Recently I learned that the entropy of a black hole is the black hole's surface area in disguise. Since according to the second law of thermodynamics, entropy must always increases, so a black hole's surface area must always increase as well. But according to the Hawking radiation, black hole can lose energy or mass, thus surface area as well, because of the negative energy density around it. So this means that entropy would decrease. Wouldn't that violate the second law of thermodynamics?
