How many grains of sand would it take to fill the entire universe?

Archimedes asked that question more than 2,000 years ago. In The Sand Reckoner, the Greek mathematician set out to show that even a number that enormous could be expressed.

The number system of his time was not enough, so he developed a way to write vastly larger numbers. His calculation reached roughly 10⁶⁴ grains of sand.

Not infinite. Just very, very many.

P.S. Every AKIN piece holds sand from more than 220 locations. How many grains? Unclear.
