Why ONE Scratch On Your Spacesuit Means Instant Death — Feynman's Warning

You've felt it your whole life and never noticed: 14.7 pounds of pressure pushing on every square inch of your body. Take it away, and you have 90 seconds. That's it. The difference between survival and death in space comes down to a garment thinner than a winter jacket — and a single scratch could be the end. In this video, we explore the terrifying physics behind spacesuit failure, inspired by Richard Feynman's relentless focus on thin safety margins and his famous conclusion from the Challenger investigation: "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." Drawing on Feynman's teaching approach, we build from a pot of boiling water to the Armstrong limit to the engineering miracle of 13 fabric layers that keep astronauts alive in the void. 📚 SOURCES: Richard P.
