Random Sand Fact
How many grains of sand would it take to fill the entire universe?
The Greek mathematician Archimedes worked it out more than 2,000 years ago, in a work known as The Sand Reckoner. He calculated for the universe as people imagined it in his time.
The number system of his day could not handle numbers that large, so he invented his own way of writing them.
The answer was no more than 10⁶³ grains of sand. A one followed by 63 zeros.
Not infinite. Just very, very many.
