In Interstellar, the concept of time is not just a plot device — it’s a character in itself. One of the most thought-provoking quotes in the film is "Time is relative… it can stretch and squeeze," said by Dr. Brand (Anne Hathaway). This line introduces the audience to the theory of relativity, where time is affected by gravity and motion.
This idea becomes painfully real when Cooper and his team land on Miller’s planet, where one hour equals seven years on Earth due to its proximity to a massive black hole. The quote serves as a haunting reminder of time’s fragility, especially when Cooper realizes that every passing second means losing precious moments with his daughter back home. Interstellar turns time into an emotional force, making it one of the most impactful elements of the film.
