Back in town, Pang Xuelin couldn't help but have a headache.

He had a vague suspicion that Cooper had deliberately cut off ties with NASA and lived his peaceful life on a farm in the countryside.

In the movie, Cooper later chose to re-emerge from the mountain, the main reason is that the environment on the earth is deteriorating year by year, and he has two children and no hope for the future.

In addition, he accidentally found NASA and found that Professor Brand had started Project Lazarus, hoping to keep his children alive.

That's why he chose to join Project Lazarus.

And now, his wife is pregnant, his little daughter has not yet been born, and for him, the good life has just begun.

Therefore, when he finds him for the first time, the other party will refuse as soon as possible.

However, Pang Xuelin is not worried.

His main purpose in looking for Cooper was for his family's attic.

If his guess is correct, the future Cooper will be trapped in the timeline where his attic space is located after falling into the fifth dimensional space-time.

As long as he appears in his attic, he will definitely be seen by Cooper who is trapped in the fifth dimension of time and space in the future.

As for how to make Cooper in the fifth dimension of space-time transmit black hole information to himself, it depends on what kind of words he says to Cooper now.

After spending one night in the town of Nora, Pang Xuelin went to Cooper's house again the next day.

Bang bang bang –

After knocking on the door for a while, what appeared in front of Pang Xuelin was still a double-barreled shotgun.

"Why are you still here, don't you understand what we're saying? There's no Cooper you're looking for! ”

Cooper's father-in-law, Donald, raised his shotgun and shouted angrily.

Pang Xuelin raised his hands and said loudly: "Mr. Cooper, I don't mean anything else, I didn't come here this time to let you go back to join the NASA, I just need to talk to you in the attic of your house, and I will leave after that, and promise not to disturb your life from now on!" ”

Donald said: "I'll tell you here, there's no Cooper you're looking for here, get out of here!" ”

Pang Xuelin was a little helpless, took two steps back, and said loudly again: "Mr. Cooper, what I said is true, if you still don't want to see me, I can only come back tomorrow!" ”

"Stinky boy, don't you get out of here!"

Donald put his shotgun to Pang Xuelin's chest again.

At this moment, a gentle female voice came from behind Donald: "Daddy, let him in." ”

Donald also looked back in surprise and said, "Evelyn, why did you come out?" Storehouse...... What about him? ”

Evelyn didn't answer Donald's words, but smiled and said to Pang Xuelin: "Cooper is in the living room, if you want to find him, go now." ”

"Mrs. Cooper, bother!"

Pang Xuelin smiled at Evelyn, removed the shotgun from Donald's hand, and went straight into the house.

In the living room, Cooper sat on the sofa, his face not very good-looking.

Pang Xuelin came to Cooper with a smile, stretched out his hand and said, "Mr. Cooper, I am Pang Xuelin, the captain of the astronaut brigade of the Space Administration......"

Cooper looked up at him and said, "I'll give you five minutes to convince me." ”

Pang Xuelin withdrew his hand and said, "Okay, then let's make a long story short." Mr. Cooper, do you believe in fate? ”

"Fate?"

Cooper looked at Pang Xuelin in surprise.

Pang Xuelin smiled faintly: "Can you take me to your attic?" ”

"My attic?"

Cooper hesitated, got up and said, "Captain Pang, please." ”

Pang Xuelin nodded with a smile and followed Cooper upstairs.

The attic is actually a large study with a huge bookshelf that fills all the walls and is filled with all kinds of books.

The vast majority of them are specialized books in the fields of aerospace and science and engineering.

Pang Xuelin turned around for a while, turned around and said with a smile: "Mr. Cooper, it seems that you still haven't forgotten your former mission." ”

Cooper said lightly: "It's just too lazy to lose it, just take a look at it to pass the time." ”

Pang Xuelin smiled and said, "Okay, Mr. Cooper, let's get down to business. My next question is an important one, and I hope you will always keep it in your mind, no matter when, even when you are on the verge of death. ”

"What's the problem?"

Cooper was slightly stunned, and his face gradually became solemn.

Pang Xuelin said: "In the attic of your house, have there been some strange phenomena? For example, when no one is around, the book suddenly falls to the ground, or when the gravity is abnormal, during the sandstorm, the falling sand and dust speed is inconsistent, which can form light and dark stripes on the ground, and the hands of the watch in front of me are constantly moving around......"

Pang Xuelin picked up a watch on the bookshelf that had stopped turning and looked at Cooper.

Cooper was a little confused and puzzled: "Captain Pang, our attic has always been normal, nothing strange has happened, and besides, I don't understand what you mean?" ”

Pang Xuelin laughed and said, "Maybe you don't understand what it means now, but I think maybe the next moment, maybe when your daughter is born, maybe when your daughter starts school...... You get the idea. ”

“……”

Cooper looked at Pang Xuelin as if he was looking at a fool.

Bang Dang –

Just then, a book on the shelf suddenly dropped.

Pang Xuelin turned around in an instant, looking at the book that had fallen from the shelf, and his eyes flashed with ecstasy.

Cooper, on the other hand, looked at Pang Xuelin dumbfounded, and then he looked at the book and said, "Maybe this book was not put away, it was an accident......

