So, if you want network signals, hit the floor, literally. The internet consists of tiny bits of code that move around the world, traveling along wires as thin as a strand of hair strung across the ocean floor. The process for laying submarine cables hasn’t changed much in 150 years — a ship traverses the ocean, slowly unspooling a cable that sinks to the ocean floor. The cables are unwound from the back of a ship, sink to the ocean floor, and the world is connected in speeds measured in milliseconds. The submarine cables map shows economic connections in less-developed countries as well.
