This is a FANTASTIC simulation of a large asteroid crashing into the earth. Time-stamp breakdown: 0:12 An asteroid with a diameter of 500 km. 0:47 Destination: The Pacific Ocean. 1:17 The impact peels the 10 km crust off the surface. 1:28 The shockwave travels at hypersonic speeds. 1:53 Debris is blasted across into low Earth orbit, 2:11 and returns to destroy the surface of the Earth. 2:55 The firestorm encircles the Earth, 3:05 vaporizing all life in its way. 3:34 Within one day, the surface of the Earth is uninhabitable. 4:19 The evidence shows that this has happened at least six times in Earth's history.
