7. GPS Satellites and Time Correction

Time dilation isn’t just for astronauts—it affects the technology we rely on every day. GPS satellites orbit Earth at high speeds and experience weaker gravity, which causes their clocks to tick differently than those on the ground. Without constant adjustments, GPS calculations would quickly become inaccurate. This real-world challenge is solved by applying Einstein’s relativity, keeping navigation systems precise.
