Asteroid that led to dinosaur extinction impacted Earth at ‘deadliest possible angle’: study

The video discusses the extinction of dinosaurs 66 million years ago, attributed to an asteroid impact. Researchers used geological data from the Chicxulub Crater in Mexico to model the asteroid's impact angle, which was calculated at 60 degrees. This steep angle caused carbonates and water to be ejected into the atmosphere, triggering a nuclear winter that led to the extinction. The study found asymmetries in the crater's structure, supporting the deadly impact angle theory.
