In the video clip, wearing a crumpled white shirt and a ginger coat, Keene Thorpe stands in front of the blackboard as if he were teaching in a university, explaining the theoretical knowledge of wormholes and black holes in "star crossing".

"Obviously, there are some misunderstandings about black holes and impulses among the general public, mainly because the popularization of theoretical knowledge of physics is relatively slow; At the same time, esoteric theories are also exclusive. It is difficult to pass on the latest developments of quantum mechanics to the public at the first time, which also creates some gaps in knowledge. This will be an important problem to be solved in the future for scientific research and education popularization. "

Keene is still talking to himself with the unique rhythm of professors and scholars, and seems to be doing popular science. Dry words need more attention from the audience.

"That's why Christopher and Jonathan came to me and talked about the interstellar crossing project, and I showed great interest. I think it's a very good opportunity to show the general audience: in fact, physics research is also a very interesting thing."

"First of all, we have to correct a wrong idea of inertia: it is true that large wormholes are difficult to exist naturally, but we have to look at it from a different perspective, just like large computers are not natural places. The absence of large computers in the natural world does not mean that human beings cannot build them through science, It is possible for a sufficiently advanced civilization to build and maintain large wormholes by "artificial" means, which is the same principle as large computers. Sixty years ago, we couldn't imagine the coverage and popularization of the Internet, but now, look at the times we live in. "

"In 2013, two of my colleagues, maldacena of Princeton University and Suskind of Stanford University, wrote a paper that interested audiences can read. In short, they talked about how to build large wormholes in a principled way. As a matter of fact, when Christopher was preparing for this film, I had many exchanges with maldacena and saskat, and finally built a physical model of wormhole for Christopher, which was presented in the film. "

Sitting in front of the computer, William Taylor has been completely confused, staring at the small screen stupidly. There are too many strange words in Kip's words, like a series of random codes, hovering overhead, some understand and some don't understand. But it's certain that after the arrangement and combination, everything will start to dazzle.

William could not help but help his forehead and laughed in silence.

Originally, William wanted to support "Star Trek", watch the behind the scenes gags, and also watch the theoretical framework, so that he could express his support on the social network; Now, he was in a daze, and his mind began to wander into outer space - he tried very hard to concentrate, but it was too difficult!

Keane is constantly explaining the principle of wormhole construction conceived by two physicists. Although he wrote the formula on the blackboard and drew the schematic diagram, he still can't understand it.

"Of course, the cost of building and maintaining wormholes is very expensive, because quantum entanglement pairs may lose entanglement in the disturbance of the environment if they pay little attention, which also means that smaller wormholes will soon evaporate in Hawking radiation. This also means that we need strong enough quantum computing power to correct these entangled pairs in a timely manner, which is why it is difficult to spontaneously form wormholes in the universe, because only a sufficiently advanced civilization can complete the maintenance work. "

"I don't know if the audience has noticed a detail: Cooper once mentioned in the movie that wormholes and black holes were built by the advanced civilization formed by human beings themselves. Maybe this is just a line, but when writing the script, Christopher and Jonathan and I went through repeated deliberation."

"In fact, this can be seen as the limits and edges of the universe that we have explored in the existing human knowledge system, and then assuming that after 100 or 500 years, conditions are ripe, these can be realized. Of course, knowledge is always constantly updated. Maybe after 100 years, our research will be different, but at least in 2014, ’The theoretical knowledge of interstellar crossing is the limit we know

Keane's explanation of the wormhole came to a paragraph for the time being, and then the short video finished switching. He began to talk about how the wormhole in the film evolved from a "theoretical design" to a "real image" on the big screen. He even left the studio and went to the studio to tell the actors how to complete the performance——

When lanli appeared on the small screen, William was finally relieved, and his confused and tense mood relaxed slightly. He began to appreciate lanli's working state with relish.

Make complaints about the "tomorrow's edge" officially released, the group inside the house once heard that the blue rite is the "big devil of the practical joke" rumors, Jennifer, Laurence, Donald - grove, and other actors are not to provoke blue rites, but unfortunately, all are legends, they are all missing.

