Bad Math in a Math Thriller?

Rating: Null/10 (7 May 1999)

if you haven't seen it, 'Pi' is probably the first thriller about math ever made. the title character gets drawn into a weird confluence of computer self-awareness and jewish mysticism, centered around one 216-digit number that represents (in hebrew characters) the true name of god. the gist is, when the high rabbi speaks the name in a ceremony within the holy of holies, the world is set right and the messianic age comes closer, or some such vague happy outcome.
now for the most part, it was a creepy and effective movie, full of migraines and hallucinations... and math. i guess it was intended to impress non-math-geeks, but even only semi-math-literate viewers should have caught this egregious slip-up... late in the movie, our protagonist says to the assembled rabbis who are begging him to cough up the 216-digit magic number, "i'm sure you guys have tried out all the 216-letter words, right? spoken them aloud and nothing happened, right?"
uh-huh. ok, let's ignore the fact that only the first ten characters of the hebrew alphabet can be represented by single digits (thereafter the characters have values of 20, 30, etc). let's assume that only one out of every million of the resulting 216-letter words is pronounceable, and that some computer program has already weeded out the unpronounceable ones. let's assume that you can pronounce a 216-letter hebrew word in one second. let's assume that every one of six billion human beings on earth was actively working through the permutations, without sleep, 24/7. let's assume, by virtue of murphy's law, that the name of god is the absolute last 216-letter word pronounced. this whole process would take approximately 1.13 x 10 to the 192 power years, or 5.7 x 10 to the 181 power *times the supposed age of the universe*. that's 57,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,0 00,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,0 00,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,0 00,000,000,000 times the age of the universe.
not the kind of gaffe a number theorist is likely to make.
