What are the similarities between the Hubble Space Telescope and a poem. The obvious answer is none. No similarities. One is a complex scientific instrument made of metal and silicon letting us see far into the cosmos. The other is a form of literature, made of words, showing us whatever the poet sees in the particular way she or he sees it. The telescope looks into deep outer space. The poem looks deeply into a different space, not inner or outer but human space, the space within the heart and mind and the space between the mind and what is minded with imagination.
Maybe there is a similarity after all.
