Something Happens To You In Space

There are no sounds in space. So why have astronauts heard them? From mysterious knocking sounds aboard orbiting spacecraft to cosmic rays flashing through human vision, space changes the body and mind in ways most people never realize. Astronauts have reported strange audio, visual distortions, sensory confusion, and profound psychological shifts while drifting beyond Earth. Here, we explore the real science and unsettling experiences behind spaceflight, including Yang Liwei’s unexplained knocking sounds in orbit, the eerie “space music” heard during Apollo 10, cosmic radiation striking the human retina, space adaptation syndrome, and the psychological phenomenon known as the Overview Effect. Some anomalies have explanations. Others remain uncertain. The deeper humans travel into space, the more we confront a difficult reality: our brains were never built for the void.
