There ought to be something very special about the boundary conditions of the universe and what can be more special than that there is no boundary?

If I have questions about the universe on my mind when I go to bed, I can't turn off. I dream equations all night.

A person who smiles in the face of adversity...probably has a scapegoat.

The boundary condition of the universe is that it has no boundary.
