Already the Universe was a hundred thousand times its age when the Xeelee left.
Somberly Poole watched the stars evaporate, through collisions, from the subsiding husks of galaxies, or slide into the huge black holes forming at the galactic centers. Then, as the long night of the cosmos deepened, even protons collapsed, and the remaining star-corpses began to crumble.
Poole wearied of puzzling over the huge, slow projects of the photino birds.
He sought out what had once been a neutron star. The carbon-coated sphere, drifting in orbit around a gigantic black hole, was being warmed — at least, kept to a few degrees above absolute zero — by proton decay within its bulk. Poole, as if seeking comfort, clustered his attention foci close to this shadow of baryonic glory.
Maybe there were other baryonic sentients left in the Universe. Maybe there were even other humans, or human derivatives. Poole did not seek them out. With the closure of the Ring, the baryonic story was done.
Michael Poole, alone, huddled close to the chill surface of the neutron star. His awareness sparkled and subsided.
The river of time flowed, unmarked, toward the endless seas of timelike infinity.
AUTHOR’S NOTE
Ring concludes the Xeelee Sequence.
The novel stands by itself, although events in three of my previous novels, as well as in related short stories, are referred to.
The high-gravitation alternate universe mentioned in Chapter 32 is explored in my novel Raft. The career of Michael Poole, first referred to in Chapter 2, is the heart of my novel Timelike Infinity. The neutron star colonization project discovered in Chapter 29 is described fully in my novel Flux.
The complete timeline of the Xeelee Sequence follows. Novels and stories in the Sequence are included, novels in capitals.
Be assured that, although Ring is the chronological end of the Xeelee story, there are tales left to be told…
