What If the Asteroid That Killed the Dinosaurs Had Missed?

Sixty-six million years ago, a ten-kilometer asteroid struck Earth and wiped out every dinosaur that couldn't fly. But here's what almost nobody talks about: only about 13% of Earth's surface could have produced the sulfur cloud that caused a global mass extinction — and researchers who've modeled the impact say a difference of just a few minutes in arrival time would have sent that same asteroid into deep ocean instead. Regional disaster, not planetary catastrophe. Dinosaurs, in all likelihood, would still be here. This video traces the real science behind that near-miss: the 1980 discovery that first revealed the impact (the Alvarez iridium layer), the buried Chicxulub crater found hidden in decades-old oil survey data, why birds are technically surviving dinosaurs, and what might have happened if mammals had never gotten the empty planet they needed to eventually become us — including the strange possibility that an intelligent, large-brained dinosaur descendant could have evolved instead. You are not the result of evolution steadily building toward something. You're the result of a rock crossing the solar system for millions of years and arriving at almost exactly the wrong seven minutes.
