Interstellar presents a complex story with intricate narrative structures that might be difficult for some viewers to fully comprehend. To fully understand the ending, further clarification and explanation are necessary.
We delve into the intricate conclusion of "Interstellar" and explore how time and space relativity come to play in the film.
Like many Christopher Nolan films, Interstellar presents a number of intricate story ideas that may be confusing for certain moviegoers, especially after a first viewing. There are big sci-fi concepts at play, from the environments of the different planets to the way Nolan plays with time. It all builds to an ending that ties everything together but is not always easy to follow how it is all done. In order for some viewers to truly understand the Interstellar ending, they may need some further explanation.
Here are five small Interstellar details that you may notice on a rewatch:
-
Nolan uses a recurring motif of mirrors throughout the film, both literally and metaphorically, to explore themes of identity and reflection.
-
The film's soundtrack features a diverse range of music, including traditional Chinese opera, electronica, and orchestral pieces, which adds to the film's atmosphere and emotional impact.
-
Interstellar features a number of subtle visual effects and props that add depth and realism to the film. For example, the film features a "dream" sequence where the characters experience different versions of their lives.
-
The film's dialogue is often ambiguous and philosophical, and it is not always clear what characters are saying or what they mean. This can be frustrating for some viewers, but it also adds to the film's mystique and complexity.
-
Interstellar is a visually stunning film, and the cinematography and production design are top-notch. The film's attention to detail and technical mastery are evident in every frame.
Early on in the film, it is revealed that the US government has been secretly funding a NASA project to find humankind a new home. Since Earth in Interstellar's version of the future is ravaged by blight and cannot sustain agriculture, Cooper questions how NASA intends to find a planet capable of sustaining human life since humanity is already living on borrowed time, and transport to the nearest galaxy alone would take decades.
The wormhole essentially acts as a bridge connecting two points in space by leveraging imperceptible fourth-dimensional space. With thirteen humans having already traversed the wormhole in search of suitable planets, NASA has been tracking their beacons for nearly a decade. However, only three beacons remain active, posing a significant challenge to the crew's mission. Cooper and the Endurance crew must investigate the fate of the other astronauts and gather any relevant data to make a well-informed decision about which planet holds greater potential for human colonization.
NASA Develops Two Plans to Save Humanity After the Endurance Team Finds a Habitable Planet
Plan A) While the Endurance team is away, NASA plans to continue developing an advanced equation that, if solved, will allow humans to harness fifth-dimensional physics - specifically gravity. Should the equation be solved, NASA will be able to defy the traditional understanding of physics and launch an enormous space station (carrying the remainder of Earth's surviving population) into space.
Plan B) Should the Endurance team fail and/or the equation takes too long investigating potential homeworlds, NASA harvested a bank of fertilized human embryos to be used to ensure humanity's survival. To ensure genetic diversity, NASA procured DNA from a wide range of sources - so that future generations would not be limited to reproduction between Endurance members.
Plan A would allow the first generation of embryos to be raised and nurture the next generation, eventually resulting in the creation of a new population that could potentially save humanity.
Upon learning that Plan A was a farce, Cooper and Amelia Brand (Anne Hathaway) commit to Plan B on their final planetary option, where Amelia's astronaut lover, Wolf Edmonds, was still reporting a positive beacon. Yet, Cooper remains unconvinced that Plan A is impossible and, as they use a nearby black hole (dubbed Gargantua) to slingshot Endurance toward Edmonds' planet, Cooper sends TARS (the crew's robot helper) into the center of Gargantua - in the hopes that it can translate data that might help NASA refine any missteps in Professor Brand's calculations.
Cooper and the other Interstellar characters assume "They" are a sophisticated extraterrestrial race capable of manipulating the very fabric of reality. Their decision to aid humanity in escaping their doomed planet is fueled by an inexplicable desire to help a species transcend the limitations of the physical world. Despite the challenges posed by their advanced technology and cryptic messages, the NASA team believes that "They" are capable of guiding humans to safety through the wormhole, an extraordinary shortcut that defies the laws of physics. However, as the story unfolds in the final act of Interstellar, it is revealed that "They" are actually a union of two distinct yet related entities, highlighting the complexities and mysteries surrounding the universe.
Future humans who have mastered the laws of the universe, allowing them to manipulate time and space, sought to communicate with their daughter inside the enigmatic "Tesseract." Built by the future humans for them, this vast chamber defied the known laws of space and time, granting infinite possibilities.
