seanahan Actually, mathematically speaking, you can view this number as tiny. Now Skewes number, that's freaking huge. Feb 26, 2008
thesuperiorbeing Why thank you, gangerh. And great pun! Feb 24, 2008
gangerh Great googolplexplanation, TSB. Feb 24, 2008
thesuperiorbeing You see, Googol is a number with one hundred zero's (you know, a million has 6 zero's a hundred has 2... well this one has 100). But Googolplex is a number with GOOGOL zero's. Also, if you tried to write googolplex down (the number, not the word), - even if each digit was the size of an ATOM - then it wouldn't fit inside the UNIVERSE. Impressive, eh? Feb 23, 2008
