What Is Black Hole Time Dilation?
Black hole time dilation is the slowing of time in a strong gravitational field. The closer you get to a black hole, the more slowly time passes relative to a distant observer.
How Gravity Affects Time
General relativity describes gravity as curved spacetime. Stronger curvature changes how clocks tick, so gravity near a black hole can stretch time dramatically.
How the Calculator Works
Choose a black hole scenario and compare the clock near the gravity well with a clock far away. The result gives a simple estimate of gravitational time dilation for that setup.
Example Scenarios
A light gravitational field produces only a small offset, while a very compact, massive black hole produces a much larger difference between the two clocks.
Limits of the Model
This is a simplified educational model. Real black hole environments can involve spin, accretion disks, orbital motion, and other effects that make exact calculations more complex.
Frequently Asked Questions
Why does time slow near a black hole?
Because gravity curves spacetime more strongly, and that changes the rate at which clocks tick.
How is black hole time dilation calculated?
A simplified calculator uses the gravitational time dilation equations from general relativity.
Is this a real physical effect?
Yes. Gravitational time dilation is a real prediction of general relativity.
What happens near the event horizon?
Time appears to slow dramatically for a distant observer, and the simplified model approaches its limits there.
