Starting from theorems proved by Stephen Hawking, Jacob Bekenstein conjectured that the black hole entropy was proportional to the area of its event horizon divided by the Planck area.

where where k is Boltzmann's constant, and
is the Planck length.
The black hole entropy is proportional to its area A. The fact that the black hole entropy is also the maximal entropy that can be squeezed within a fixed volume was the main observation that led to the holographic principle

I found this interesting and agreeable to the overall concept, that a black holes stability is based upon the surface area.
Although, what I have been reading is that for a black hole, a smaller surface area provides a greater rate of emission than a larger surface. This tends to go against the expectations of the theory. However I read over some issues that have not been solved, and I wonder what kind of results would be produced if the surface area was greatly bloated.
