Thank you once again for the clarity of your thoughts. Esp. re: storage
requirements. Cool!
What little mind I have left has been boggled beyond belief. Since there
are roughly 10^32 (1 with 32 zeroes behind it) atoms in the universe (give
or take a few quatrillion) and if EACH was a supercomputer (ignoring of
course what they would be constructed of) and assuming a million, million
floating point ops per second capability (teraflops), and the universe
lasting another say 25 billion years (sorry , I am a bang/crunch
cyclist) -heat death would be 10 to 100 times that depending on who you talk
to-, and roughly 31.5 million seconds per year ... Well anyway I ran out of
fingers trying to figure this one out. It shows why NO human can really
comprehend large numbers or distances. We should just say BIGNUM for
anything over a milliom (OK billion).
But your analogy did help in one respect, I was worried that it would only
take a few trillion years. What a relief. ;>)
