And we gained a pretty damn good idea during World War 2 when we were trying to map parts of the ocean floor for submarine warfare purposes, and discovered the mid ocean fault points. Especially the Mariana Trench, which is spang in the middle of the Atlantic between the jigsaw puzzle coastlines of Africa and South America.

Needless to say we weren’t to keen to blab to our enemies just how much we knew about the seafloor, and neither were they. What with submarine warfare being a Big Deal in the cold war following, and all.

Maybe I’m not understanding you, but the Mariana Trench is in the Pacific Ocean.

  No, I’m wrong. It’s the Mid-Atlantic ridge.

  Yeah, it drifted there since the 40s.

    Some people just don’t watch the news. 🙄 Marianas Trench relocated off the coast of North Carolina back in like 2020.

I have to believe that as soon as there were accurate maps of South America’s east coast and Africa’s west coast, someone must have looked at them and said – you know, I bet those two were joined at some point in the past.
