Unveiling the Deadly Impact: How Dust from an Asteroid Led to the Extinction of Dinosaurs
TL;DR Summary
Computer simulations suggest that the dust kicked up by the asteroid impact that wiped out the dinosaurs played a crucial role in their extinction. The impact in Chicxulub, Mexico, 66 million years ago caused widespread devastation, but the exact mechanisms of the extinction event have remained unclear. Researchers in Belgium argue that the role of trillions of tonnes of dust in blocking out the sun and disrupting photosynthesis has been underestimated. Simulations show that the dust could have remained in the atmosphere for up to 15 years, causing a global winter and devastating effects on vegetation and the animals it supported.
