High above the Earth, thirty-one atomic clocks tick in quiet defiance of intuition — running faster than any clock on the ground, not through error, but through the precise operation of laws Einstein described a century ago. The Global Positioning System, built to guide ships and drivers, cannot function without accounting for the warping of spacetime itself: a 38-microsecond daily drift that, left uncorrected, would scatter your location across a small country by nightfall. What began as an engineering problem became an ongoing proof that the universe behaves exactly as one man predicted it w

Consumers experience no direct impact as GPS corrections are already embedded in satellite hardware. However, any failure in relativistic corrections would severely disrupt navigation services, ride-sharing, delivery systems, and location-based services that billions depend on daily.
Highlights critical infrastructure vulnerability and the importance of maintaining GPS system integrity. May inform policy discussions around space infrastructure investment, satellite maintenance standards, and redundancy requirements for essential navigation systems. Demonstrates need for continued funding of fundamental physics research that underpins modern technology.
