How does the internet really work? I talk about the physical side of the internet that's hidden from view: undersea cables thinner than a garden hose, data centers consuming the energy of small cities, and pulses of light in fiberglass. We go back to the first transatlantic telegraph in 1858, through the birth of the ARPANET and Charley Kline's two-letter message, all the way to low-orbit satellite constellations. We explain how DNS works, what the BGP protocol is, and why Charles Kao won a Nobel Prize for fiber optics. We also examine what the quantum internet could change. In this episode, we go through these facts calmly, chapter by chapter. 🧩 SERIES: 100 Facts for Sleep ⏱ CHAPTERS: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 Chapter 7 Chapter 8 Chapter 9 Chapter 10 📖 KEY REFERENCES: Liao, S.-K., Cai, W.-Q., Liu, W.-Y., et al.
