What would happen if a small asteroid moving at 30,000 miles an hour slammed into Earth? In this video, Mark Boslough, a theoretical physicist at Sandia National Laboratories, demonstrates how, even if the asteroid exploded high in the atmosphere, temperatures at the ground beneath would be as hot as the surface of the sun, and wind speeds of the resulting searing gas would be beyond hurricane force. "This is one of the most extreme events, I think, that could ever happen on the surface of the Earth," Boslough says, likening it to a white-hot tornado.
