State of Mind

In my recent state of mind I sense the world is flat. With slight steps I'll creep to the earth's edge and peer downward to gaze the tops of stars, galaxies, and the luminous gases that swirl 'round heavenly black holes. Scions of Newton, Einstein, Galileo, and Copernicus beware: don't stagger too near the edge, nor slip drunkenly into the great Milky Way.
