WebAny object with a physical radius smaller than its Schwarzschild radius will be a black hole. This quantity was first derived by Karl Schwarzschild in 1916: where RS is the Schwarzschild radius, G is the gravitational constant, M is the mass of the object and c is the speed of light. WebThe Planck length is the radius of the smallest black hole that (marginally) obeys the laws of general relativity. Note that if the black hole radius is R = ( ℏ G / c 3) 1 / 2, the black hole mass is obtained from R = 2 G M / c 2 i.e. M = c 2 / G ⋅ ( ℏ G / c 3) 1 / 2 = ( ℏ c / G) 1 / 2 which is the same thing as the Compton wavelength ...

In 1971, Hawking showed under general conditions that the total area of the event horizons of any collection of classical black holes can never decrease, even if they collide and merge. This result, now known as the second law of black hole mechanics, is remarkably similar to the second law of thermodynamics, which states that the total entropy of an isolated system can never decrease.
