This was so lovely. It’s denser than Chambers’ Monk and Robot books, and quite scientific, but it’s such a rich, if brief, examination of space travel, science, and the “why” questions we have about the universe. It touches on deeply human emotion and concerns and finds reverent joy in the unknown as much as it explores the feeling of isolation and encroaching emptiness the unknown also brings with it. A really wonderful piece of work that will keep you thinking for a long time, but also leave you a bit smarter than when you started. At least, I did. Truly a love letter to the universe and to exploration.