Unexpectedly, they now have a chance to see the real working state of lanli, which is absolutely a rare precious image.

"I think it's them." Anne Hathaway is wearing a spacesuit and sitting in a one-to-one spaceship. There is no sense of rudeness in the whole picture. The real and appropriate environment completely copies the film picture to the shooting scene. If it is not for Anne's expression showing surprise and amazement, it almost confuses the difference between reality and film.

William immediately recognized that this is the plot of the standing through the wormhole in "Star Trek". Dr. brand saw a fuzzy figure in the distorted space. She tried to contact with each other, and then the whole picture appeared the phenomenon of light and shadow distortion, which is definitely a big impact on the visual effect.

Then, Anne's eyes were in a trance, and she carefully stretched out her right hand toward the camera. The blurred eyes seemed to be confused. Unconsciously and uncontrollably, she pushed her right hand toward the twisted edge. Even if there was an anxious and urgent stop sound in her ear, she still could not help but continue to test the past, just like a child in her childhood, Curious about the touch of the fire, parents in the ear to dissuade, but still can not help but stretch out a finger.

Annie stares at her fingertips in a daze - you can tell the difference. In the movie, brand's fingers begin to twist; But in reality, Annie's fingers still have no change, completely through Annie's performance to show the kind of shock.

At this moment, a right hand came out from the bottom of the camera, which startled William. It looked as if the audience in front of the screen had broken the dimensional wall. But before the shock was released completely, William could not help laughing the next second.

I saw that the right hand slowly raised its index finger a little, and then slightly trembled to detect the past toward Annie, just like the finger touch in the classic movie "et", making a gesture of ready communication, which formed a clever intertextuality with the film plot——

Later, the plot proved that the blurred figure Brandt saw in the distorted image of time and space was Cooper! Two people in the distortion of time and space, completed a touch across time and space, that kind of tremor is really wonderful.

In the process of watching the film, Brandt's fragment has not yet revealed the answer, but is more worried about the unexpected situation; But at this time, watching the gags, the kind of shudder came out from the bottom of his heart, so that William had an impulse to go into the cinema again immediately.

But why did William laugh?

The reason is that the right hand suddenly raised the middle finger slightly, and raised it slightly with the index finger, just like the tentacles of a cricket, and began to stagger up and down to explore. It was like looking for direction or smell. There was no need to move too much, Just rely on the change of hand movements to convey the vivid look.

"Poof Pooh." After all, Annie didn't hold back. All her emotions were brewing. She raised her hand to cover her mouth, raised her head and burst out laughing. As a result, she laughed so hard that even before her tears were dried, her nose also flowed out, which made Aniston feel very embarrassed, "lanli!"

"Ha ha ha ha." Sure enough, it's lanli! William couldn't help laughing.

"Card!" Out of the camera came Nolan's helpless voice, "lanli, let's be serious. What do you think?"

The video is switched from the camera lens to the camera lens for the crew to shoot the gags. Then you can see that Lan Li squats under the camera like a naughty boy, with stable horse steps and a slightly bulky spacesuit on his body, foolishly stretching out his right hand.

Noticing that the camera was aimed at him, lanli said calmly to the camera, "I'm trying to help my colleagues get into the performance state, but obviously they don't appreciate my efforts at all. I feel that I've been misunderstood and hurt. I need to calm down. Would you please turn off the camera for a while?"

The serious nonsense made the photographer laugh and shake with the camera. Nolan, standing not far away, shook his head helplessly. "So what kind of effect are you trying to express? Can you explain the details? "

"Create Adam! You should know Michelangelo's famous mural, right? The mural captures the moment when God gave life to Adam with his own power, and so it is here. Cooper and brand's communication across time and space is not a spiritual transmission of the two life dimensions. At this time, they have a vague foretaste of their fate of destining to be alone, don't you think? You don't think I'm just imitating et, do you? This is too easy to understand! Obviously I'm trying to give the character and the story more weight. "

Er... Is that true?
