In January of 1973, Bardeen, Carter, and Hawking published their “four laws of black hole mechanics.”
There was a zeroth law which, as is often the case with zeroth laws, you need not worry about.
The First Law related the change in a black hole's internal energy to changes in its area, angular momentum, and charge. The Second Law was Hawking’s area theorem. And the Third Law said a black hole can’t reach zero surface gravity through any physical process.