With that, Cooper stepped forward and put the thick ship operation guide back on the shelf.

The next moment, the entire bookshelf shook violently, and a book was automatically removed from the bookshelf and fell to the ground.

At this time, Donald and Evelyn also rushed upstairs, stunned and stared at everything in front of them.

Cooper was dumbfounded.

After a long while, he turned his gaze to Pang Xuelin and said, "Captain Pang, can you tell me what happened?" ”

Pang Xuelin shook his head, and all his attention was on the watch in his hand.

"Cooper, give me paper and pen."

"Oh, good!"

Soon, Cooper found a pen and paper, and then stood beside Pang Xuelin, looking at his watch curiously.

I saw that the hands of the watch were shaking constantly, and the duration was short.

Cooper was stunned and turned his gaze to the blank paper that Pang Xuelin was recording.

Pang Xuelin kept writing strange symbols on it.

Dots and dots, dots, dots, ......dots,

"It's ...... Morse code? ”

Cooper was the first to reflect.

Pang Xuelin nodded and said, "What I wanted, I found it!" ”

……

Half an hour later, I double-checked it several times to make sure that there was nothing wrong with the Morse code I had memorized.

Pang Xuelin tore off the white paper and said with a sigh of relief: "It's okay." ”

Cooper said, "Captain Pang, can you tell me now what's going on?" ”

Pang Xuelin smiled faintly and said, "Cooper, it's not that I won't tell you, I think it's better for you not to know about this matter, unless you want to become an astronaut again and join the astronaut team of the Space Administration." ”

Cooper was slightly stunned, pondered for a long time, and sighed, "Forget it." ”

Seeing that Pang Xuelin really didn't mean to find Cooper to return to NASA, Donald looked at Pang Xuelin with a lot less guard.

That night, Evelyn cooked a rich meal to entertain Pang Xuelin.

After dinner, everyone sat on the sofa and chatted, and before they knew it, they talked about the child in Evelyn's belly.

Cooper suddenly seemed to remember something, and said, "Captain Pang, is it true that you said that Evelyn would give birth to a girl in the future?" ”

Pang Xuelin nodded with a smile and said, "Eight or nine is not far from ten." ”

Pang Xuelin didn't dare to say 100% certainly, because his actions during the day would inevitably change the direction of Cooper's life in the future.

It's like an eternal topic in the grandfather paradox, if someone travels back in time and kills your grandfather before your father is born, then does the future you still exist?

If we look at it in a one-dimensional linear view of time, there is a contradiction in this.

But what if time is two-dimensional?

The possibilities are endless.

According to the original development of this space-time, Cooper will join the Lazarus Project in the future, go through several life and death disasters, and finally fall into the black hole and enter the five-dimensional space-time, and then be trapped in the five-dimensional space-time formed by his attic study, trying to transmit the information in the black hole to his daughter Murphy.

After knowing that Murphy became an adult and became a physicist, she realized that all the strange phenomena that happened in the attic from her childhood to adulthood were all messages sent back to her by her father who had fallen into the fifth dimensional space-time.

Later, it was Murphy who decoded Cook's information and allowed human civilization to continue in space.

Now, Pang Xuelin came to find Cooper in advance and told him now that some strange phenomena would happen in the attic.

Then Cooper in the future five-dimensional space-time may get such information, so as to transmit the internal data of the black hole to Pang Xuelin when he first came to the attic through the attic space.

This was a conjecture by Pang Xuelin, and fortunately, his conjecture was verified.

However, now that he has obtained the internal data of the black hole in advance, whether it will change Cooper's fate in the future, and where Cooper's future will go, Pang Xuelin does not know.

It was as if he had reopened a river in the same direction, and some of the fish in the river continued to move along the original course, while others entered the new channel and swam to the new unknown.

Cooper is undoubtedly one of these fish swimming into the unknown.

As for Cooper at this time, when he heard Pang Xuelin say that he would have a daughter in the future, he was happy and couldn't help himself.

After experiencing the strange events before, Cooper already had an inexplicable trust in Pang Xuelin in his heart.

"Evelyn, Captain Pang said we'd have a daughter, if it's a daughter, how about we call her Murphy? Murphy Cooper, I think that's a great name. ”

Evelyn smiled, "I think it's a good name. ”

At this time, Pang Xuelin said with a strange face: "Mr. Cooper, you'd better not take this name." ”

"Why?"

Cooper was a little surprised.

Pang Xuelin said with a smile: "The name Murphy has been preemptively registered by me, and my daughter's name is Murphy." ”

"Huh? Such a coincidence? ”

Cooper was surprised.

Evelyn on the side smiled and said, "Captain Pang, since you stole our Murphy's name, then you can help us pick one up." ”

Cooper smiled, "Yes, Captain Pang, you have to return a name." ”

Pang Xuelin smiled: "How about calling Edith?" Edith Cooper. ”

"Edith Cooper?"

Cooper and his wife looked at each other, and both of them had satisfied smiles on their faces: "That's a good name!" ”

……

Early the next morning, Pang Xuelin said goodbye to the Coopers, and spent nearly ten hours driving back to NASA, where he met the wise little old man in Professor Brand's office.

