Asteroid Impact and Effects

The video describes the catastrophic impact of a 500 km diameter asteroid on Earth, targeting the Pacific Ocean. The impact peels off the Earth's crust, sending shockwaves at hypersonic speeds and blasting debris into low Earth orbit. This debris returns to further devastate the planet, while a firestorm encircles the globe, vaporizing all life. Within a day, Earth becomes uninhabitable. Such events have occurred at least six times in Earth's history.
