This one-hour special takes a scientific look at Superman. He’s the ultimate superhero. But how much of his science fiction universe makes sense when judged by the laws of science fact? In this hour, travel to the fictional Metropolis, Krypton and beyond, as images from Superman comics, TV shows and films–including highlights from the 2006 blockbuster Superman Returns–are used by scientists, artists and filmmakers to explore the real-life science that helps explain the Man of Steel’s super-powers.
