Ring is a 1994 science fiction book by author Stephen Baxter.
[edit] Plot summary
Ring tells the story of the end of the universe and the saving of mankind from its destruction. Two parallel plots are followed throughout the novel: that of Lieserl, an AI exploring the interior of the sun for millions of years, and that of the Great Northern, a generation ship of humans sent on a five-million-year journey (though only a thousand years will elapse onboard, due to relativistic time dilation effects).
Lieserl is abandoned for five million years, leaving her to observe the sun's interior. She discovers dark matter -based life, which she names photino birds. These birds gradually drain the energy from the core of a star, ending fusion and causing premature aging into a stable red giant—the birds' preferred habitat, as it has no risk of going supernova and destroying them.
A generation ship is sent with one end of a wormhole to explore the future and investigate the whereabouts of Michael Poole. The crew is broken into three factions—the primitives, the virtuals, and a survivalist faction, Superet (possibly named for the Superet Light Church of the twentieth century). Their journey is a round trip taking them to the future of our solar system through relativistic time dilation.
Between the factions, the primitives are a eugenics project for Garry Uvarov who hopes to lengthen the lives of humanity without the use of Anti-Senescence technology. The Superet faction relies heavily on failing technology and maintains a totalitarian government which refuses to acknowledge the existence of other decks on the ship; the virtuals remain aloof.
Upon their arrival, the entire universe is full of red stars (indicating that the stars have aged far faster than they'd expect). The Northern makes contact with Lieserl, named after Einstein’s daughter, who explains her observations of the photino birds. The photino birds don’t just exist in our sun but every sun, helioforming them to an amenable habitat. The Xeelee, masters of baryonic matter, have known about the photino birds and have been striving to thwart them. The baryonic universe is doomed but the Xeelee create a Big Dumb Object which is an escape hatch. A cosmic string is made into a loop and creates the phenomena of the Great Attractor. The function of the Ring is to create a Kerr metric at its centre, which, in this fictional universe, creates a portal to other universes; the rotating Ring is somewhat similar to a Tipler Cylinder. Whenever humans have met up with the Xeelee and pursued war, this was merely an annoyance since the Xeelee were thinking on a larger scale about more potent enemies. The crew of The Northern and Lieserl discover the folly of their species.
A Xeelee nightfighter is discovered in Callisto and it is rigged to piggyback The Northern to the Great Attractor. Fifty days later they discover that the Xeelees' project has been destroyed but a recently awakened virtual of Michael Poole shows Spinner-of-Rope, a primitive, how to pilot around the fragmented cosmic strings and travel into the past using a closed time-like path; this method of time travel was first suggested by J. Richard Gott.
These last humans return to the Ring, in an era in which it was not destroyed; the Xeelee allow them through, and they briefly attempt to pick universes (rejecting the high-gravity universe depicted in Raft) and find sanctuary in another younger universe, after passing through the Ring, and get to work on starting a new world.
Michael Poole remains in our universe and witnesses the deaths of the last stars, and the decay of the last protons- the final victory of the dark matter lifeforms over the baryonic Xeelee and lesser races. Eventually, his consciousness disperses, and history ends.
