Asteroid Winter and Dinosaur Extinction

Dinosaurs didn't just vanish overnight. The asteroid that wiped them out created a chain reaction

most people never learn about. When it struck, the impact was equivalent to billions of atomic

bombs, instantly vaporizing rock and sending debris into the atmosphere.

This blocked out the sun for years, dropping global temperatures by twenty degrees.

Plants died first, then herbivores starved, and finally carnivores had nothing left

to hunt. The entire food chain collapsed in less than a decade. Only small mammals

hiding underground survived to eventually evolve into us.
