The cells in my fingernails contain atoms enough
Their own whirling systems
To form ordered constellations in layered universes....

Space between solids goes down and down and down...,
Around us mostly nothingness
Down and in and down and in....
On and on and on.

Do we need to look outward
For outer space?

Didn't Robert Burns tell us that fleas have fleas and fleas have fleas, and fleas have fleas that bite 'em?

Infinity runs hard both ways.
