I find it interesting that we actually know the size of a bit ;-) From: <http://www.sciam.com/article.cfm?articleID=000D6E85-2E76-1F0C-97AE80A84 189EEDF>:
Planck area, approximately 10^(-66) square centimeter, is the fundamental quantum unit of area determined by the strength of gravity, the speed of light and the size of quanta...it is as if the entropy were written on the event horizon, with each bit (each digital 1 or 0) corresponding to four Planck areas. I read this as the entire AES256 lookup-table (plaintext/ciphertext pair and matching 256 bit key) only takes about 2400 square kilometers (assuming I did my arithmetic correctly). The Larsen B ice shelf lost this much area between 1998 and 2000. Dang, we could have used that.
