Assume the surface area of the event horizon of an ordinary black hole is 1050, ordinary meaning uncharged and nonrotating. The hole glows with Hawking radiation----what is the radiant power? I gave the event horizon area in natural units but it's easy to convert to square meters if you wish it that way. The area 1050 is 2.6 x 10-20 square meters, or 2.6 square angstroms. In natural units (c=G=hbar=k=1) the radiant power of a BH with area A is simply 1/960A So having the area 1050 means that the luminosity is essentially 10-53. To which of the four wattage figures given in the poll is this equivalent?
