Why Can Humans Not Fly? A Hypothetical Study on Human Locomotion via Internal Digestive Events

Humans are biologically incapable of sustained flight; however, brief airborne movement, rotation, or unconventional locomotion may theoretically occur under specific internal conditions.

This paper proposes a speculative biomechanical framework in which internal digestive events (IDEs)—such as belching, flatulence, and sneezing—generate directional impulses that could be converted into rotational motion or short-term aerial displacement.

While clearly impractical in real-world conditions, this hypothesis aims to explore overlooked internal force vectors within the human body and to humorously challenge conventional assumptions regarding human locomotion.
