Observer Time
--:--:--
An external observer, far from the black hole, experiences time in a familiar cadence.
Timefall: A Relativity Clock
Watch how time stretches as gravity bends spacetime—two perspectives, one cosmic moment.
Gravitational Time Dilation
Δt' = Δt × √(1 - gravityFactor)
gravityFactor ≈ 0.80
Strong gravity slows proper time for the traveler. To a distant observer, their clock lags behind.
Near the Singularity
--:--:--
Closer to the event horizon, time dilates and ticks crawl under intense gravitational pull.
Current factor: 0.80
Time Differential
Closer to a black hole, gravity slows time. Adjust the slider to see how 1 hour here compares to time far from the singularity.
1 hour near the singularity equals
