The Physics That Makes Hearing Sound in Space IMPOSSIBLE

Most people hear explosions in every space movie and never stop to question it. The physics says those explosions are completely silent — and the reason they're silent reveals something extraordinary about the nature of sound itself. In this video, we explore what sound actually is at the molecular level, why it fundamentally cannot exist in a vacuum, and what that silence tells us about collective behavior in physics. Drawing from core ideas in The Feynman Lectures on Physics, particularly the treatment of waves, kinetic theory, and the behavior of gases, this lecture rebuilds your understanding of sound from scratch — from Robert Boyle's 1660 vacuum jar to the deepest note ever detected: a B-flat rumbling through a galaxy cluster 250 million light-years away, with an oscillation period of 10 million years. ⏱️ TIMESTAMPS: 00:00 — Every movie lied to you about this 02:15 — The invisible ocean you forgot you're swimming in 05:30 — What actually travels from a clap to your ear 10:00 — Robert Boyle's glass jar silenced a ticking watch 14:45 — 25,000,000,000,000,000,000 molecules in a sugar cube 19:20 — One lonely atom drifts for billions of miles 24:30 — Why the speed of sound formula breaks in a vacuum 29:00 — The dead-end search for the luminiferous aether 34:15 — What astronauts actually hear on spacewalks 38:40 — The deepest note in the universe: B-flat, 10 million year period 44:00 — Sound is not a thing — it's a behavior matter performs 49:30 — One water molecule is not wet, one air molecule is not loud 54:00 — The universe: the most dramatic silent movie ever made 📚 SOURCES: Richard P.
