Time Dilation: How Black Holes Warp Time

Time dilation occurs when gravity is so strong that time runs slower near massive objects.
Near a black hole, an outside observer sees clocks tick slower the closer they get to the event horizon.
To the person falling in, time feels completely normal—only outsiders notice the difference.
At the event horizon, time appears to freeze from an external perspective.
This effect was predicted by Einstein’s theory of general relativity.
The stronger the gravity, the greater the time dilation effect.
GPS satellites must account for weaker gravity in orbit, experiencing time slightly faster than on Earth.
In extreme cases near black holes, minutes for one observer could equal years for another far away.
Time dilation has been confirmed experimentally with atomic clocks at different altitudes on Earth.
Black holes show how space and time are woven together, stretching our sense of reality.
