Thanks for the link, Bill. Fascinating. I love big numbers!

Black holes will have all evaporated after 10^100 yrs?...that's about 730 thousand trillion trillion trillion trillion trillion trillion trillion times the current age of the Big Bang universe. I wonder if some form of intelligent life could exist during that time, until thermodynamic equilibrium. I like to imagine so. It's life processes could well afford to be on the slow side.
