Things gradually became clear, as Cooper slowly calmed down from infinite loneliness and disintegration, all the context became clear.

It's the future human beings. In the distant future, "they" know the devastating blow that the earth once faced, so they put wormholes next to Saturn, so they found black holes next to the planet, so they built this five-dimensional space in the black hole, guided Cooper here, and then completed the plan to save human beings, Through the time and gravity of black holes, we can change the time that "can never flow backward" - if time can not flow backward, then they will go through the past in the future, and then change the past in a way that can change the future.

What Professor brand calls "them" is actually themselves.

It's him who sends out a signal through gravity, which indicates the coordinates of NASA. But the real goal is not for Cooper, but for Murphy, because he can send back the coordinates of the singularity of the black hole through gravity, and then Murphy can solve the equation left over by Brandt's teaching, so that the first scheme can be implemented again, Also let the earth's human beings have a chance of life.

It's his Murphy.

Murphy finally found out the secret of the watch, held up the watch and rushed out of his room, shouting to the angry Tom, "he's back, it's always him, I didn't know before, but it's him! Dad will save us Then Murphy hugged Tom tightly.

Graham's tears have completely burst the dike, it is love that makes brand fly towards Edmund's planet; It is love that enables Cooper and Murphy to overcome time and space and connect with each other again; Also love, let the earth's human beings have hope again in the end of the world.

What a cliche and rigid core of the story, even sensational soul chicken soup. But at this moment, Graham is watching the picture, and Murphy gradually shows a resolute look - so similar to Cooper, but he can't cry. That warm and tough force makes him completely disarm.

Murphy read the signal from her father and found the singularity of the black hole.

Then, the five-dimensional space inside the black hole begins to collapse.

Between the distortions of time and space, Cooper saw brand again——

At the beginning of interstellar travel, when he first came into contact with the huge impact of black holes, brand tried to touch those distorted images in the space-time warp; In fact, those images are Cooper now. They broke the barriers of time and space between the past and the present, and completed the "et" communication for the first time.

The black hole disappeared, Cooper lost consciousness, floated near the wormhole next to Saturn, and then, far away, humans came to rescue him.

When he opened his eyes again, Cooper was already in the hospital which was all white, which made him have an incredible illusion. The only idea in his mind was "dream". Now he is dead, and all the scenes he saw at this time are his imaginary dreams, which is the only explanation.

But the doctor at the end of the bed is trying to explain, "slow down, Mr. Cooper. Remember, you are no longer a young man. In fact, you are 124 years old now

Cooper's mouth rose slightly, some self mocking, some teasing, as if he thought the other person's joke was really good. He slowly stood up, came to the window, opened the curtain, ready to see with his own eyes how all this is going on.

"Take your time, sir. You're very lucky. When the Ranger arrives, you'll have only a few minutes of oxygen left The doctor's voice was still ringing in his ears.

Cooper had already seen the scene outside the window, the teenagers playing baseball, and then the whole city rolled up to the sky like a reel, with houses and streets above his head. Such a strange scene filled Cooper with confusion. He finally said the first sentence, "er... Cough..." because he had not spoken for a long time, his voice was a little hoarse, "I... where am I?"

"Cooper space station." "It's orbiting Saturn right now," the doctor said The space station is not named after Cooper, but after Murphy.

Then Cooper thought, "is she still alive?"

"She'll be here in two weeks." The doctor nodded in the affirmative, "she's too old to travel between space stations, but when she heard that she found you... She's Murphy Cooper!"

From the doctor's words, Cooper can taste the respect and admiration, which makes Cooper's smile on the corner of his mouth rise, and his eyes twinkle with pride, and he says, "I think so."

Murphy rebuilt the as like as two peas in the Cooper space station, and his childhood home. All the furniture and environment were exactly the same as Cooper's memory, as if he had never left the house. The only difference is that now the house has become a museum for people to visit.

Two weeks later, Cooper saw Murphy again, only to know that he was about to face a big family. When he opened the door of the ward, he saw the whole room full of strangers, from the old man to the children, all around the bed, waiting for a white haired old man.

Cooper's steps stopped slightly for a moment and looked at the old man on the hospital bed. Her eyes flickered slightly, but she didn't know what to do. Then she was already sobbing. She looked at Cooper eagerly, trembling and stretching out her left hand with the watch, and cautiously approached Cooper.

On the hospital bed, it was an old man. The vitality seemed to be slowly passing away. The sparse hair and wrinkled face clearly recorded the traces of time.

Next to the hospital bed, he was a young man full of vigor. After shaving all his beard, Cooper even looked a little bit childish.

But the old man was a daughter, and the young man was a father. This dislocation created a wonderful and moving atmosphere between the two people.

Cooper took Murphy's left hand and rubbed it gently on his cheek. The faint light in his eyes turned into tears. He gently raised the corner of his mouth and jokingly said, "you tell them I like farming?"

This immediately made Murphy laugh.

"It's me, Murphy. I'm your ghost." Cooper whispered.

Murphy's eyes were full of satisfaction. "I know. They don't believe me. They think I did it all by myself, but I know whose credit it is. " She raised her left hand, showed her watch to her father, and raised her chin just as her little daughter wanted praise.

Cooper raised his right hand and tried to touch Murphy's head, but his right hand stopped for a moment, revealed a little hesitation, and finally fell down carefully.

Murphy looked comfortable. "They don't believe me, but I know you'll be back."

"How do you know?" Cooper asked.

Murphy laughed brightly. "Because my father promised me."

Cooper's eyes reddened again. "I'm here now."

But Murphy shook his head. "No, no father should watch his children leave. My children are all here now. You should leave. "

"Where?" Cooper's voice is trembling slightly. The people in front of him are clearly his closest ones, but the time gap has cruelly separated them. Even if he returns to his home, those people in his home are no longer there. He is still alone.

That kind of loneliness flickered in Cooper's eyes.

"Brand." Murphy gave an unexpected answer: "she's still there, building camp; Alone, in a strange galaxy, perhaps she has now built a new home, bathed in new sunshine

Brand arrived on Edmonds' planet, but Edmonds was no longer there. Although humans have built different space stations around Saturn, brand did not choose to come back. Instead, he stayed on Edmund's planet and continued to build a base suitable for human survival.

be on one's own.

Like Cooper, brand and they both survived, but both of them were alone. The separation of yin and Yang left brand alone in the world, while time and space separated Cooper from the world of Tom and Murphy. As a result, the two people who had experienced all that became the last dependence between them.

Only they can understand each other, everything else has nothing to do with them, just like another world.

That loneliness, that loneliness, that loss, let their souls become at a loss. Even if Cooper has returned to Murphy's side, but around Murphy's bed are a group of strangers, strangers who are related by blood but have no family ties. Cooper is just like brand.

So, Cooper took the repaired tars, stole a plane in the middle of the night, and went on the journey again to Edmunds' planet to find brand. Two lonely souls, on a brand new planet, set up their own home.

Cooper sat in the driver's seat, his calm eyes didn't fluctuate or shine, just like the deep night, which seemed to have no stars. He started the aircraft step by step and flew towards the unknown in the distance. In a trance, he seemed to go back to the distant past again

At that time, his aircraft went out of control and crashed. Then he became a farmer and had to start a new life in the end of the world. Now he has entered a new cycle again.

But Cooper did not have any fear or worry. His calm eyes burst out with a sense of tolerance. He could catch a trace of lonely confusion and struggle. Then he was replaced by a glimmer of hope, weak but bright. In this way, he dashed forward again without advance and unswervingly.

Black screen.

end.

The movie, it's over.
