What Would Happen If an Asteroid Hit the Ocean?

You're on a beach, and 300 miles out over the Atlantic, the sky flashes. An asteroid two thirds of a mile wide has just hit the ocean. So what happens next? Do you have time to run? The answer is stranger than Hollywood thinks: almost none of the impact energy becomes waves, the ocean first opens a hole miles wide, the ground shakes a minute later, the boom arrives after 24 minutes, and the wave needs about 40. Scientists still argue about how big it would be. Then we scale it up, from the Chelyabinsk meteor to the dinosaur-killing Chicxulub impact and its mile-high tsunami, look at the real deep-ocean impact Eltanin, NASA's DART mission, and the asteroid Apophis, which will fly past Earth on Friday, April 13, 2029.
