How an Underwater Bomb in Australia Was Heard Around the World

gizmodo.com - In 1960, scientists did one of those experiments that just aren't allowed anymore. For the sake of science, they blew up three 3oo-lb anti-submarine bombs off the coast of Australia. A listening station 10,000 miles away in Bermuda—on the exact other side of the planet—waited. And waited. And, about three and a half hours later, they saw the blip that confirmed their hypothesis: Yes, sound in the ocean really can travel across the world.
