Schild's Ladder by Greg Egan

Illustrations for Schild's Ladder by Greg Egan

For twenty thousand years, every observable phenomenon in the universe has been successfully explained by the Sarumpaet Rules: the laws governing the dynamics of the quantum graphs that underlie all the constituents of matter and the geometric structure of spacetime. Now Cass has stumbled on a set of quantum graphs that might comprise the fundamental particles of an entirely different kind of physics, and she has travelled three hundred and seventy light years to Mimosa Station, a remote experimental facility, in the hope of bringing this tantalising alternative to life. Tchicaya has come to the Rindler to join the Yielders, but when Mariama – a childhood friend whose example inspired him to abandon his own home world and traditions for a life of travel – arrives soon after, he is shocked to discover that she plans to help the Preservationists find a way to destroy the novo-vacuum.
