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?
