Foundation

Foundation is set in the far future, when humanity has expanded into a vast galactic empire. A mathematician comes forward to announce that he's crunched the numbers — and found that the empire is on the verge of collapse, and humanity is about to enter a 30,000 year dark age. The Apple TV+ series is based on a series of books by Isaac Asimov that was once awarded a Hugo Award for best science-fiction series of all time.
