9. The Time Travel Paradox
Another huge plot hole in Interstellar is – ignoring the time travel paradox yet again. It’s been overdone in so many movies, it’s not even funny! So the time travel paradox states that it will not work if your present self cannot be saved without the help from your future self. A casual loop is caused in this case. That means there is no way Cooper could have played the Space ghost from behind the haunted bookshelf in Murph’s room.
