1613 five dimensional theory
“In the opening scene of the movie "Interstellar", Murphy once complained about ghosts in his room as a child, and was laughed at by Tom. His father Cooper obviously didn't believe it, but Cooper patiently tried to dissuade him from his father-in-law. Advise Murphy: If she hopes to explain unknown things through science, then she must record more data, then simulate the model, and then find out the rules..
It is only in the second half of the story that the audience learns that Cooper is actually the ghost in Murphy's room.
When Cooper lost himself deep in the time and space tunnel, he finally appeared in a five-dimensional time and space. He could see Murphy's room - the same scene in different timelines, and he could see the past. , present and future, so Cooper tried to have a conversation with Murphy in his childhood through the time tunnel, leaving clues for Murphy, hoping that Murphy could take him home again..
As an adult, Murphy finally deciphered the code his father left in the room through the time tunnel, and solved the problem of saving the earth in one fell swoop. He became a hero who saved all mankind, and finally redirected his father home..
In other words, the scene where Cooper is in the five-dimensional time and space is crucial to the core message of the entire movie, and it is also the most difficult scene to perform in the entire movie..
For this scene, Christopher built an entire hypercube！
Under normal circumstances, the world that people perceive is a four-dimensional space, which is three spatial dimensions plus a time dimension, while a five-dimensional space-time has four spatial dimensions, which is also called a hypercube. For most people This is a very difficult concept to understand, and it is even more difficult to present it on a big screen..
The mission of Double Negative Company is to use visual effects to present this hypercube. From an artistic creation perspective, they can express the entire concept in a more abstract way; but Christopher is a director who constantly challenges the limits of visual effects, and they finally Or decided to complete the production according to the exact appearance of the hypercube?.
Double Negative's visual effects supervisor Paul Franklin studied with astrophysicist Kip Thorne for nearly six months, and even obtained Kip Thorne's notebook as a treasure, ensuring that Our own production team can create images that comply with the laws based on real physical formulas.
So is the hypercube.
At present, humans still cannot understand the concept of four spatial dimensions, so after discussion, Christopher and Kip arranged for Cooper to fall into one of the faces of the hypercube, and then experience the hypercube from Cooper's perspective, in an easy-to-understand way. way that allows the audience to feel the power of time and space——
Because the faces of the cube are all two-dimensional, the faces of the hypercube are three-dimensional. Nolan designed Cooper to fall into the "three-dimensional face" of the hypercube, which prevented Cooper from being wiped out..
At the same time, Murphy's room is located on another three-dimensional surface of the hypercube. Because of the existence of five-dimensional space-time, it seems that there is only a bookshelf between Cooper and Murphy, and the distance between the two people seems to be within reach. , but actually separated by the entire long river of time and space.
According to Albert Einstein's theory of relativity, it is impossible to go back to the past, even into high-dimensional space and time. However, the movie assumes that gravitational waves can travel through time and affect the past, which also means Therefore, if Cooper wants to change the past, he must be able to see the entire timeline, from the past to the future..
Time in five-dimensional space-time is an entity, just like a line. If you are in it, you can see every moment on the entire line from beginning to end; but if you try to change what happened in the past moment, you can only use gravity. Waves, sending out hints, fluttering their wings like a butterfly effect.
To this end, Paul Franklin led the entire visual effects team to start thinking about what a hypercube should look like, especially how to show the linear time that exists as an entity, and how to further use objects as a medium to show every moment on the timeline. , he had to find a perfect solution from the ordinary, without making the picture cluttered, and at the same time, he had to ensure that the audience could observe the changes in Murphy's room at different moments on the timeline through Cooper's perspective..
It was an almost impossible task, but Double Negative did it.
They shrunk the six images of Murphy's room and made each image emit two vertical lines. These two lines are "time lines." Whenever the timelines intersect, an image of the room will be generated. Just like a quadrant, the intersection of the vertical axis and the horizontal axis can form an intersection point.
Therefore, countless lines can be seen in the entire five-dimensional space-time, which continuously intersect to form countless room images. These images are placed on different vertical and horizontal axes. The specific time can be accurately read based on the quadrant coordinates. At this point, Cooper only needs to float vertically or horizontally along the timeline to see the past or future of Murphy's room..
