Are Interstellar and In Time Realistic in Their Depictions of Time Travel?

The question of whether movies accurately depict the fantastical and often advanced topics like time travel is a common one. Films, by their nature, often take creative and artistic liberties with scientific and philosophical concepts. While no movie can perfectly capture the complexities and nuances of time travel—the idea of traveling backwards in time being an absolute impossibility—both Interstellar and In Time present their takes on the subject in different ways.

Interstellar - A Stellar Example of Science-Fantasy

Interstellar, directed by Christopher Nolan, is often cited as one of the more scientifically grounded films in its genre. While the movie contains a fair amount of science fiction tropes and narrative flourishes, it aims to present a realistic portrayal of the kind of science that would underpin such a journey. The key elements, like the mechanics of interstellar travel, time dilation due to gravity, and even the concept of multidimensional space, draw from theories and concepts formulated by real scientists. These include the theories of Einstein and the complex calculations involving gravitational holes and cosmic anomalies that Nolan and his team consulted.

The film delves deep into the scientific aspects of time travel, albeit in a highly stylized manner. Nolan collaborated with physicist Kip Thorne, who worked on the movie’s scientific rigor, to help ensure the film’s depiction was as accurate as possible. Interstellar tackles serious scientific themes, from the impact of gravity on time to the formation of black holes, making it a more grounded and thought-provoking experience for viewers who are scientifically inclined.

In Time - Science Fantasy on Steroids

In comparison, In Time, a film directed by Duncan Jones and written by his father, ringmaster of science fiction, Chris Jones, takes a very different approach. It’s a science fantasy that sacrifices much of the plausibility in favor of existential and philosophical explorations. In Time is set in a futuristic, dystopian society where human lives accumulate time, and once it runs out, you die. This concept, while novel, is far from a realistic treatment of time or time travel.

In the film, time manipulation is a common theme, and characters can purchase additional time by spending “time dollars.” However, the rules and mechanics of this system are not based on any real scientific theories, nor are they presented with the kind of detail and precision found in Interstellar. Instead, the film relies more on emotional and psychological impact. It’s a strongly allegorical and moral story that explores the themes of imprisonment, commodification of life, and dehumanization, using time as a metaphor rather than a physical concept.

Realism in Time Travel - A Continuum

Both Interstellar and In Time fall on a spectrum of realism in their depictions of time travel. While Interstellar strives for a more scientific and grounded approach, In Time is a pure allegory shorn of much of its scientific basis. It’s important to note that both films serve different purposes. Interstellar aims to spark curiosity in viewers about the nature of space and time, using them as stepping stones to deeper philosophical questions. In Time, on the other hand, presents a potent social commentary on consumerism and the value placed on human life.

In conclusion, neither film is strictly “realistic” in their depiction of time travel, but Interstellar makes a more concerted effort to present a scientifically informed and thought-provoking portrayal. In Time, conversely, explores its themes in a purely symbolic and metaphorical fashion, focusing less on the technical details of time travel and more on the ethical and moral questions it raises.

No matter which side of the spectrum you fall on, these films offer a rich tapestry of storytelling and ideas that can inspire viewers to think more deeply about the nature of time, space, and human existence.