"Pong, you're finally back, how are you, have you found that Mr. Cooper?"

Pang Xuelin smiled: "I found it." ”

"What about the others?" Pang Xuelin took out a stack of manuscript paper from the briefcase he was carrying, handed it to Professor Brand and said, "He has a beautiful wife now, and maybe he will have a lovely daughter in the near future, and his life is very happy, I don't want to spoil this beauty." However, this time I was not without gains. ”

"Harvest, what harvest?"

Brand looked at Pang Xuelin curiously.

Pang Xuelin said with a smile: "You can understand it by looking at the content on the manuscript paper." ”

Last night, he substituted the data he got from Cooper in the fifth dimension of space-time into the system of equations given by Dawbrand, and easily solved the basic parameter equation of the graviton.

The rest of the work will depend on how NASA puts this theoretical breakthrough into engineering practice.

Brand didn't speak, but looked at the contents of the manuscript paper word by word.

Gradually, the expression on his face changed.

From the beginning of the relaxation, slowly became dignified, and later, began to become surprising, and a trace of incredible.

Finally, he raised his head and looked at Pang Xuelin, and said in a trembling voice: "Pang, how did you do it?" ”

Pang Xuelin shrugged his shoulders and smiled: "In short, our most difficult step has been completed, hasn't it?" Also, I feel that Plan B can be canceled, and we have every chance to save all of humanity! ”

Brand stared widen suddenly, looked at Pang Xuelin incredulously and said, "You...... You got it? ”

Pang Xuelin said: "I'm not stupid, after reading your theoretical formula that day, I knew that under the existing experimental technical conditions, it is impossible to get the parameters you want, and with our current level of space industry, there is no way to support large-scale space migration by human beings." Therefore, the real Lazarus Project is just to train a group of human elite astronauts, take the essence of human civilization and a large number of fertilized eggs, and go to a new world to reopen human civilization. ”

Brand looked at Pang Xuelin silently and did not speak.

After a long time, he let out a long sigh and said, "Pang, no matter how you did it, in short, thank you!" ”

Pang Xuelin smiled faintly and said, "You're welcome, Professor Brand." I think there is more important work ahead of us. ”

"What job?"

Brand was slightly stunned.

Pang Xuelin said: "Reformulate the Lazarus plan, the Eternal Night spacecraft is too simple, the previous plan is completely consuming the lives of elite astronauts and fighting for the luck of human civilization, but now, we don't need to do this." As long as we can reduce the cost of going into space on a large scale, we can make the whole program and our spacecraft better, and we can have a higher level of safety for explorers. ”

Brand nodded and said, "Your idea is very good, I will propose it to the top as soon as possible." ”

Pang Xuelin nodded and said, "Professor Brand, if there is nothing wrong, then I will go back first, I haven't been home for almost three months, I have to accompany my family well." ”

Brand smiled: "No problem, I'll give you a month's vacation, but after a month, you have to report to me, and you need to lead the new Lazarus Project next." ”

"Well, in a month, I'll definitely be back."

Pang Xuelin nodded, and said with a straight face.

……

Coming out of Brand's office, Pang Xuelin smiled.

New technology, new ships, new Project Lazarus.

This is not only a guarantee for the safety of their own lives, but also a guarantee for the lives of those astronauts who participate in this program.

Pang Xuelin shook his head and was about to go back to his office when he heard a cry of surprise behind him.

Pang Xuelin turned around and saw Murphy trotting all the way towards him, shouting at the same time: "Brother-in-law! ”

Pang Xuelin subconsciously opened his arms and took Murphy into his arms.

The two hugged quietly for a while, and then Pang Xuelin let go of Murphy.

Murphy's face flashed with a hint of warmth, and said, "Brother-in-law, you finally appeared, where have you been for more than two months?" I asked Professor Brand, and Professor Brand didn't say anything. ”

Pang Xuelin said with a smile: "I have something to do, and I went on a business trip." The trip went well, and Professor Brand rewarded me with a month's vacation. ”

"A month's vacation?" Murphy was surprised, "That old man is so generous? Then I'll try it too. ”

Ten minutes later, Murphy came out of Brand's office dejectedly.

Pang Xuelin smiled: "Murphy, how is it?" Did Professor Brand agree to give you time off? ”

Murphy said with a sad face, "Professor Brand said he could give me a long vacation, but I don't want to participate in the Lazarus Project......"

Pang Xuelin pursed his lips and smiled: "I think this proposal is good, do you want to try it?" ”

"Hey, brother-in-law, don't!"

Murphy said hurriedly.

The reason why she tried her best to join the Lazarus Project was so that she could be by her brother-in-law's side when Pang Xuelin went on an expedition.

Compared to this, just a one-month vacation is naturally nothing.

Pang Xuelin said with a smile: "Okay, I'm going to go home later, do you want to go back with my car?" ”

"Oh, okay, brother-in-law, you wait for me, I'll go back to the office for that something......"

With that, Murphy ran to the end of the hallway without looking back.

Looking at Murphy's slender figure, Pang Xuelin smiled and did not speak.
