In a book, *The Unimaginable Mathematics of Borges' Library of Babel*, the author reminds us that just 10 to the 100th power "grains of sand would completely fill 10 billion universes the size of our own."

To reference the number of books a Universal Library would contain, the book I am reading is Volume 13 to the 2600th power of *The True History of the Periodic Universe*.

That's a lot of universes to fill.
