When you click on a video or send a message from the other side of the world, do you think the data reaches you from an invisible cloud? Absolutely not! Every pixel on your screen reaches you through glass strands as thin as a human hair, lying in the pitch darkness of the deepest parts of the ocean.

99% of global data traffic is not carried by satellites as commonly believed; it's carried by a massive 1.4 million kilometer network of fiber optic cables laid on the ocean floor, long enough to circle the Earth 35 times.

So how are these delicate cables protected from the freezing temperatures at the bottom of the ocean, tectonic earthquakes, ship anchors, and even sharks? How do cable-laying ships place thousands of kilometers of lines on the seabed? How is an entire country's internet saved when a cable breaks? Discover the billion-dollar struggle of giants like Google, Meta, and Amazon on the ocean floor and the physical backbone of the digital universe in this video!
