What it calculates
The “Black Hole Time Dilation” calculator computes Time at observer in min from 3 parameters: r (dist. from center, km), schwarzschild radius, km, time at distant observer.
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters r (dist. from center, km) = 100, Schwarzschild radius, km = 30, Time at distant observer = 60 the result is 50.2 min (τ = T·√(1 − r_s/r)).
How to use
- Enter r (dist. from center, km), schwarzschild radius, km and time at distant observer — each field above is adjustable with a slider.
- Time at observer (min) is calculated automatically as you type.
