10 minutes from dinosaurs

Fascinating breakdown of exactly how the asteroid that wiped out the dinosaurs hit, and how scientists figured that out. Notably, if the asteroid hit 150 miles away, it wouldn’t have caused gypsum to vaporize in the atmosphere, and most animal life worldwide (including dinosaurs) would have survived.

If the meteorite had arrived ten minutes earlier, or ten minutes later, it would still no doubt have inflicted devastation, but the dinosaurs would still be here and you wouldn’t.
