The end Cretaceous asteroid impact released an extraordinary amount of energy, with scientific estimates on the order of tens of millions to about one hundred million megatons of TNT. The collision generated massive tsunamis and lofted vast quantities of dust and sulfur bearing material high into the atmosphere, while global wildfires added soot. Climate models show that this combination sharply reduced sunlight, shut down photosynthesis, and drove severe global cooling for months to years, coll

Did you know all dinosaurs went extinct when Earth got hit by an asteroid? APRIL FOOLS! It might be shocking to hear, but the asteroid that killed the dinosaurs didn’t finish the job. ☄️ The asteroid, or the K-T extinction event, that happened 65 million years ago wiped out about 80 percent of all plant and animal life on the planet. 🌳🦕 The effects of the asteroid and the winter fallout that occurred afterward killed all tetrapods (four-legged animals) that weighed over 50 pounds. 🦖 However,

Forget the asteroid! Today we're exploring how flat-earthers believe dinosaurs met their demise. Many subscribe to familiar extinction events, like a giant impact, but with a flat-earth twist! Imagine a comet hurtling towards our plane-like world. Where would it land? Stay tuned to see how flat-earthers explain dino extinction in a world without gravity or a curved surface. #FlatEarth #Dinosaurs #AlternateHistory 🦖😂 #space #astronomy #funny #asteroid #cosmos #spacescience #science | Space Scie
