"In 1858, when the first submarine cable was installed, sending a message across the Atlantic took nearly 18 hours." If anyone is curious as to why it took so long: https://en.wikipedia.org/wiki/Transatlantic_telegraph_cable TLDR: "smearing" of the signal (capacitance), no underwater amplifiers, very faint signal at the end. |
