Gravitational Time Dilation Formula
Quick fact
Time runs slower near massive objects, like Earth, compared to space—by about a millisecond per day.
Why this is interesting
Have you ever wondered why your GPS phone might gain seconds every day? It’s not a glitch—it’s gravity slowing down time.

Understanding Gravitational Time Dilation Formula
Imagine spacetime as a fabric. Massive objects bend it, and this curvature makes time flow more slowly in stronger gravitational fields. The formula quantifies how much time slows down based on the strength of gravity.
A deeper explanation
The gravitational time dilation formula is derived from Einstein’s general relativity. It shows that time passes slower near massive objects because spacetime curves around them. This effect becomes extreme near black holes, where time appears to stop for an outside observer.
