space agency didn't know Huang Chao's slander, and most of them participated in the expedition to save mankind, and they were excited and excited, full of dedication that made Huang Chao admire and laugh. Cooper was now seriously considering the question, and after a black scholar had finished explaining, he asked Old Man Brand his doubts: "Professor, if we can find a suitable planet, then what can be done to save humanity on Earth?" ”

Everyone smiled at Cooper, Cooper's question, indicating his attitude of joining, and now everyone treats him as their own. Old man Brand showed a confident smile and glanced at Huang Chao quietly: "We have two plans, plan A and plan B, come with me." ”

He led Cooper and Huang Chao to the construction site outside, and the old man Brand showed a mysterious smile: "Look at this building, what do you think it looks like?" As a professional astronaut, Cooper's IQ is completely online, and he tilted his head sideways and quickly saw the mystery: "The whole building here is a huge centrifugal device? ”

Old man Brand smiled and nodded, and Huang Chao said, "So you want to launch the entire building into space as a large space station?" Cooper also realized the irrationality here, how could such a heavy object happen in space! In the past, humans built small space stations, and they had to constantly launch and assemble them in space.

"Ever since I discovered the gravity anomaly, I had the idea that using gravity for interstellar travel is possible. I put forward a hypothesis that if it is perfected, it will be possible to achieve the launch of a large space station. ”

Cooper said a little unpleasantly, "You want us to gamble on your possible completion at the cost of everything we have?" What is that hypothesis? Of course, Cooper understands that this is the crux of the matter, and Old Man Brand is also helpless, as long as he introduces it here, Cooper and Huang Chao will definitely understand its importance.

"When you come back, I'll do it, that's my promise," Brand said. The old man's face was resolute, and there was a solemnity that he would die for it in the next moment, and he calmed Cooper for a while. What comforted the old man was that Huang Chao, who he was most worried about, did not react.

"So what's Plan B?"

As an expert in biology, Miss Brand took over the role of introduction. She led the others to the biology lab, pressed a button on the refrigerated biological sample cabinet, and with the sound of a jet, a sample bucket containing a sample of a human fertilized egg ejected ejected from it. Miss Brand smiled, "Plan B, Super Population Bomb." ”

The plan is to bring these fertilized eggs to habitable planets, and use biochemical means to reproduce them and become a continuation of human civilization. The fertilized eggs are diverse, and the diversity of human beings is maintained as much as possible: this is the transport force that is too low to transport a large number of "living people",
