Zero

 The concept of nothing.
The idea that you exist
Only here and now.
The notion 
That somewhere between now
And eternity
Is a space where something else could go.

We invented this idea
So many times.
The idea that there is a space
Where a number should go
But no real number to fill it.
Things go backward 
And forward,
But how do you show
That they're staying the same?

How do you demonstrate
The absence of something?

It is said that to reach 
This magical place,
We had to divide by infinity
And get rid of whatever we were holding onto.
But if that's the case, 
Than why can't you do the inverse
To get everything you could possibly want?
