![]() The Space Age and the Cold War surveillance technologies that were developed as a result were to bring the next great step in our understanding of our planet. ![]() Not only Paleomagnetism but also the fossil records support Wegener’s hypothesis of Continental Drift (Wiki) Even without the great advances in knowledge that the Space Age would bring, the theory had enough supporting data that opinions were starting to change, and in 1964, the Royal Society held a symposium on the subject. In the early 1950s, paleomagnetism was recognised a new (branch of) science and by early 1953, samples taken from India showed that the country had previously been in the Southern hemisphere as predicted by Wegener. When the German meteorologist, geologist and astronomer Alfred Wegener put forward his hypothesis of continental drift in 1912, such was our lack of knowledge about our own planet that half a century would pass before proof that would ultimately confirm it was found. ![]() It is perhaps hard to imagine, but only a little more than 50 years ago, the Ocean depths were in main completely unknown. Even after the last remaining “White Areas” on our maps of the Earth’s land masses had been filled in about a century ago, great discoveries that would change our perception of our planet were made as technology made them possible. Living on a constantly changing and evolving planet, unravelling the past is not an easy task as resurfacing, erosion and continental drift continuously eradicates what has gone before.
