Book excerpt: The concept of time is mind-bending, fascinating, liberating, terrifying and inevitable. In astronomy, time is also distance. Everything we see is already an image of the past, and the further we look, the older the images. In this poetry collection, time gives us fascinating insights into the past. The capability for temporal evolution, for change, is liberating. Our limited supply of time is terrifying. Yet time is inevitable - an ultimate law of nature that we all must obey.
