This is it. The final part. The universe is about to end, and every person left alive knows it. The planet He is racing toward the metagalactic center, the exact point where everything started and where everything will finish. There are no more tricks left, no more political games. Just the countdown.
The chapter title is “Object 4001-Alephnull.” If you’re not a math person, aleph-null is the smallest infinity. It’s the number mathematicians use when they need to count things that never stop. That’s what this chapter is about. Building something at the edge of what’s countable, what’s knowable, and sending it into a place that shouldn’t exist.
These two chapters shift the whole book. Up until now, “The Triumph of Time” was about scientists doing math and old people worrying about the end of the universe. Chapters 4 and 5 bring in two things that make it personal: alien children who are better at life than the adults, and a holy war started by a man who thinks the apocalypse is God’s plan.
Chapter 2 opens with a late-night conversation between Amalfi and Dee Hazleton, and it is one of the most emotionally raw scenes in the entire series. Dee shows up at Amalfi’s door wearing a black sheath skirt, deliberately styled to look exactly how she looked when they first met centuries ago. She wants something from him. Something real.
This is it. The fourth and final novel in Cities in Flight. “The Triumph of Time” is where Blish wraps up everything. New York City has left the Milky Way galaxy entirely. They crossed intergalactic space and settled on a planet called New Earth, in the Greater Magellanic Cloud. The flying days are over. The Okie era is finished. And Mayor Amalfi, after a thousand years of wandering, is supposed to be retired.
