What Really Carries Your Words Across an Ocean

At this moment, your messages are lying at the bottom of the ocean. Send a text to another continent and it does not, whatever the films have suggested, ascend to a satellite. It dives. Nearly all traffic between continents travels through cables resting on the sea floor, past shipwrecks and deep sea trenches, in a darkness that never lifts.

U ovom trenutku, tvoje poruke leže na dnu oceana. Pošalji poruku na drugi kontinent i ona se, unatoč onome što filmovi sugeriraju, ne penje do satelita. Ona zaranja. Gotovo sav promet između kontinenata putuje kroz kabele koji leže na dnu mora, pokraj olupina brodova i dubokih oceanskih jaraka, u tami koja se nikada ne podiže.

Each cable is remarkably modest, often no thicker than a garden hose. Within it, shielded by layers of steel and plastic, run slender glass fibres that carry your words as pulses of light. Specialised ships lay these cables slowly across entire oceans, and the routes are plotted the way roads are plotted: around underwater mountains, clear of fishing grounds, away from any seabed inclined to shift.

Svaki je kabel iznenađujuće skroman, često ne deblji od vrtnog crijeva. Unutar njega, zaštićena slojevima čelika i plastike, protežu se tanka staklena vlakna koja tvoje riječi nose kao svjetlosne impulse. Specijalizirani brodovi polažu te kabele polako preko čitavih oceana, a rute se planiraju kao što se planiraju ceste: oko podvodnih planina, dalje od ribolovnih područja, dalje od svakog morskog dna sklonog pomicanju.

The system's enemies, it turns out, are not spies but sharks and ship anchors. Cables get bitten, snagged and buried, and when one breaks, a repair ship sails out, hooks it off the seabed, hauls it aboard, and splices the glass back together in a floating workshop. So tonight, when you message someone on the far side of an ocean, consider the journey your words are about to make: a flash of light travelling the length of an ocean floor, inside a thread of glass.

Ispada da neprijatelji ovog sustava nisu špijuni, nego psi morski i sidra brodova. Kabele grizu, zapinju o njih i zatrpavaju ih, a kada se koji prekine, brod za popravke isplovi, izvuče ga s morskog dna, izvadi na palubu i spoji staklo natrag u plutajućoj radionici. Zato, večeras, kada nekome pošalješ poruku na suprotnu stranu oceana, razmisli o putovanju koje tvoje riječi upravo kreću: bljesak svjetlosti koji putuje duž morskog dna, unutar niti od stakla.
