1 ^100 (1 followed by 100 zeroes)

a 9 year old boy came up with the word googol

in 1938 when he was asked to say a word that

described the biggest number he could imagine

it wasn' known at the 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

or...

it's how long it would take to move the universe

from one place to another moving one atom a year

and then when that's done doing it again another

1 000 000 000 000 000 000 000 000 000 000 000

000 000 000 000 times

there weren't any real values back in 1938 that

needed a number that big

since then there are real values that have come to

be known that make a googol look like a fraction
