Green Bank, West Virginia, is a tech-savvy teenager’s nightmare. In this tiny town in Pocahontas County-population 143-wireless signals are illegal. No cell phones. No WiFi. No radio. No Bluetooth. No electronic transmitters at all. You’re not even allowed to cozy up to an electric blanket.
The remote town is smack in the center of the National Radio Quiet Zone, a 13,000 square mile stretch of land designated by the FCC to protect two government radio telescopes from man-made interference. The rules, though, are most strict in Green Bank’s neck of the woods. So strict, actually, that a policeman roves the streets listening for verboten wireless signals.
It’s necessary, though. The town is home to the Green Bank Telescope, the largest steerable radio telescope in the world-and arguably our most powerful link to the cosmos. Scientists there listen to radio energy that has journeyed light years, unlocking secrets about how the stars and galaxies formed. A rogue radio signal could prevent potential discoveries, discoveries that could answer big questions about how the universe ticks.
