Description

Here is the transcribed text from the comic:

Top panel: "Look! This vein of silica forms a naturally occurring piece of optical fiber. If you put something on it, you can see its image at the other end, 40 meters away!"

Middle panel: "I wonder what strange magic the ancient people thought it held…"

Bottom panel: "50,000 years earlier…" "Okay, stand right there for a second. I need to go grab something."
