You couldn't fill a 128-bit storage pool without > boiling the oceans. An technical facility with an diameter of 1 centimeter could store 10 ^ 66 bits. The maximal capability is limited by the entropy of the system, the whole visible universe has an entropy of 10 ^ 100 bits. The absolute border is the holographic border, a system increasing information storage over the holographic border will turn into a black hole. (see also Three Roads to Quantum Gravity, Von Lee Simolin, Basic Books, 2002) This may be stuff for an fortune ;) -- /\/\ichael Ranner mranner@inode.at - mranner@jawa.at - mranner@bugat.at ----------------------------------------------------- BSD Usergroup Austria - http://www.bugat.at/ -----BEGIN GEEK CODE BLOCK----- GIT/CS/AT dx(-) s+:(++:) a- C++ UBLVS++++$ P++>+++$ L-(+)$ E--- W+++$ N+(++) o-- K- w--()$ O-(--) M@ V-(--) PS+>++ PE(-) Y+ PGP(-) t+ 5+ X+++(++++) R* tv++ b+(++) DI++ D-(--) G- e h--(*) r++ y? ------END GEEK CODE BLOCK------
