Sorry, there are about 10^80 subatomic particles in the universe, certainly much more than 10^70. These numbers correspond to 266 and 233 bits, respectively. I wonder if there aren't already more than 2^64 bits of computer storage (DRAM, SRAM, hard drives, floppies, CD-ROM's, Exabyte tapes, magtapes, dusty card decks, etc.) in the world already. Probably not, but if you include audio CD's, we're way up there. Does anyone want to hazard a guess as to the correct power of 2? -- -Colin
