Gravitational Time Dilation

Quick fact

Even on Earth, clocks at higher altitudes gain about 45 microseconds per day compared to clocks at sea level, a measurable effect of gravitational time dilation.

Why this is interesting

Have you ever wondered why time seems to flow differently near a massive object? Gravitational time dilation, predicted by Einstein's general relativity, means that clocks tick slower closer to a source of gravity.
