Scientists have explained much of the universe as “dark matter,” and they have learned about “black holes” at the centers of galaxies. Astronomers have used the Hubble Space Telescope to examine objects as much as billions and trillions of light years distant in space, or, in other words, objects as they appeared near the time of the origin of the universe as we know it. Despite these advances, the speaker of “The Iceberg Seven-eighths under” states that “We know incredibly much and incredibly little” (line 2). There is so much to know that still “goes secret, sunken, nigh-submerged” (line 10). The invisible part of the iceberg thus is an apt metaphor for the status of human knowledge about the inscrutable extent of the universe. There is indeed a paradox.
