Then during the early 1960s
Bullard and his associates used a computer to try to fit all of the continents together. Instead of using the shorelines, as other geophysicists had done, he used a depth of 914 meters (3000 ft) below sea level. This depth corresponds to about halfway between the

shoreline and the ocean basins and represents the true edge of the continents. By doing this he discovered a near perfect fit among the continents put together. With this discovery he helped further the idea of a supercontinent that an earlier geophysicist,

Bullard became one of the most important geophysicists of his day. He also did studies of the ocean floor, even though he suffered from seasickness and could rarely take scientific trips on the ocean. He was important to
