Google Maps and GPS use Einstein’s two laws of relativity to accurately track time and location. Special relativity states that satellite clocks moving at high speeds will slow down, while general relativity shows that weaker gravity causes clocks to speed up. This results in a 38-microsecond difference per day, crucial for precise navigation.
