What if humans could fly?

What If Humans Could Fly? The Science Behind Why We Can't (And What It Would Actually Take) You've dreamed about it. Science has thoughts. Spoiler: it involves a 2-meter breastbone and chronic anemia. In this video, we break down the full science of what it would actually take for humans to fly — from the brutal physics of lift and wingspan, to the radical biological redesign your body would need, all the way to the neurological mutations that separate you from a pigeon. Then we ask the real question: what would the world even look like if we could? What you'll discover: → Why you'd need a 6.7-meter wingspan just to get off the ground → The terrifying skeletal and muscular changes a flying human would require → The genetic mutation in birds that humans simply don't have → How cities, warfare, real estate and privacy would be completely transformed → Why humans building airplanes is actually more impressive than evolving wings This isn't fantasy. This is science — with a sense of humor. If you're into hypothetical science, human biology, and thought experiments that make you question everything, subscribe and hit the bell.
