1 ^100 (1 followed by 100 zeros)
googol is the word a 9 year old boy came up with
(1938) when he was asked to say a word that
described the biggest number he could imagine
it wasn't known at the time but, coincidentally,
it is also how many years the universe lasts
a googol is a number so big that if you started
writing it down on paper (1 2 3 4 5 6 7 8 9 10 11 etc.)
there wouldn't be enough space in the universe to finish it
back in 1938 there wasn't anything known to
exist that needed a number that big
science now knows of things that exist
that makes a googol look like a fraction
