"Interstellar" is a science fiction movie that is loved by the audience, but it involves many physical theories, and many fans say they can't understand it. This article will introduce in detail the various doubts about the movie, and present it to readers in an easy-to-understand way to help fans better understand this movie. Let's explore the science behind Interstellar and feel the charm of science fiction movies.
At the end of Interstellar, how much time did each character go through?
Although at the beginning of Interstellar, we never know what year it is, in the first half of the film, the timeline seems pretty straightforward. Even as the narrative begins to slowly introduce the concept of relativity—gravity causes some characters to experience time differently than others—it's gradual. It is easy to understand that two years have passed on Earth, and it is dormant in a cryogenic hibernation chamber"Eternity"Only a few months had passed for the crew.
But once"Eternity"Arriving at the water planet, the recording of time becomes very tricky. Cooper and Brand only experienced a few hours, while the earthlings, including Murphy, lived another 23 years. However, although Romili is also in Earth Time, he has been in hibernation for a long time, so in those 23 years, he may have only aged a dozen years. By the time they left Aqua, Cooper and Emilia had been away from Earth for months, Murphy and NASA had been 25 years, and Romilly was somewhere in between.
The next big jump occurred during the ejection around Kagantua after Romili's death. While we can't know exactly how many years Cooper and Emilia lost in their follow-up, it's probably around 60 years, because by the end of the film, we learn that Cooper is actually 124 years old, and at the beginning of the film, he may only be in his 30s or 40s. However, despite the fact that Cooper has ridden"Eternity"About 85 years have passed since Murphy and the people on Earth left Earth, but it seems like only a few months to him. The same goes for Emilia, who, like Cooper, has experienced the passage of time, which is why only she and Cooper are the same age at the end of the film as they were at the beginning of the film.
Murphy in InterstellarWhat is the equation to be solved?
Throughout Interstellar, there's a lot to talk about the gravitational equations that Professor Brand and later Murphy spent decades trying out. Brand told Cooper early on that in order to"Plan A"To succeed, that is, to relocate humanity to another new planet, he must be"Eternity"Solve this equation as you explore potential new homes. Later, Brand confessed to Murphy on his deathbed that he always knew that the equation could not be solved without the quantum data inside the black hole, and that Project A was a ** from the beginning.
As for what the equation itself is intended to achieve, this goes back to the recurring theme of gravity in the film. In order for Plan A to succeed, Brand needs to figure out a way to get the entire human race off Earth aboard a huge space station. While humans have the technology to launch a single space shuttle, city-scale space stations are a different story, and sending them into space requires humans to learn to manipulate gravity as they wish. If the gravity equation cannot be solved, humanity simply cannot leave the earth and is destined to die slowly on this dying planet.
However, after Brand's death, Murphy retrieved her from the Cosmic Rubik's Cube"Ghosts"My father got the data from him and finally solved the gravitational equation. Interestingly, since the Cosmic Cube allowed Cooper to communicate in time, Murphy actually had the data she needed to understand the equations years ago, which was encoded in the watch her father had left her, but she didn't realize it.
InterstellarWhere did Cooper Station at the end of the book come from?
The huge cylindrical space station that Cooper finds himself in at the end of Interstellar may seem almost unrecognizable, but we've seen this scene many times. In fact, it's the same NASA underground facility (or another very similar facility) that Cooper and Murphy discovered at the beginning of the film, and Murphy has been working here ever since. Of course, when we saw it before, its curved walls were pure concrete, not cornfields and residential areas, so it's understandable if you think Cooper Station is a brand new location.
When Murphy solves the gravitational equation, NASA can fit some of the humans into their various space stations (we don't know how many, but we can deduce at least two from the dialogue at the end of the film) and launch them into space. Once free of Earth's gravity, they were able to rebuild the station's interior walls into the ground to make more living space for the station's residents. So, even though Cooper Space Station looks very different at the end of the film, we actually see Cooper visit the same facility twice – once on Earth and once in space.
How did Murphy know that Emilia was in ** at the end of "Interstellar"?
At first glance, it seems strange that Cooper spends the entire film trying to get home with the kids, only to take off on his own initiative at the end of the film after about 30 seconds with Murphy. However, aside from the fact that Cooper immediately follows Murphy's advice and flies back to the wormhole to find Emilia, it's easy to wonder how exactly Murphy knows that Emilia is here, or if she's still alive.
Interstellar never gives a definitive answer, but we can make some speculations. When Cooper first wakes up at Cooper Station, he learns that Murphy has been dormant for the past two years, but as soon as Cooper is discovered, she is awakened and immediately sets off to see him. While waiting for Murphy to arrive, Cooper visits the space station, moves in a replica of his old house on Earth, and restores Tarth. We have reason to believe that during this time, he also has fully understood in"Eternity"on what happened. After all, even though he's gone for decades, he's still a NASA pilot who has just returned from an approved mission. Getting his official account of what he has been through will be a top priority.
Given Murphy's importance to NASA and humanity as a whole at the end of Interstellar, it's not hard to assume that Cooper's report will be a copy of it as soon as it's complete. So even though Murphy and Cooper's meeting at the end of the credits is their first meeting in decades, it makes sense that she already knows everything Cooper went through during the mission—including throwing herself into a black hole in order to get Emilia to Edmonds' planet—is also justified.
Isn't the ending of Interstellar a paradox?
When Cooper realized at the end of Interstellar"them"In fact, it is the humans of the future who created the Rubik's Cube and wormholes to help the humans of the past survive, which opens the door to some major problems. One of the most obvious questions is that if there is no survival of the past humans, the future humans will not exist at all, so how can the future humans save the past humans?
This is what is called"Bootstrap paradox"In this theory, the cause of an event is proven to be the result of the same event. It may seem impossible, but there may be a workable explanation in the world of Star Trek. One possibility is that, in"Primitive"In the timeline, humans are indeed extinct on Earth, but Emilia is on the planet Edmonds"Plan B"The colony survived and evolved, eventually developing the ability to travel through time and space, altering the past, creating a new timeline.
Still, there may be a simpler explanation, which is that time in Interstellar is not linear. Multiple characters take the trouble to explain in the film that the way we understand time may actually be very limited, and that the human experience of time in the future may be very different from ours. This may mean that our understanding of cause and effect is not even true, and that our belief that cause must precede effect is actually false. Perhaps, in the world of Interstellar, time is not a line at all, and our belief that cause and effect can only go in one direction highlights our incomprehension of time.
Interstellar is a book written by Kip Thorne, a Nobel Prize winner in physics, an astrophysics giant, and the only scientific advisor behind the film of the same name. This book is known as a masterpiece of popular science books, and its content covers a large amount of scientific knowledge, including astronomy, physics, mathematics and other fields. The book not only introduces the origin and evolution of the universe, but also covers hot topics such as black holes, wormholes, and interstellar travel. If you're interested in science, then Interstellar is an option you can't miss.