Such a scene takes time for any audience to understand and digest, and actors are no exception. If the actors don't even know what is going on, how can they accurately express their emotions? Green screen can do it, but green screen cannot help actors feel the true "time travel"”.
Then, the hypercube appeared in front of us.
The space in the center is the three-dimensional plane, which is where Cooper is; while the other spaces are all Murphy's rooms, pictures at different time coordinates..
There are only five rooms now, but in the later stages, these rooms will be expanded to countless, showing all the coordinate points of the entire timeline..
Projectors will also be used during actual filming in the studio. Double Negative will project images generated by time changes onto the surrounding curtain walls. Not only the actors, but the entire filming team can view the interior of the hypercube. Have an intuitive understanding of the timeline——
For a simple example, maybe the space directly above is when Murphy was five years old, the space on the right is when Murphy was sixty-five years old, and the space below is when Murphy was thirty years old. And so on..
In this way, the entire five-dimensional time and space is presented in front of everyone, and then the photography team and lighting team can understand how to choose all the shooting tracks, pictures and angles..
Of course, in the behind-the-scenes production, digital special effects must be added to every frame of the entire scene. The amount of work is unimaginably large..
Christopher's persistence can be seen from the side: the shooting method that combines real scenes and special effects not only affects the actors' performance, but also has an immeasurable impact on the entire shooting team..
When filming "Inception", Christopher built an entire corridor and placed it on a huge rotating machine so that Joseph Gordon-Levitt could shoot the weightless fight scenes in the corridor; now Christopher has built an entire five-dimensional space-time , allowing Renly to complete a "time and space journey" on the movie screen”.
Timothy couldn't help but exclaimed, "So... all the models and props in the center are just for that scene.？”
Just for a mere scene, the wisdom of hundreds of people was concentrated. The consumption of manpower and material resources is definitely not trivial..
Before today, Christopher had discussed the concept of five-dimensional space-time with Renly. To this end, Renly also consulted with Matthew Dunlop to gain a basic understanding of many of the theories. Now he finally saw the entity, shocking and After being surprised, another question came to mind.
“What about the lights?？”
Renly's question earned Christopher a puzzled look - for the lighting, Christopher would definitely make adjustments based on the actual situation, so what's the problem? Renly could only continue to explain:.
“I mean a state of weightlessness. When Cooper is in the fifth-dimensional space-time, he is in a state of weightlessness, right? That’s why he can float up and down and read information at different time coordinates. But if he only relies on wires, how can he express the weightless state? Not only will the body not appear light, but it will also appear bulky.”
When the actor is in the wire state, his limbs are off the ground, making it difficult to control his body, which further amplifies the influence of gravity..
In traditional oriental martial arts movies, the flying effect of flying over the walls requires relying on human power to pull wires. This is a super difficult technical task. It’s not that a master master cannot achieve such an effect; and in the five-dimensional time and space, wires are Relatively still, Renly is hanging in mid-air, and Wia doesn't have much room to pull and move at all - even if there is space, what Christopher needs is not to fly and avoid, but to move in the quadrant of space..
This also means that the actors’ movements are bound to become clumsy, and lighting effects become particularly important..
After filming "Gravity", Renly also had a preliminary understanding of creating the effect of weightlessness. Now the first thought in his mind is lighting..
Christopher opened his mouth and was about to answer. He thought he already had a draft in mind, but after the words came to his mouth, he couldn't help but pause, showing an expression of thinking..
Christopher just stood there and thought for a moment, then turned around and walked away...just walked away..
Renly and others stayed where they were, blinking and unable to react. While looking at each other, Timothy asked cautiously, "Is the director angry?？”
“"Pfft", the three of them couldn't help laughing..
Of course, Christopher was not angry, but went to find the lighting team and visual effects team - this is a very, very serious problem.
Generally speaking, the wire problem is left to the martial arts stunt team, but "Interstellar" has no martial arts scenes, so naturally it is not equipped with a martial arts stunt team. Now the wire problem is completely ignored. If Renly hadn't realized it, They can only wait until they discover the problem after filming starts, and then slowly adjust it, which will be even more troublesome..
