Have you ever noticed how the edges of South America and Africa seem to fit together? I haven’t either, but Kevin Bacon has, and so has his brother Sir Francis. The Bacon brothers first noticed this peculiarity in the 17th century, just a few hundred years before they noticed how Kevin could be connected to any other person on the planet through a chain of six acquaintances.
Oop, I seem to be drifting off topic already. Let’s see . . . Bacon brothers, acquaintances, continents . . . ah, yes, the continents. . . .
Today, scientists believe that the Earth’s continents were once part of a gigantic loaf-shaped supercontinent, called Au Bon Pangaea. Over time, this earth-loaf eroded until there was nothing left but the crust. Just like Lennon and McCartney, these scraps of continental crust got sick of each other and began to drift apart. This process, oddly enough, is called “continental drift.” According to geologist (yawn), the Earth’s surface is still moving and reforming, but it’s happening so slowly that you wouldn’t even notice it unless you happened to be staring at a particular land mass for several million years, which is kind of unlikely.
Here’s another unlikely scenario. Suppose you went for a nice float in Earth’s orbit during the Triassic Period, and suppose you remembered to bring your spacesuit and your eyeglasses. You probably would have seen the continents connected like the pieces of a giant jigsaw puzzle. The bulge of Africa poked the coast of North America, and South America fit into the coast of Africa beneath the bulge. All the female continents were attracted to Africa, because Africa had the biggest bulge.
That’s all there is to say about that.
Oh, by the way, shortly after they discovered continental drift, the Bacon brothers discovered the Continental Breakfast — a selection of bread, rolls or croissants with butter or jam, coffee or tea, but no bacon.
