Black Hole Properties Calculator
Black Hole Properties
Calculate key properties of a non-rotating black hole including Schwarzschild radius, event horizon area, Hawking temperature, and evaporation time.
Formula
Rs = 2GM / c^2; Hawking Temperature = hbar x c^3 / (8 x pi x G x M x kB); Evaporation Time = 5120 x pi x G^2 x M^3 / (hbar x c^4)
Frequently Asked Questions
What is the Schwarzschild radius?
The Schwarzschild radius is the radius of the event horizon of a non-rotating black hole. Any object compressed within its Schwarzschild radius becomes a black hole from which nothing can escape.
What is Hawking radiation?
Hawking radiation is the theoretical thermal radiation emitted by black holes due to quantum effects near the event horizon. It causes black holes to slowly lose mass and eventually evaporate.
How long would a solar-mass black hole take to evaporate?
A black hole of one solar mass would take approximately 2 x 10^67 years to evaporate through Hawking radiation, vastly longer than the current age of the universe.
