Lieserl

"Lieserl" is a science fiction short story by British writer Stephen Baxter, originally published in Interzone in 1993. Appearing also in his anthology Vacuum Diagrams, it represents a small, but integral part of the novel Ring.

Set primarily on Earth in the year A.D. 3951, Lieserl documents the title character's life from birth until shortly after her physical death. The story explains how the development of nanobots has enabled virtual immortality for humans by virtue of the nanotechnological manipulation of the chemical processes that cause cells to die. Lieserl's body is engineered by such nanobots but, instead of extending her life, the nanobots cause her to age rapidly. Memories and learning are also implanted into her cortex. The combination of these effects results in Lieserl living the equivalent of 90 year life in 90 days.

Upon her physical death Lieserl's awareness is downloaded into a number of datastores, granting her a supreme consciousness. These datastores are placed within one mouth, or Interface, of a man-made wormhole which is then suspended within the Sun. The other Interface of the wormhole is left in orbit around the Sun and the pumping away of superheated gas from the Interface within the sun to the other Interface provides a refrigeration effect enabling the datastores holding Lieserl's consciousness to survive.

Lieserl is told that her existence is just one of many projects initiated by mankind to ensure the survival of the species. Lieserl's task is to study the sun since it appears to be dying, aging more quickly than was to be expected without some exterior influence. The story ends just as Lieserl begins in her work without revealing the nature of the threat to the Sun. Nevertheless, the final passages of the story contain a foreshadowing of the dark future facing the universe when Phillida, Lieserl's mother, announces that mankind "can live as long as the stars - for tens of billions of years". The novel Ring and the short stories Secret History and The Baryonic Lords, also within the Vacuum Diagrams collection, tell of the premature aging of stars caused by a dark matter life-form named photino birds and, as a consequence, the end of baryonic life within the universe.
