Grain of Sand

"All the world in a grain of sand; all the universe too. "

It is commonly known that no matter how big something is, there will always be something bigger.  That is, we think of infinity as being very, very big.

But do we think about how small something is, there will always be something smaller?  That is, we can never get to the smallest thing; everything is divisible?  

Infinity goes both ways.

One thing is always infinitely bigger than nothing.

To create infinity, all that has to be done is to create a grain of sand.
