In Christopher Nolan’s Interstellar, humanity faces a global catastrophe: an unknown pathogen wipes out crops, leaving people on the brink of extinction. However, there is a theory that offers a much darker explanation for these events.
Throughout the film, the protagonist, Cooper (Matthew McConaughey), repeatedly mentions the mysterious 'they,' who are later revealed to be future humans who have learned to exist in five dimensions and can influence the past. In the film’s first act, the characters even 'interact' with these beings.
It is 'they' who guide Cooper and his team, helping them find a new home for humanity.

According to a wild yet plausible theory, these advanced descendants created the catastrophe on Earth themselves to force their ancestors to leave the planet and begin space expansion. By intervening in the past, they ensured their own existence and evolution to the point where they could manipulate time and space.
This hypothesis adds a new layer to the film: humanity becomes both the victim and the architect of its own fate. By creating conditions that necessitate the search for a new home, future humans set in motion a cycle of events leading to their own emergence.
Thus, Interstellar is not only about survival and space exploration but also raises questions about predestination, evolution, and humanity’s role in shaping its own destiny.
