Ring is a 1994 science fiction novel by author Stephen Baxter. 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, and that of the Great Northern, a generation ship on a five-million-year journey.
The AI 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 ageing 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. It will be a five-million-year journey, though only a thousand years will elapse on board, due to relativistic time dilation effects. The crew is broken into three factions—the , the virtuals, and a survivalist faction, Superet. Their journey is a round trip taking them to the future of our solar system through relativistic time dilation.
Among 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 (anagathic or life-extension) 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 their end of the wormhole is destroyed leaving them trapped in the future. They observe that the entire universe is full of red stars (indicating that the stars have aged far faster than expected). The Northern makes contact with Lieserl, who explains her observations of the photino birds. The photino birds do not 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 'Ring' which is an escape hatch. A cosmic string is made into a loop and creates the phenomenon 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.
