As they approach a new wormhole, different from the one near Saturn, the team encounters an anomaly—an intense gravitational wave that disrupts their trajectory, sending them to an uncharted region of space. Here, they discover a dying galaxy on the brink of collapse, where time behaves unpredictably. They are not alone; remnants of other civilizations, long since extinct, have left behind clues about the region’s secrets and the nature of the black holes.
Amidst the chaos, Cooper receives strange signals, similar to the ones Murph once decoded, but these are far more complex. It becomes clear that these messages are from future versions of themselves, trapped in a time loop within the black hole’s event horizon. To break free, they must decode these messages and navigate a series of paradoxes that threaten to unravel the very fabric of time and space.
The climax reveals that Cooper’s journey is not just about saving humanity but also about ensuring the survival of time itself. In a mind-bending twist, Cooper realizes that the solution lies not in finding a new home but in using the black hole’s singularity to create a new universe—a rebirth of the cosmos, where humanity can start anew. The film ends with Cooper making the ultimate sacrifice, merging with the black hole to ignite this cosmic rebirth, leaving his legacy as both a savior and creator.
