The men who have learned as much as we know about the universe point out that the sun is an insignificant, moderately hot star in a nebula where it is fixed. The Milky Way, which I have always wanted to spell "w-h-e-y," is composed of our brothers and sisters, and we are all moving around a central hub. And the hub is moving toward some place, I don't know where. My brothers and sisters are numbered in billions of billions, and our galaxy itself is one of many, many--how many, I don't know.
Our sun is so small and our earth, its offspring, is so tiny that when I think of the magnitude, I think of what O. Henry described as a "Statue of What's the Use."
What difference does it make that I exist? What possible influence can I make, or my nation make, or a world make?
