你的信息正在海底旅行

此刻，你发出的信息正在海底。给另一个大陆发一条短信，它并不会像电影里演的那样飞向卫星，而是潜入海底。几乎所有跨大陆的通信都要经过铺在海床上的电缆，途经沉船和深海海沟，穿过永远漆黑的深处。把这条信息发给那个你经常隔着海洋联系的人。

Right now, your messages are at the bottom of the ocean. Send a text to another continent and it does not fly up to a satellite, whatever the films have taught you. It dives. Almost all traffic between continents travels through cables lying on the sea floor, past shipwrecks and deep sea trenches, in the permanent dark. Send this to the person you message across an ocean.

每一根电缆其实并不起眼，粗细往往和一条花园浇水管差不多。内部由层层钢材和塑料保护着，里面是细细的玻璃纤维，你的文字就化作一道道光，沿着它们传送。专门的船只会缓慢地把电缆铺设过整片海洋，航线的规划方式和修路一样：绕开海底山脉，避开渔场，躲开海床容易移动的地方。

Each cable is surprisingly modest, often about as thick as a garden hose. Inside, protected by layers of steel and plastic, run thin glass fibers that carry your words as flashes of light. Special ships lay them slowly across entire oceans, and the routes are planned the way roads are planned, around underwater mountains, away from fishing grounds, avoiding places where the seabed likes to move.

这个系统也有天敌，而最顽固的敌人不是间谍，而是鲨鱼和船锚。电缆会被咬破、被缠住、被掩埋，一旦断裂，维修船就会出海，把电缆从海床上钩起、拉出水面，在一座漂浮的“工作室”里把玻璃纤维重新接好。所以今晚，当你给远方的人发消息时，不妨想象一下这段旅程：你的文字刚刚以一道光的形式，穿过了一整片海底。

The system has enemies, and the most persistent ones are not spies but sharks and ship anchors. Cables get bitten, snagged and buried, and when one breaks, a repair ship sails out, hooks the cable off the seabed, hauls it up and splices the glass back together in a floating workshop. So tonight, when you message someone far away, picture the journey. Your words just crossed an ocean floor, as a flash of light in a glass thread.
