The glass fibers connecting our wireless world

All modern means of communication rely on glass. From the Gorilla glass on our phones to the infotainment screens on our cars. But when I think of the internet I think of 5G, Starlink satellites, and WiFi, and I never think about the 750,000 miles of fiber optic cables currently running under our oceans: the tiny strands of glass that carry all of our photos, emails, and video chats. It is through these hair-thin strands of fiber that we are able to instantly communicate to almost anyone, anywhere, and it all relies on a 5,000-year-old technology: glass.
