To Hold Up the Sky is a collection of Cixin Liu’s short fiction. The twelve stories gathered here address the relationship between humanity and the universe.

• “Contraction” examines the moment when the universe that has been expanding for billions of years begins to contract.
• “The Time Migration” follows a mass of displaced humans moving through a succession of possible futures toward a viable new home for the human race.
• “2018-04-01” posits a world in which increased longevity is possible and genuine immortality within reach – all at a very steep price.
• “Ode to Joy” features the universe itself conducting a concert which leads to an unexpected moment of hope.
• “The Thinker” imagines a vast, universal consciousness that mirrors the consciousness of the human species.

The Subterranean Press edition contains a bonus short story, “Moonlight,” which is the account of a man tasked with altering and preserving the human future three times in the course of a single night.
