Whether you walk over buried fiber optics or drive a car across them,
above-ground activity creates a characteristic vibration that ever-so-slightly disturbs the way light travels through the cables.
With the right equipment, scientists can parse that disturbance to identify what the source was and when exactly it was roaming there.
