The National Radio Quiet Zone covers 13,000 square miles of the Allegheny Mountains, and within it, wireless signals are heavily restricted or banned. No cell towers. No WiFi in many areas. Microwave ovens must be shielded. All to protect the Green Bank Observatory, home to the world's largest fully steerable radio telescope, listening for signals so faint that a cell phone on Mars would drown them out. The telescope searches for pulsars, studies the formation of galaxies, and participates in SETI - the search for extraterrestrial intelligence. To hear the universe, the universe must be quiet. The Quiet Zone has attracted an unexpected population: 'electrosensitives' who believe wireless signals cause them physical harm. In Green Bank, they've found refuge. The town has become equal parts astronomical research station and sanctuary from the electromagnetic world.
