The tesseract in the movie Interstellar is a very special place that helps the main character, Cooper, communicate with his daughter Murph in the past. It is like a four-dimensional cube, which means it can exist in many different times at once. This allows Cooper to move through time and space in a way that seems like magic to us.
When Cooper falls into a black hole, he ends up inside the tesseract, where he can see and interact with different moments in Murph’s life. He uses this ability to send her important messages, like the coordinates that will help save humanity. The tesseract is created by advanced beings who exist in five dimensions, which means they can move through time easily.
The tesseract is also important because it helps explain some strange things that happen at the beginning of the movie. For example, books fall off Murph’s shelf, and a drone from India appears near Cooper’s farm. Some people think that Cooper accidentally caused these strange events when he was moving around inside the tesseract.
Overall, the tesseract is a key part of the movie’s story, allowing Cooper to travel through time and help his daughter, which ultimately helps save humanity.
The idea of the tesseract is based on a real geometric concept, but in the movie, it becomes much more than that—it’s a tool for time travel and communication across different dimensions. This concept is central to the movie’s themes of time, space, and the connection between people across different times and places.
The tesseract also raises interesting questions about who created it and how it works. The movie suggests that it was made by advanced beings who are actually humans from the future. This creates a kind of loop where the future humans help their past selves, which is a common theme in science fiction stories about time travel.