Cooper's sacrifice, an act of selfless devotion to ensure Plan B, brought him face-to-face with the gravitational singularity of the black hole that formed the Tesseract. Instead of succumbing to its pull, Cooper defied the laws of physics, ejecting from the black hole's gravitational pull and landing safely within the Tesseract's swirling portals.
Since Cooper and Murph are remembered as the saviors of humanity, the fifth-dimensional humans - who can observe past, present, and future - custom-build The Tesseract for Cooper, so that he can communicate with his daughter in the past and relay the data that TARS had collected inside the singularity. To achieve this, the Tesseract acts as a filter that translates the fifth dimension into three-dimensional visibility (tuned to Murph's room) - allowing Cooper to visit his daughter at any point in time.
Interstellar is based on the intriguing ideas of theoretical physicist Kip Thorne, proposing the existence of multiple, additional spatial dimensions beyond the three dimensions commonly observed. Certain theories suggest that forces like gravity could leak between these extra dimensions, leading to infinite implications based on Newton's Laws. Christopher Nolan's movies frequently explore the concept of time, with Interstellar being a shining example. The film's time distillation theory, where the first planet visited by the Endurance team exemplifies this concept, exemplifies the extraordinary nature of time in the universe.
In general, time on Miller's planet's side of the wormhole moves significantly slower than time on the uncharted side due to the proximity to gravitational anomalies from a nearby black hole (Gargantua). This phenomenon causes time on Miller's planet to experience exponential slowing-down relative to the distance between an object and the black hole's gravitational pull. As a result, time on Miller's planet is so slow that it effectively prevents the Endurance team from spending sufficient time on the water planet to achieve any meaningful results.
The concept is further hammered home when, following the mission, Amelia and Cooper reunite with Romilly, who stayed behind on the Endurance to gather data (far from Gargantua) - and, in the three hours his team was gone, has lived twenty-three full years alone without them. Similarly, the crew receives video messages from back home and Cooper's children, Tom and Murph, who have also aged from the beginning of Interstellar's timeline - now full-grown adults (played by Casey Affleck and Jessica Chastain, respectively).
A tangible effect of gravity on spacetime also plays a crucial role in Cooper's ability to communicate with young Murph within the Tesseract. Gravity bleeds through to other dimensions in time and space, allowing Cooper to convey a message ("S-T-A-Y") by manipulating Murph's shelf and spreading dust on the floor (in binary language).
When it comes to how Cooper survives and reunites with Murph, Nolan's theory, which has been present throughout the film, proves insufficient. Given the vast difference in the relative timeframes for Cooper and the rest of humanity, it becomes evident that Cooper's ejection from the Tesseract is only a matter of seconds, but for the majority of humanity, it stretches over half a century.Knowing that Cooper has nothing left to live for in a post-Earth existence (since his son Tom is presumed dead and Murph will soon join him), Murph reminds her father that, through the wormhole, Amelia is just beginning to set up Plan B on Edmonds' planet. At the same time, it is revealed that even though Edmonds' planet is actually habitable, the astronaut himself did not survive the landing - leaving Amelia alone at the colonization site.
Using a reversal of the film's primary relativity theory, Cooper hops into a ship, with the knowledge that even though nearly one hundred years have passed since the Endurance first set out, time on the other side of the wormhole is moving much slower - meaning that a second trip should allow him to reunite with Amelia on Edmonds' planet only a short time after Cooper first sacrificed himself and dropped into the singularity.
The ending to Interstellar doesn't reveal if Cooper and Amelia reunite, but it certainly hints at a happy ending.
The Repeated Quote From Prof. Brand Sums Up The Movie
Interstellar is a film about venturing into the unknown. Much like Nolan's mind-bending sci-fi drama Inception, the main takeaway from the end of Interstellar is not that Cooper and Amelia will be reunited (though it's possible that they will). Rather, the ending, and Cooper's departure to find Amelia illustrates what Prof. Brand regularly suggested by way of poet Dylan Thomas: "Do not go gentle into that good night, old age should burn and rage at close of day. Rage, rage against the dying of the light."
A group of explorers has discovered a wormhole that allows them to travel through vast interstellar distances with ease. This opens up a new era of exploration and discovery, as they can now travel to distant planets and explore the vastness of the universe.
