Hawking's equations for black hole energy, power, and evaporation time are unattractive. http://en.wikipedia.org/wiki/Hawking_radiation
The energy equation, with its denominator of 8 pi GM, isn't too bad, but it has already been challenged as being off by a factor of two. See arxiv, "Black Hole Thermodynamics and the Factor of 2 Problem"
The power equation is just plain ugly, with "15360 pi " in the denominator. I don't think there is any other cosmological equation that looks so wrong.
The evaporation time appears ugly too, with a "5120 pi" in its denominator.
Given that the energy equation is possibly wrong, simply transferring that correction through the power and evaporation equation reduces their awkwardness, but the problem remains that these equations are anything but elegant, and elegance appears to be a rule in physics and cosmology. Consider how simple and elegant the Planck relation is.
Do any of you have ideas or opinions on this? Do you people believe these equations are correct? There is no experimental confirmation for them. And if the energy equation is wrong, the others are too.
