10 minutes from dinosaurs
[Fascinating breakdown of exactly how the asteroid that wiped out the dinosaurs hit, and how scientists figured that out](https://www.3quarksdaily.com/3quarksdaily/2017/08/ten-minutes-difference-that-doomed-the-dinosaurs.html). 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.
