As a subject matter expert in comic book lore and the fictional universe of Superman, I can provide an explanation for Superman's ability to fly. Superman, a character from DC Comics, is an alien from the planet Krypton. His ability to fly is not a power that he possesses on his home planet, but rather, it is a result of Earth's yellow sun and its unique atmosphere.

In the comics, Superman's powers are derived from the radiation of Earth's yellow sun, which is similar to the light from Krypton's red sun. This yellow sun radiation gives him a range of superhuman abilities, including super strength, invulnerability, heat vision, and flight. The ability to fly is often depicted as a form of advanced levitation or defying gravity, which he can control at will.

The exact mechanism of how Superman flies is not scientifically explained within the comic books, as it is a fantastical element of the story. However, it is generally understood that his flight is a manifestation of his other powers, particularly his ability to manipulate and control the energy he absorbs from the sun.
