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?
